Sonoma County Grape Day is an annual program presented by University of California Cooperative Extension (UCCE) that provides research-based information on issues important to the production of coastal winegrapes.
Keynote speaker this year is Dr. Tom Collins, from Washington State University who will address his research projects related to smoke taint. Specifically, the composition of smoke from different fuel sources, simulated wildfire exposure to vines in hoop houses and his evaluations of primarily wines that have been affected by actual wildfires, including wines from Napa, Sonoma and Washington.
UC Davis Plant physiologist Dr. Kaan Kurtual, will address research results that illuminate how leaf area and crop load control affects vine physiology and fruit ripening. Three speakers will address pest management topics applicable for CE units: grapevine rootstock performance in site infested with the dagger nematode that vectors grapevine fanleaf virus, weed control and Pierce’s disease.
Breakfast and check-in starting at 7am, program starts at 8am. Pre-register for $42 if paid online with credit card or by check by February 6. Registration AT THE DOOR is $47 (cash or check only).
