UC Ag Experts Talk: In-House Diagnostics for Disease Management: LAMP for Red Blotch in Grapevines

Dr. Monica Cooper presented an introduction to grapevine red blotch virus (GRBV) ecology, physiological impacts, symptoms, and management. She discussed the Loop mediated isothermal amplification (LAMP) tool and described how to collect, process, and run samples of grapevine tissue to detect GRBV in grapevines. Practical applications of a statistical sampling process to identify patterns of GRBV incidence and spread in asymptomatic cultivars were discussed. The webinar was recorded on November 12, 2025 and targeted to growers and pest management professionals.
