ARE at AAEA: Marieke Fenton: 2018 AAEA Extension Competition: Benefits of Virus Screening in California Grapevines

July 31, 2018

Time: Between 8 a.m. – 2 p.m., as assigned on site, Sunday, Aug. 5
Location: Hoover/Coolidge Rooms


This work follows up an evaluation of the economic benefits of screening for GLRaV-3 in grapevines in California. GLRaV-3 is a virus that causes decreased yield and quality in grapes, leading to lower profits for producers. Screening for the virus is low cost when available, but not always utilized. Our results show a net positive outcome from using screened vines in all situations. We discuss how our findings are relevant to producers and nurseries in California, and propose methods of extension to disseminate the information to interested parties.
