Foliar symptoms of a vine infected with Grapevine virus B
Grapevine virus B is associated with Corky Bark Disease. GVB. can be transmitted and spread by mealybugs in the field. HealthCheck Panel A detects all viruses associated with rugose wood disease.
Effect of leafroll disease on fruit quality
Effect of leafroll disease on fruit quality
Grapevine leafroll associated virus-symptoms include downward rolling and interveinal reddening or yellowing of leaves, depending on the color of the fruit of the grape variety. Vines infected with leafroll disease can be slightly smaller than healthy ones; grape clusters are generally smaller than normal. Reduced fruit size and yield, sugar content, and uneven/lack of maturation may be associated with virus infection. Many leafroll associated viruses can be transmitted and spread by mealybugs in the field.
Foliar symptoms of a vine infected with Grapevine fanleaf virus
Foliar symptoms of a vine infected with Grapevine fanleaf virus
Grapevine fanleaf virus causes a serious and devastating disease. Sensitive cultivars show rapid decline, low quality of fruit and yield. Affected vines are smaller than healthy vines. The life span of the vineyard decreases considerably in sensitive varieties. Up to 80% yield loss can be expected in severe infections. Grapevine fanleaf virus is transmitted by the dagger nematode Xiphinema index.

Seasonal Vineyard Survey
26 October, 2018

With life expectancies of 80+ years, grapevines are a long-term business investment. To care for them properly, it is important to pay close attention to the organization of your grapevine mother blocks and certify that your planting material is free of any known or detectable pathogens.

We offer seasonal vineyard surveys that combine state-of-the-art testing methods with on-site consulting from our leading expert pathologists. Working closely with you in the field, we discuss your specific testing needs, recommend sampling strategies to more accurately detect the presence of pathogens in spite of low concentration or erratic distribution in the vine, and provide field or nursery operation inspections to assess grapevine health. We also offer training sessions for personnel to collect samples for testing.

If you have any questions or are interested in setting up a survey contact:

Financial Assistance is available for replanting Grapevine Red Blotch infected vineyards
31 October, 2015

The USDA Farm Services Agency has included Grapevine red blotch associated virus (GRBaV) as an approved disease for financial relief when replacing infected vineyard blocks. 

The program requires testing a minimum of ten vines per block.  We have developed methods to allow the detection of GRBaV year-round. However, this is the best time of the year to correlate symptoms with the presence of virus.  When collecting samples from each vine please provide a shoot or cane cutting with leaves attached, keep track (mark it with the corresponding vine and row number) and label each vine sample separately.  We are able to test composites of up to five vines (one cutting per vine). We are able to note the sample’s symptoms in the analytical report if leaves are provided with each cane portion.   After your application is completed, possibly a USDA FAS agent will visit your vineyard to observe the symptoms in the particular block.

We have developed a photo gallery to guide you through the symptoms of many grapevine varieties: http://www.eurofinsus.com/sta-laboratories/grapevineplant-disease/grapevine-red-blotch-photo-gallery/

Our philosophy is based on superior customer service focused on educating growers and nursery personnel to understand vineyard health issues.  We are staffed with plant pathologists and technical personnel who are well versed in grapevine fungal, bacterial, and viral diseases. 

Please contact Dr. Judit Monis (juditmonis@eurofinsus.com) or  call us at 1-888-762-5220 if you need us to guide you through the sampling for confirmation of GRBaV infection in your vineyard blocks.  We are also able to help devise disease management programs for other bacterial, fungal, or viral infection.

Submit samples for HealthCheck Panel A + RB and Pierce's DiseaseTesting!
18 October, 2015

HealthCheckTM Panel A includes ELISA and RT-PCR  (two separate samples are collected and tested consecutively) for the detection of viruses associated with leafroll disease GLRaV 1-7, and -9 (includes GLRaV-2 RG), red blotch (GRBav),
Rugose wood disease ( GVA, GVB, GVD, RSPaV, RSPaV-Sy,), and  GFkV, GSyV-1.    

Samples may be collected from actively growing vines late in the growing season (September-December) or dormant vines.  We recommend providing one sample consisting of representative portions of canes, cordon, or trunk (6-8”) from each vine.  The cane material should be collected from the basal portion of the vine (i.e., older growth).  If leaves are present, please provide a representative sample for symptom tracking.   Research in our laboratory has shown that higher concentrations of viruses associated with leafroll and  rugose wood complex diseases are found in the most mature portions of the vine.

 

HealthCheckTM Panel PD. includes ELISA and RT-PCR  forthe sensitive and accurate detection of Xylella fastidiosa  We recommend submitting multiple cane and leaf (including petioles) samples representing different parts of the vine due to the erratic distribution of the bacterium.  The diagnosis of Xylella fastidiosa  is seasonal and best detected in petioles  collected late in the summer or the fall season.  Lower concentrations of virus might be detectable in samples collected from dormant canes, cordon, or trunk material.

 

Of course grapevine growers can continue to send samples for HealthCheckTM Fungal Panel!

New article on Grapevine Registration and Certification Under Review: Red Blotch associated virus in California certified plantings opens discussion
17 September, 2015

 

by Dr. Judit Monis

Some years ago I wrote an article and presented information on grapevine clean planting stock and the California 2010 Certification and Registration (R&C) program administered by the California Department of Food and Agriculture (CDFA). Since the adoption of the new regulations, a new foundation block was planted and progeny material is slowly becoming available to growers. The recent report of Grapevine red blotch associated virus (GRBaV) in California certified planting material has opened discussion on needed revisions of the current R&C program. The CDFA has hosted several public meetings in 2014 and 2015 to collect feedback from growers and industry representatives concerned on issues regarding the 2010 regulations.  Specifically, the vineyard industry is concerned with the traceability of stock, location of increase and certified blocks, eligibility requirements, standards for suspending or cancelling certification, the detection of GRBaV in certified planting material, among other issues. As a consequence, a committee will be assigned by the California Secretary of Agriculture to work on solving these issues and developing regulations that are acceptable to the California grape industry. 

 The article focuses on the challenges of certification and registration programs and hopes to provide guidelines to growers who wish to plant healthy grapevines.  Follow the link to read the entire article

Dr. Judit Monis to present Grapevine red blotch research at the International Grapevine Virology Congress
04 September, 2015

Eurofins STA will present research related to the detection of Grapevine red blotch associated virus (GRBaV) at the International Grapevine Virology Congress (ICVG) to be held this year in Ankara, Turkey.

The work shows that Grapevine red blotch virus is detected in all vine parts.  Samples were collected from known infected and uninfected field samples throughout the year (fall, winter, spring, and summer) using material from different sections of the vine.  Vine samples collected from basal and apical positions in the vine comprising green or lignified canes, codon and trunk were tested using our proprietary extraction and testing procedures.  The results showed that the detection of GRBaV was equally sensitive throughout the season in all grapevine tissues tested.  Furthermore, the analyses of newly grafted vines in which the scion was known to be infected yielded equivalent PCR detection signals in the scion and rootstock portions sampled. This data suggests that the virus can move from the infected scion into the rootstock in a short period of time (less than three months).  Symptoms of different grapevine varieties and sampling guidelines developed in our lab for the detection of GRBaV will be presented.

The ICVG meeting, held every three years to promote collaboration and interaction amongst plant pathologists who specialize in grapevine viruses, viroids, and phytoplasmas.   For the past several years, Judit has written informative articles to cover the most important topics covered at the meeting and plans do the same again this time.

Update on Grapevine Clean Planting Stock Program - Recording available
29 August, 2015

By Judit Monis, Ph.D., Division Manager, Plant Health Services, STA Laboratories, Gilroy, CA

Recording available is available for viewing the webinar on Grapevine Clean Planting Stock Program. The California Grapevine Registration and Certification (R&C) Program was revised in 2010.  The 2019 regulations, include specific rules for traceability, distance of increase blocks from commercial fruit-bearing (non-registered) vineyards, and disease diagnostic with vines propagated using a tissue culture technique with the aim of eliminating harmful viruses.  The webinar provides details of the “Protocol 2010” disease testing and an update on the recent discussions to include Grapevine red blotch associated virus (GRBaV) in the California R&C program and the USDA Farm Services Agency available financial relief when replanting an GRBaV infected vineyard block.  Ultimately, we hope to highlight the need for growers and nurseries to develop routine testing programs to complement the current and future R&C diagnostic programs in order to avoid the potential transmission and spread of pathogens.  In other words, we still recommend testing planting material for the presence of GRBaV and other known important viruses (e.g., Grapevine leafroll and Vitiviruses) that may have escaped detection in the R&C Program.

Eurofins STA Labs to Present Research at the 2015 Plant Pathology Annual Meeting
24 July, 2015

By Laura A Miles, M.S.

Grapevine diseases caused by fungal pathogens are a common and complex problem in grape growing regions around the world.  Fungal pathogens enter the host primarily through pruning wounds , which make the plant vulnerable to single or multiple infections and, in many cases (such as, Eutypadieback and Bot canker), disease symptoms are not evident until several years post-infection.

Currently, host resistance to trunk diseases has not been discovered in grapevine germplasm.  Therefore, grape growers rely on vineyard disease management practices that are expensive and often ineffective unless  adopted early. 

At Eurofins STA Laboratories, the HealthCheckTM Fungal Panel was developed to reliably isolate fungal organisms from grapevine tissue.  Over the years, we have tested hundreds of grapevine samples from California. We work with growers and nursery personnel to help them understand particular vineyard health issues.

This year, we are presenting our findings on diversity and frequency of fungi associated with symptomatic grapevines in California at the 2015 American Phytopathological Society (APS) Annual Meeting to be held in Pasadena, California, August 1-5.

New article: Tips For Grapevine Trunk Disease Diagnostics, Prevention, and Control
28 June, 2015

Various pathogens and environmental factors are considered to be major threats to the vineyard’s health. Pathogens are disease causing organisms such as fungi, bacteria, viruses, nematodes, and insects.  In addition, adverse environmental conditions such as frost, hail, heat, chemical injury, nutrient toxicity or deficiency, improper cultural practices and sanitation have an effect on vineyard health. As an example, a vineyard might be infected with pathogens without showing symptoms until adverse environment conditions compromise the plant defense mechanisms and trigger disease progression. Our lab focuses on the detection and control of pathogens that are propagated by grafting (i.e., graft transmitted pathogens).  However, many fungal pathogens and Agrobacterium spp. can be dispersed (short and long distance) by wind, rain and/or irrigation splashes.

Last chance to register! Update on Grapevine Red Blotch and other Red-Leaf Causing Viruses
02 May, 2015

 

By Judit Monis, Ph.D., Division Manager, Plant Health Services, STA Laboratories, Gilroy, CA

Grapevine red blotch associated virus (GRBaV) is a newly reported virus shown to be associated with red, patchy leaves, and reduced sugar content in red fruited grape varieties. However, the virus is capable of infecting white fruited varieties without displaying red leaf symptoms. Other known viruses such as leafroll (GLRaVs) and Vitiviruses (GVA, GVB, etc.) can cause similar symptoms in grape varieties.  In other words, the symptoms can be confused the vineyard.  Because the biology (transmission and effects) of these viruses is diverse it is important to recognize which virus is infecting the vineyard.

This webinar present the most updated information on red blotch,  leafroll, and other important grapevine infecting viruses. The aim is to provide up-to-date information on our knowledge in diagnostics, transmission, and control.

Spring Season Testing Grapevine Red Blotch virus can be added to HealthCheckTM Panel B!
16 April, 2015

The spring and early summer are the best time to test for decline causing viruses such as Grapevine fanleaf virus (GFLV), Arabis mosaic virus (ArMV), Tobacco ringspot virus (TRSV), and Tomato ringspot virus (ToRSV). We recommend submitting multiple shoot tip and leaf samples representing different parts of the vine.Research in our lab has shown that Grapevine red blotch associated virus (GRBaV) is readily detected in the same samples allowing to test for multiple viruses in the same sample.  Of course grapevine growers can continue to send samples for HealthCheckTM Fungal Panel and Panel CG year round.

If planning to plant a new vineyard or grafting over an established vineyard we can help develop a testing plan.  This will avoid the mistake of planting infected plant material.  Our disease panels detect all strains and species of leafroll and other detrimental pathogens. 

This time of the year, samples for Panel B or GFLV or RB are perishable.  We suggest that you keep the samples in a cooler while you are in the vineyard if it is very hot  and keep them in the cooler until they shipped. If you are using a coolant, please make sure that you have enough insulation (news or other paper is OK). Also we recommend using a water based coolant (not the blue gel as these can also heat up when heated). Some people fill water bottles and place them in the freezer in advance.  It is important to ship by overnight currier.  Please do not ship on a Friday!

Please call or email Dr. Judit Monis (juditmonis@eurofinsus.com) to discuss your vineyard planning. Also check our website for regular updates on seasonal detection of grapevine pathogens and view recorded educational webinars: http://www.stalabs.com/products-services-grapevine-testing.html

If you missed joining us for the webinar session on  November 19th please click on the following link:

http://bit.ly/1r0TYKR  

You are invited to hear Dr. Monis discuss different scenarios for sampling for disease detection.  Choosing the correct sample for pathogen diagnostics is essential to obtaining reliable results in the laboratory.   Clonal grapevine propagation, the process of making cuttings from an original vine, can severely impact the health of a vineyard.   When infected mother vines are propagated, grapevine pathogens are perpetuated in the vineyard.  Grapevine pathogen diagnostics requires the submission of a specific number and type of samples for testing at the laboratory. The aim of this webinar is to provide guidelines for the collection of representative samples for pathogen detection in the lab.  It explores different testing scenarios, whether an infection is suspected or not, the reason for testing, and what pathogen must be detected.  

Please check our website to learn more about the seasonal detection of grapevine pathogens: http://www.stalabs.com/products-services-grapevine-samples.html

14 November, 2014


Choosing the correct sample for pathogen diagnostics is essential to obtaining reliable results in the laboratory.   Clonal grapevine propagation, the process of making cuttings from an original vine, can severely impact the health of a vineyard.   When infected mother vines are propagated, grapevine pathogens are perpetuated in the vineyard.  Grapevine pathogen diagnostics requires the submission of a specific number and type of samples for testing at the laboratory. The aim of this webinar is to provide guidelines for the collection of representative samples for pathogen detection in the lab.  It explores different testing scenarios, whether an infection is suspected or not, the reason for testing, and what pathogen must be detected. 

Join us for an educational webinar:

All leafroll virus variants are detected
12 October, 2014

The key to trusted laboratory results is to have each method validated using many vineyard (field) samples rather than a few laboratory positive and negative controls.  It is known that Grapevine leafroll associated viruses are continuously mutating (are prone to genetic changes) because RNA viruses lack the proofing mechanism available to DNA viruses.  As a consequence, several strains of Grapevine leafroll associated virus-3 are known to infect vineyards in single or mixed populations.   This concept is not new to the experienced plant pathologists at Eurofins STA laboratories.  An article on Laboratory Methods for Grapevine Virus Testing Download  was written that describes and compares different testing methods available for grapevine virus detection.  Furthermore, results from a comparative study is presented in a recorded webinar by Dr. Judit Monis and is available at our website or by clicking this Link.

At Eurofins STA samples are always tested with a combination of methodologies to assure confidence of results.  Rest assured, our testing panels use two complementary detection techniques with broad spectrum and specific detection capabilities are able to detect all variants of leafroll viruses.  The application and use of best processes, high quality material, and state of the art equipment with knowledgeable and trained personnel is the foundation for trusted results.

Please call Judit Monis (1-888-782-5220 or juditmonis@eurofinsus.com) to discuss your testing needs or visit our website: http://www.stalabs.com/products-services-grapevine-testing.html for updates on grapevine diseases.

Now is the time to submit samples for HealthCheck Panel A + RB Testing!
20 September, 2014

 

HealthCheckTM Panel A includes ELISA and RT-PCR  (two separate samples are collected and tested consecutively) for the detection of GVA, GVB, GVD, GFkV, GLRaV 1-7, and -9 (includes GLRaV-2 RG) , RSPaV, RSPaV-Sy,GSyV-1.    Grapevine red blotch associated virus can be added for more complete detection.

Samples may be collected from actively growing vines late in the growing season (September-December) or dormant vines.  We recommend providing one sample consisting of representative portions of canes, cordon, or trunk (6-8”) from each vine.  The cane material should be collected from the basal portion of the vine (i.e., older growth).  If leaves are present, please provide a representative sample for symptom tracking.   Research in our laboratory has shown that higher concentrations of viruses associated with leafroll and  rugose wood complex diseases are found in the most mature portions of the vine.

 

Of course grapevine growers can continue to send samples for HealthCheckTM Fungal Panel!

Not only Red Blotch Virus affects Fruit and Wine Quality
13 September, 2014

 A lot of attention has been focused on Grapevine red blotch associated virus (GRBaV), the virus described in 2012 detected in vineyards in USA and Canada.  Due to the similarity of foliar symptoms it is likely that GRBaV infection was confused with leafroll disease or other disorders that cause reddening in red fruited grape varieties for a long time.  In spite of its name, GRBaV affects white fruited varieties too.   Besides the typical foliar symptoms, GRBaV has been reported to affect sugar accumulation in grapevines reducing the brix values and delaying the harvest of fruit. 

However, we must not forget that leafroll disease caused by different species of Grapevine leafroll associated virus (GLRaV) remains to be as important or perhaps more important than the recently discovered GRBaV.  Leafroll disease is known to negatively affect grape sugar accumulation, yield, and ultimately affects the quality and coloration of wine. 

Many of the leafroll associated viruses are able to spread in the vineyard with the aid of insect vectors.  For example, mealybugs and soft scale insects can transmit GLRaV -1, 3, -4, and other related Ampeloviruses.  

Due to the dryer climatic conditions, disease symptoms in the vineyard are appearing earlier this year.  Please call Judit Monis (888-782-5220 or juditmonis@eurofinsus.com) to discuss your testing needs our visit our website http://www.stalabs.com/products-services-grapevine-testing.html for updates on grapevine diseases.


It’s time to test for Panel PD- Short window until leaves fall
07 September, 2014

Pierce’s Disease is caused by the bacterium Xylella fastidiosa.  The bacteria can infect many different plant species including riparian vegetation and ornamentals.  Infection in grapevines causes vine decline and death.  Symptoms include scorching of leaves, defoliation (often times petioles remain attached to the cane), uneven maturation of canes and wilting of fruit clusters. Symptoms can be confused with viral and fungal decline and therefore it is important to subject samples to disease testing to determine the cause of symptoms.  Xylella fastidiosa is spread and transmitted by leafhoppers (glassy-winged, blue-green, and green sharpshooters). 

 

The diagnosis of Xylella fastidiosa  is seasonal and best detected in petioles  collected late in the summer or the fall season.  Lower concentrations of virus might be detectable in samples collected from dormant canes, cordon, or trunk material.  At Eurofins STA laboratories we have developed HealthCheck Panel PD for the sensitive and accurate detection of Xylella fastidiosa.  We recommend submitting multiple cane and leaf (including petioles) samples representing different parts of the vine due to the erratic distribution of the bacterium.

View the Newest red blotch information presented at a the American Phytopathological Society Annual meeting
11 August, 2014

Eurofins STA will present research related to the detection of Grapevine red blotch associated virus (GRBaV) at the annual American Phytopathological Society (APS) meeting to be held this year in Minneapolis.

The work performed internally by Eurofins STA scientists shows that the virus is detected in all vine parts.  Samples were collected from known infected and uninfected field samples throughout the year(fall, winter, spring, and summer) using material from different sections of the vine.  Vine samples collected from basal and apical positions in the vine comprising green or lignified canes, codon and trunk were tested using our proprietary extraction and testing procedures.  The results showed that the detection of GRBaV was equally sensitive throughout the season in all grapevine tissues tested.  Additionally, our lab has developed and implemented a sensitive assay using quantitative (Q) PCR.  This recent addition fulfills our testing strategy that allows our lab to apply many different methodologies to complement each other to offer the most comprehensive and sensitive detection services.

It is exciting news that there will be no submission gap for GRBaV testing as samples can be collected and submitted to our lab year round. Click here to view our presentation, Symptom Expression and Detection of Grapevine red blotch virus in Red and White-Fruited Grape Varieties.

Please call Judit Monis (888-782-5220 or juditmonis@eurofinsus.com) to discuss your testing needs or visit our website (http://www.eurofinsus.com/stalabs/products-services-grapevine-testing.html) for updates on grapevine diseases.


Grapevine Red Blotch Virus Affects Wine Quality
04 August, 2014

Grapevine red blotch associated virus (GRBaV) a newly described virus associated with red blotch disease found infecting vineyards in California and throughout USA, and Canada is still the virus du jour.  This virus affects red and white fruited grape varieties, but most importantly vines infected with this virus  appear to have  lower sugar contents with a  reduction of the brix values and delayed fruit maturity.

Our lab developed a reliable testing method to detect GRBaV and have tested a great number of vines that are infected with the virus (click here to see our photo gallery). The sensitive test developed at our lab allows the detection of the virus associated with Grapevine red blotch disease from different vine parts.  So far, the GRBaV is detected in all tissues tested: leaf blades (both mature and new), petioles, green or lignified canes, as well as cordon, and trunk tested.  Our work has shown that the virus appears to be evenly distributed in the grapevine and was detected throughout the season.

Therefore samples can be collected now (green tissues collected in the summer)!  Please collect 4-5 canes with leaves attached (could combine up to five vines) and place in a small zip lock bag.

We welcome you to visit our website to view our most recent educational webinar on Grapevine Red Blotch vs. Leafroll and learn more about these different important viral diseases.

The Usual Fungal Suspects
16 July, 2014

Grape diseases caused by fungal pathogens are frequently overlooked and misdiagnosed because disease symptoms are often attributed to other biotic or even abiotic factors (for example, cultural practices). This is particularly true for fungal pathogens that are implicated in the premature decline and death of grapevines.

At Eurofins STA Plant Health Services, we have developed the HealthCheckTM Fungal Panel for the rapid and accurate identification of grapevine fungal pathogens. We apply traditional microbiological methods (such as culturing on isolation media) in combination with molecular techniques for the diagnosis of grapevine trunk diseases.

We welcome you to visit our website to view our most recent webinar on Grapevine Trunk Diseases. In this webinar we discuss the most common plant pathogens and symptoms of vine decline and canker disease to help you recognize problems associated to fungal pathogens in your vineyard.

Eurofins STA develops new test for the detection of red blotch virus
07 July, 2014

Grapevine red blotch associated virus (GRBaV) causes red blotch disease in red but also affects white fruited grape varieties.   Besides the typical foliar symptoms, GRBaV has been reported to affect sugar accumulation in grapevines reducing the brix values and delaying the harvest of fruit.

Our lab has been applying a reliable testing method to detect GRBaV for many years and have tested a great number of vines that are infected with the virus.  More recently we developed and validated a new method.  This is a sensitive assay using quantitative (Q) PCR also known as real time PCR.  This recent addition fulfills our testing strategy that allows our lab to apply many different methodologies to complement each other to offer the most comprehensive and sensitive detection services.

Summer Season Disease Testing for Best Wine Quality
16 June, 2014

As the summer season approaches, it is a good time to scout the vineyard and look for the presence of symptoms associated with diseases in the vineyard that affects the quality of grapes and ultimately the wine. 

The decline causing viruses (detected with HealthCheck Panel B) are known to be specifically transmitted by nematodes.  The best known representatives are  Arabis mosaic (ArMV), Grapevine fanleaf (GFLV), Tobacco (TRSV) and Tomato ringspot (ToRSV) viruses that cause severe decline symptoms  accompanied by leaf deformations (hence the name fanleaf). There is a high degree of specificity between the viruses and the nematode vectors able to transmit them: ArMV is transmitted by Xiphinema diversicaudatum, ToRSV and TRSV are transmitted by Xiphinema americanum, and GFLV is transmitted by the dagger nematode Xiphinema index,In an infected vineyard (even after removal) nematodes are able to transmit the viruses for many years.  In France and California, studies have shown that vineyards previously infected with GFLV and populated with Xiphinema index are able to infect newly planted vines at least eight years after the vineyard was removed.   Decline symptoms can also be caused by different fungi and bacteria. For example, Phaeoacremonium and Phaeomoniella,species  cause young vine decline (also known as Petri disease) and Esca disease in older vines (over 10 years).  Cylindrocarponspecies. (now known as Ilyonectria) causes “Black foot Disease” which is manifested by delayed shoot growth and decline. Recently, a webinar of trunk diseases was presented by Dr. Judit Monis and is available for viewing in our website.

WATCH OUR WEBINAR: Leafroll vs. Red Blotch
09 May, 2014

Grapevine red blotch associated virus (GRBaV) was shown to be associated with red, blotchy leaves, and reduced sugar content in red fruited grape varieties. So far it does not appear that the virus affects grape production yields.  Although the molecular structure of the viruses associated with grapevine red blotch and leafroll (GLRaV) are strikingly different, the symptoms developed in the vineyard can usually be confused.

In this webinar, we will compare and contrast the most updated information on red blotch and leafroll disease diagnostics, transmission, and control.

Grapevine red blotch associated virus (GRBaV) was shown to be associated with red, blotchy leaves, and reduced sugar content in red fruited grape varieties. So far it does not appear that the virus affects grape production yields.    Although the molecular structure of the viruses associated with grapevine red blotch and leafroll (GLRaV) are strikingly different, the symptoms developed in the vineyard can usually be confused.  Due to the novel character, information on the biology and epidemiology of GRBaV is limited.  In contrast, the detection, epidemiology, and control of leafroll associated viruses have been well documented.  To fill this gap, our lab has on-going collaboration with academic experts working on elucidating and characterizing the genetics and biology of GRBaV.  Based on the research in progress we expect that soon we will be able to make inferences on GRBaV expected epidemiology and biology.

Marc Fuchs from Cornell University presented the latest of their research and confirmed that Grapevine red blotch associated virus causes red leaf symptoms in tissue culture plants.  This is the second virus (Grapevine fanleaf was the first) for which researchers have completed Koch’s postulatesMore work will be needed to determine if the virus has an effect on fruit maturation or sugar accumulation.

                    

Due to the similarity of foliar symptoms it is likely that GRBaV infection has been confused with leafroll disease and other disorders that cause reddening in red fruited grape varieties. Besides the typical foliar symptoms, GRBaV has been reported to affect sugar accumulation in grapevines reducing the brix values and delaying harvest of fruit.

We created a Grapevine red blotch associated virus photo gallery to allow you to compare symptoms in the vineyard with different varieties that were confirmed to test positive for the virus.  Please click on the link:

Grapevine red blotch associated virus is easily detected in the laboratory using molecular tools.  During the past year, Eurofins STA lab has done exhaustive research and determined that GRBaV is detectable in all parts of the grapevine.  Our tests were performed using different tissues (young shoots, leaf blades and petioles from mature or young leaves, flowers, canes, trunk, etc.).  So far GRBaV has not shown the same seasonal variability reported for leafroll associated viruses (i.e., it is detectable throughout the year in all grapevine parts of the vine).   Although, GRBaV is a DNA virus, we are able to test for this virus in combination with HealthCheckTM Panel A (detects leafroll and rugose wood diseases), HealthCheckTM Panel B (detects viruses that cause grapevine decline) and HealthCheckTM Panel PD making the testing cost effective.

Grapevine Red Blotch Disease through the Looking Glass: Update and Detailed Photo Gallery
18 November, 2013

Did you missed seeing Dr. Judit Monis  (Eurofins STA Labs, Plant Health Services expert virologist and plant pathologist) at the Napa Valley Growers Association Wine and Grape Expo?  You will have another opportunity at the NCWIE in Santa Rosa on December 5. 

Dr. Monis did a presentation at the  Napa Valley Growers Association Wine and Grape Expo to update the audience on  Eurofins STA Laboratories testing  Grapevine red blotch associated virus (GRBaV)  program for the last year. As we pass this anniversary, we reflected on what is known about Grapevine Red Blotch disease, GRBaV (the virus associated with the disease), and have prepared a special WEB page compiling useful information about Red Blotch Disease including a link to a comprehensive gallery of photos showing Red Blotch symptoms in grapevines of many different wine grape varieties:

www.eurofinsus.com/stalabs/Red-blotch-disease.html

Grapevine red blotch associated virus is a newly described virus associated with grapevine Red Blotch disease found infecting vineyards in California and throughout USA and Canada.  Initial concern was based on the family of virus that GRBaV belongs to, namely the Geminiviridae, which is important in tomatoes.  GRBaV is different from most other known grapevine infecting viruses in that it is DNA-based, rather than RNA-based, in its genetic code.

 

Presumably, GRBaV has been in vineyards for quite a while, but has only received attention after it was discovered during a recent search for new viruses in grapevines with a novel technique.  Once discovered, it was associated with the presence of red, blotchy leaves and reduced sugar content in red fruited grape varieties.  Hence, the names of the disease and the virus, Red Blotch and Grapevine red blotch associated virus, respectively. 

It is likely that Red Blotch disease  might have been confused with other grapevine disorders that manifest similar symptoms.  These disorders include infection by leafroll viruses or fungal pathogens, insect feeding damage, vine nutritional deficiencies, environmental stresses (freeze, heat, lack of or excessive moisture), soil conditions, physical damage (gophers, machine injuries), poor vineyard management, etc.  Not surprisingly, our laboratory also reported that specific fungi were found in vines showing symptoms similar to Red Blotch prior to the discovery of GRBaV.  In short, determining the cause for Red Blotch symptoms is still confusing.

Adding to the confusion, in spite of its name, GRBaV does not always produce Red Blotch symptoms.  For example, it affects white fruited varieties such as Chardonnay or Sauvignon Blanc without showing red blotch symptoms. While leaf discoloration is disconcerting, more importantly, GRBaV has been reported to affect sugar accumulation in grapevines resulting in reduced Brix values and delayed fruit maturity.

 

Presently there is no information on the biology of GRBaV.  While there are anecdotal reports that Red Blotch is spreading rapidly throughout California vineyards, there is no field data supporting this viewpoint. Within a laboratory setting it has been reported by Washington State researchers that the “Virginia Creeper” leafhopper is able to transmit the GRBaV.  While this is interesting, clearly more data and research are needed to confirm transmission in the vineyard and determine if other insects are capable of spreading the GRBaV from vine to vine.

As soon as GRBaV was reported at the International Grapevine Virus Congress in October 2012, Eurofins STA Laboratories developed a reliable testing method (HealthCheck Panel RB) to detect GRBaV (we are likely the first lab to offer the test to growers and nurseries). During HealthCheck Panel RB qualification period, we tested a great number of vines that were infected with the virus. We determined that our method can reliably detect GRBaV from any portion of the vine, in contrast to others reporting there are sampling limitations regarding Red Blotch detection.  We are confident that GRBaV can be accurately detected in all tissues: leaf blades (both mature and new), petioles, green or lignified canes, as well as cordons and trunks. In addition, the virus is detectable throughout the different seasons. Consequently, we are able to offer HealthCheck Panel RB in combination with other popular HealthCheck Panels (A, B, or PD).

You can always trust Eurofins STA Laboratories to have the most complete and reliable grapevine testing program anywhere.  We offer a wide menu of services to the viticulture industry including bacterial, fungal, and viral testing as well as disease elimination using meristem tissue culture.  Feel free to call our lab with questions about Red Blotch symptoms or any other general vineyard health issue.  Our website is always a resource with articles and information on grapevine diseases- please click on the link:  www.eurofinsus.com/stalabs/products-services-grapevine-testing.html or call us at (408) 846-9964 or toll free at (888) 782-5220.

Eurofins STA has been testing for the presence of Grapevine red blotch associated virus (GRBaV) for over a year.  We have created a photo gallery that illustrates symptoms associated with GRBaV infection in different grapevine varieties. 

Grapevine red blotch associated virus is a newly described virus associated with grapevine red blotch disease found infecting vineyards in California and throughout USA, and Canada. Due to the similarity of foliar symptoms it is likely that the effect of GRBaV infection was confused with leafroll disease or other disorders that cause reddening in red fruited grape varieties. In spite of its name, GRBaV affects white fruited varieties too. Besides the typical foliar symptoms, GRBaV has been reported to affect sugar accumulation in grapevines reducing the brix values and delaying the harvest of fruit.

Fungal Pathogens Cause Important Diseases in the Vineyard
08 October, 2013

As the harvest season progresses, this is the best time to flag vines and map symptoms in the vineyard.  Many of the symptoms in the vineyard may be similar and others are characteristic of specific disease causing agents. 

Recently, a lot of attention has been focused on Grapevine red blotch associated virus a newly described virus detected in vineyards in USA and Canada.   However, Leafroll associated viruses and fungal pathogens can cause reddening in red fruited grape varieties as well.  Of course these pathogens also affect white fruited varieties too.   The effects and signs of fungal infection can be observed in the older wood of vines (especially vines trained with unilateral or bilateral cordons).

The Eurofins STA HealthCheck Fungal Panel was developed to specifically survey and identify many grapevine fungal pathogens using traditional microbiological diagnostic methods with the aid of a microscope. More recently, we have developed state-of-the-art molecular techniques for the rapid and accurate identification of pathogens by sequencing a portion of the pathogen’s genome. The availability of different diagnostic approaches allows our lab to handle fungi (and other pathogens) that are difficult to identify due to their inability to produce typical spores, lack of specific morphological features, or genetic variation. Therefore our lab can identify the wide range of fungal pathogens found in grapevines.

Most frequently our lab isolates and identifies the following pathogens that are associated with many important diseases in the vineyard: Botryosphaeriaceae spp. (Bot-like canker), Diatrypaceae spp. (Eutypa dieback), Phaeoacremonium Phaeomoniella,and Pleurostomophora (formerly Phialophora)spp. (young vine decline also known as Petri or Esca diseases), Phomopsis spp., and many others. In addition, many soil borne pathogens such as Armillaria spp., Cylindrocarponspp. (Black foot disease), Cylindrocladium spp., Verticillium spp., Phytophthora spp., and Fusarium spp. can be detected. Our expert team excels at handling special situations and strives to report the most accurate results.

Grapevine Red Blotch Virus is Detected in all Vine Parts
19 September, 2013

For some reason I call Grapevine red blotch associated virus (GRBaV) “the virus du jour”.   Might be because of the attention focused on GRBaV, a newly described virus associated with red blotch disease found infecting vineyards in California and throughout USA, and Canada.  Due to the similarity of foliar symptoms it is likely that the effect of GRBaV infection was confused with leafroll disease or other disorders that cause reddening in red fruited grape varieties.  In spite of its name, GRBaV affects white fruited varieties too.   Besides the typical foliar symptoms, GRBaV has been reported to affect sugar accumulation in grapevines reducing the brix values and delaying the harvest of fruit.

As soon as this virus was reported at the International Grapevine Virus Congress in Davis, our lab developed a reliable testing method to detect GRBaV (we are likely the first lab to offer the test to growers and nurseries).  Throughout the year we have tested a great number of vines that were infected with the virus. The sensitive test developed at our lab allows the detection of the virus associated with Grapevine red blotch disease from different vine parts.  So far, the GRBaV is detected in all tissues tested: leaf blades (both mature and new), petioles, green or lignified canes, as well as cordon, and trunk tested.  Our work has shown that the virus appears to be evenly distributed in the grapevine and was detected throughout the season in spite of earlier rumors that predicated low virus titer in green tissues collected in the spring.

Due to the dryer climatic conditions, disease symptoms in the vineyards are appearing earlier this year.  Please call Judit Monis (888-782-5220 or juditmonis@eurofinsus.com) to discuss your testing needs or visit our website (http://www.eurofinsus.com/stalabs/products-services-grapevine-testing.html)  for updates on grapevine diseases.


Not only Red Blotch Virus affects Fruit and Wine Quality
03 September, 2013

A lot of attention has been focused on Grapevine red blotch associated virus (GRBaV), a newly described virus detected in vineyards in USA and Canada.  Due to the similarity of foliar symptoms it is likely that GRBaV infection was confused with leafroll disease or other disorders that cause reddening in red fruited grape varieties for a long time.  In spite of its name, GRBaV affects white fruited varieties too.   Besides the typical foliar symptoms, GRBaV has been reported to affect sugar accumulation in grapevines reducing the brix values and delaying the harvest of fruit. 

However, we must not forget that leafroll disease caused by different species of Grapevine leafroll associated virus (GLRaV) remains to be as important or perhaps more important than the recently discovered GRBaV.  Leafroll disease is known to negatively affect grape sugar accumulation, yield, and ultimately affects the quality and coloration of wine. 

Many of the leafroll associated viruses are able to spread in the vineyard with the aid of insect vectors.  For example, mealybugs and soft scale insects can transmit GLRaV -1, 3, -4, and other related Ampeloviruses.   Recently, it was reported that GRBaV could be transmitted by the Virginia Creeper leafhopper (Erythroneura ziczac).  Of course more work is needed to substantiate this finding but growers should be on the look up for E. ziczac that was already found in different wine growing regions in California as well as Western United States.

It’s time to test for Panel PD- Short window until leaves fall
23 August, 2013

Pierce’s Disease is caused by the bacterium Xylella fastidiosa.  The bacteria can infect many different plant species including riparian vegetation and ornamentals.  Infection in grapevines causes vine decline and death.  Symptoms include scorching of leaves, defoliation (often times petioles remain attached to the cane), uneven maturation of canes and wilting of fruit clusters. Symptoms can be confused with viral and fungal decline and therefore it is important to subject samples to disease testing to determine the cause of symptoms.  Xylella fastidiosa is spread and transmitted by leafhoppers (glassy-winged, blue-green, and green sharpshooters). 

The diagnosis of Xylella fastidiosa  is seasonal and best detected in petioles  collected late in the summer or the fall season.  Lower concentrations of virus might be detectable in samples collected from dormant canes, cordon, or trunk material.  At Eurofins STA laboratories we have developed HealthCheck Panel PD for the sensitive and accurate detection of Xylella fastidiosa.  We recommend submitting multiple cane and leaf (including petioles) samples representing different parts of the vine due to the erratic distribution of the bacterium.

Latest Updates on Research on Red Blotch the Virus “du Jour”
19 August, 2013

Our plant pathologist specialized in grapevine diseases, Judit Monis, just came back from the APS (American Phytopathological Society) meeting held in Austin TX.  Of course the newly discovered Grapevine red blotch was a topic of discussion.   If you do not know, Dr. Monis has over 25 years of experience working in plant pathology with focus on grapevine viruses, bacteria, and fungi. She had the privilege to meet personally with Drs.  Marc Fuchs (Cornell University), Mysore Sudarshana (aka Sudi from USDA ARS Davis), and Deborah Golino (FPS, UC Davis) to learn more from these experts.

We have been covering Grapevine red blotch associated virus many ways: newsletter articles, update webinars (Link), and articles in trade journals (Download).  Here just brief updates from the meeting:

At UC Davis, the Foundation Plant Services laboratory announced that all vines in the newly planted Russell Ranch are free of GRBaV.  The same lab announced that only three out of the 1610 vines in the classic foundation tested positive for the virus.  The researchers explain that the low level of infection might be due to the woody indexing test applied to screen against leafroll infection may have weeded out vines that were infected with GRBaV,  Another report from UCD shows the transmission of GRBaV to healthy vines by chip budding.

At the ASEV meeting in June, Marc Fuch announced the success of artificially inoculating healthy tissue culture grown grapevines with GRBaV. In addition, the work was able to show red leaves in the infected plants.  The researchers have moved the plants to the greenhouse and the results seem to be still holding true.  The challenge in my opinion is that plants need to  grow into vines to show that the grapes (and wine) are affected by the virus.  We will be on top of the subject and will update you accordingly.

Early and Accurate Detection of Leafroll, Rugose Wood and Red Blotch Associated Viruses
26 July, 2013

Over the years our clients have requested early testing of vines because the information is needed  to make important vineyard management decisions (for example grafting over a vineyard). We have done comparative experiments and have determined that it is possible to test for grapevine leafroll, rugose, and red blotch associated viruses (HealthCheck Panel A + RB)  in mid and late summer. Our team has strong on-going collaboration with researchers in USA as well as international labs working on management of disease transmission as well as early pathogen detection.   Please call Dr. Judit Monis to learn more about specific sampling needs as this is the key to the success in reliable testing.  Also check our website (http://www.eurofinsus.com/stalabs/products-services-grapevine-testing.html) for updates and recorded educational webinars.

Download new article “Global Discussion on Vineyard Trunk Diseases”
04 February, 2013

The session began with a controversial presentation by French scientists suggesting that bacterial rather than fungal pathogens might be the primary cause of grapevine trunk disease. The work using both molecular and microbiological experimental methods based its premise on the observation that similar fungal diversity is equally present in healthy and diseased vines. In contrast, they observed a large diversity of species of bacterial populations between healthy and symptomatic vines. Their conclusion that bacteria, rather than fungi, cause trunk diseases goes against the well-accepted etiology (cause of disease) of many known and characterized trunk diseases such as young vine decline (aka Petri Disease), Esca, and Bot Canker in which the fungal pathogens are endophytic organisms that live and colonize a vine without causing any disease until the vine is stressed. In other words, the traditional point of view is that the same fungal populations are present in healthy and diseased vines.

Protect Your Grapevines during the Harvest Season with HealthCheck™ Panel A
29 August, 2012

Best wishes for the upcoming Harvest Season from Eurofins STA!  Now is the best time to defend your grapevines from this season’s common viruses by using HealthCheck™ Panel A Testing!  

HealthCheck™ Panel A includes ELISA and RT-PCR detection of GVA, GVB, GVD, GFkV, GLRaV 1-7, & -9 (includes GLRaV-2 RG) , RSPaV, RSPaV-Sy, GSyV-1. 

Samples can be collected either from actively growing vines during the growing season from September through December, or from dormant vines.  We recommend providing one representative sample consisting of portions of canes, cordon, or trunk (6-8”) from each vine.  This is important to ensure the best detection of infections and prevent the possible spread to the rest of the vineyard.  The cane material should be collected from the basal portion of the vine (i.e., older growth).  If leaves are present, please provide a representative sample portion of this also, for symptom tracking.  INSIDE TIP:  Our research has shown that higher concentrations of viruses associated with Leafroll and Rugose Wood Complex diseases are found most commonly in the mature portions of the vine.

It is still very beneficial to continue monitoring your grapevines with the HealthCheck™ Fungal Panel during this time of the year!

Please visit our website to learn more our Grapevine Disease Diagnostic Program: http://www.eurofinsus.com/stalabs/products-services-grapevine-healthcheck.html

Please remember to use our Grapevine Disease Testing Shipping Label(289 KB) and include sample origin information with your sample submission.

Red Blotch Symptoms in California Vineyards
06 December, 2011

Red Blotch Symptoms in California Vineyards
By Judit Monis, Ph.D. Eurofins STA Labs, Plant Health Services

During the 2011 fall season, there was a growing concern about foliar symptoms observed in the vineyards.  Most recently, the condition has been significant enough to earn itself a namesake, Red Blotch.  The symptoms are described as red, pink, crimson orange, or purple leaves often times with patchy or blotchy coloration with green, yellow, purple, or red veins in red-fruited varieties.  In some cases, the growers noticed poor vigor and quality in their vineyard blocks.  Some growers started harvesting fruit from healthy (green leaves) and diseased (red leaves) vines separately and noted lower brix counts on grapes harvested from vines displaying red foliage.  More conservative growers are not harvesting grapes from heavily red foliage colored vines at all. 

To the naked eye, Red Blotch symptoms can be confounding...Read More!

Eurofins STA’s new eLIMS Database
19 August, 2011

On August 1, 2011, we started entering and reporting all Plant Health Services samples in the  new eLIMS (eurofins Laboratory Information Management System) database.  Before this transition, we spent nearlya year testing and customizing it to suit not only our needs but our clients’ needs as well. 

With this transition we implemented a few changes.  Our order form is now called an "Acknowledgement of Receipt or AOR", and our Certificate of Analysis is called an "Analytical Report or AR".  Both are uniquely formatted and contain the pertinent information our clients need, with the added benefit of electronic delivery.  The ability to send these documents electronically has significantly reduced the time between data entry and reporting. The email is handled directly out of eLIMS avoiding any potential mistakes in transmission.  By taking advantage of the technology we can email an Acknowledgement of Receipt immediately after our clients’ samples are entered and Analytical Reports to our clients instantly after reporting results. 

No more lost faxes or illegible copies, and no more waiting for the originals in the mail!  If you would like to receive these documents electronically, all we need is your email address.  We can send them to one or many recipients.  Give us a call or send us an email at stalabs@eurofinsus.com. We are happy to get this set up for you.
 

Each client can have one main recipient.  All additional recipients must be set up to receive copies.  Currently, when an AOR or AR is emailed to a client, eLIMS will first email it to the main recipient.

We would also like to announce the availability of Eurofins Online Reporting (EOL)With EOL, our clients are able to create and maintain their own user accounts, which will allow them to see the status of their samples as well as Analytical Reports for results on completed samples.  Our clients can also view the history of their samples.  For more information, please visit the EOL main web page or sign up today!

We hope our clients are as happy with our new database as we are and hope they will continue to provide feedback as we move forward.  Feedback is very important to us and we will take each and every comment into consideration for continued improvement. 


Please check our website for important updates on our testing technology: http://www.stalabs.com/products-services-grapevine-testing.html
 
You can always call me with any questions or comments at our California lab (408) 846-9964

For grapevine growers, a positive test result can open a Pandora's Box. We offer custom disease eradication services that use modern technology to completely eliminate diseases from stock plant material. By detecting pathogens at the earliest phases, we help you mitigate losses by stopping diseases that can continue to spread and destroy existing plant stock. We also provide tissue culture propagation of grapevine stock to grow healthy and vigorous plantings. For your benefit, all Eurofins BDI client materials, diagnostic results and reports are handled in full confidentiality.

Grapevines are expected to live over 80 years so it makes good business sense to pay close attention to the organization of your grapevine mother blocks and certify your planting material is free of known and detectable pathogens.

We offer seasonal vineyard surveys that combine state-of-the-art testing with on-site consulting from our leading expert pathologists. Working closely with you in the field, we discuss your specific testing needs, recommend sampling strategies to more accurately detect the presence of pathogens in spite of low concentration or erratic distribution in the vine, and provide field or nursery operation inspections to assess grapevine health.

Spring Field Survey
Comprehensive inspection of vineyard. Looks specifically for vine decline symptoms associated with virus infection (viruses included in HealthCheckTM Panel B). The half-day visit includes training of professional and field personnel to look for specific symptoms and collection of samples for virus and other pathogen testing.

Summer Field Survey
Comprehensive vineyard inspection. Looks specifically for Pierces Disease symptoms. The three-hour visit includes training of professional and field personnel for collection of pathogen testing.

Fall Field Survey
Comprehensive full-day or half-day visit. Looks specifically for symptoms associated with virus infection (viruses included in HealthCheckTM
Panel A). The visit includes inspection of vines, training of professional and field personnel to look for specific symptoms and collection of samples for virus and other pathogen testing. Vines will be marked for future sampling/testing.

Winter Field Survey
Training of personnel to collect samples for testing viruses in HealthCheckTM Panel A. A methodology is applied to assure that a representative number of samples are collected from vines used to generate grapevine cuttings. A system for tracking mother-daughter plants will be applied to correlate sample data with each batch of grapevine cuttings.

Eurofins BDI Plant Health Services provides state-of-the-art testing for the diagnostics and detection of major grapevine pathogens. Different methods including microbiological culture, ELISA, PCR, RT-PCR and/or Immunocapture RT-PCR are used for specific diagnostics.

We have grouped the pathogens into different panels (A, B, CG, PD, Fungal) based on sampling/testing requirements. Research has shown that there is seasonal variation in the concentration of grapevine pathogens. Furthermore the distribution of pathogens follows a pattern and certain pathogens can be found in higher concentrations in different parts of the plant.

Our laboratory has developed sampling methods that takes into consideration the seasonal variation and pathogen location to optimize the detection of harmful pathogens. To assure accuracy of results, when multiple diagnostic methods are available, submitted samples will be tested by at least two independent methods. Eurofins BDI Plant Health Services offers custom disease diagnostics, please contact Raquel Salati, Ph.D. at raquelsalati@eurofinsUS.com or (408) 846-9964 for specific sampling instructions.
