PCR (polymerase chain reaction) is a technique that detects specific regions in pathogen genome and amplifies them to visible level.

ELISA(enzyme-linked immunosorbent assay) is an immunoassay where pathogen-specific antibody is used to identify given pathogen's surface molecules.

Microscopic examination is used to identify signs of plant pathogens (fungi or bacteria) on symptomatic plant tissues. This may be done either by using a dissecting scope or a compound microscope.

Culturingis a method that is used to isolate fungi and bacteria from symptomatic plant tissue or soil. Selective or non-selective media may be used. Identification is based on the growth and morphological characters an organism produces on a given laboratory medium. Molecular identification (fingerprinting) may also be used.
