Grapevine red blotch-associated virus (GRBaV) is a major threat to the wine industry. GRBaV infections compromise crop yield, and cause a significant reduction in sugar, uneven ripening, or failure to ripen, resulting in off flavors and berry chemical composition, which affects the flavor and aroma properties of must and wine. Visual diagnosis is often unreliable due to several confounding abiotic and biotic factors, including similarities with leafroll disease symptoms. To date, no antibody based detection methods for GRBV are available on the market.  Therefore, PCR-based assays are recommended for the accurate diagnosis of GRBV infection.
