Integrated pest management specialist Frank Zalom, distinguished professor of entomology, UC Davis Department of Entomology and Nematology, and plant pathologist Mysore "Sudhi" Sudarshana with the U.S. Department of Agriculture's Agricultural Research Service, based at UC Davis, organized the webinar. The event is supported by the Regional IPM centers as part of the U.S. Department of Food and Agriculture's National Institute of Food and Agriculture (NIFA).

GRB and the virus associated with it have been confirmed in many major grape production regions of the United States and Canada, said Zalom, the lead author of the newly published Regional Pest Alert on the North Central IPM Center website. Several research teams across North America, Zalom said, “have been intensely characterizing the disease and effects on grapevines, as well as characterizing the virus, its spread and potential management” since the discovery of the virus in 2011.
Zalom cited considerable progress, “but much remains unknown. Speakers representing many of the labs will present their work and what it means for the grape industry.”
“Red leaf symptoms that differed from other known red leaf diseases affecting grape foliage were first noticed in vineyards planted with red wine grape cultivars in Napa County, California, in 2008,” he wrote in the Regional Pest Alert. “A virus now known as Grapevine Red Blotch-associated virus (GRBaV) was subsequently identified in grapevines exhibiting red blotch symptoms in 2011. It is now confirmed that red blotch disease is present in many major grape production regions of the United States and Canada.”
