STA 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 Bio-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. STA Plant Health Services offers custom disease diagnostics, please contact Judit Monis, Ph.D. at info@stalabs.com or (408) 846-9964 for specific sampling instructions.
