Detection of GRBV-infected vines with LAMP (loop mediated isothermal amplification)
Lecture and Workshop
Join the Sonoma County Vineyard Technical Group for a Hands-On Workshop: Visual and Molecular Detection of GRBV featuring Dr. Monica Cooper (UCCE Napa County Viticulture Farm Advisor) and her team—Hannah Fendell-Hummel, Alice Masuyer, Greg Siewert, and Tatiana Warke—focused on the visual and molecular detection of Grapevine Red Blotch Virus (GRBV) using LAMP (loop mediated isothermal amplification).
Location: Sonoma County Farm Bureau
Date: May 15, 2025

What to Expect:
A. Lecture:
Learn to recognize characteristic symptoms of red blotch in red wine cultivars, the best time of year to monitor, and how to distinguish GRBV from other disorders. The team will also walk us through molecular detection tools—when and how to use qPCR and LAMP to confirm what you’re seeing in the field.
B. Workshop:
Roll up your sleeves and get practical. You’ll collect tissue samples, label and track them properly, and run a LAMP assay step-by-step. We’ll cover when to test, how to interpret results, and the nuances of sampling, especially for asymptomatic vines like Sauvignon Blanc or when multiple viruses are in play.
