|Potential benefits of powdery mildew resistant grapevines||
Recent research from the UC Davis Department of Agricultural and Resource Economics evaluated the potential economic benefits to California of powdery mildew resistant grapevines. (See newsletter link below).
As a follow-up to this study, the research team is collecting information on grower preferences for specific traits. We would appreciate if you could take a few minutes to respond to their survey questions: https://okstatecasnr.az1.qualtrics.com/SE/?SID=SV_5AwMOELdrMZ9xJ3

|Monitoring Guide for Western Grapeleaf Skeletonizer||
On June 24, 2015, staff of the Napa County Agricultural Commissioner found one male Western Grapeleaf Skeletonizer in a pheromone-baited trap in a vineyard on Tubbs Lane in Calistoga.
UCCE Advisors Lucia Varela and Monica Cooper developed a "Monitoring Guide for Western Grapeleaf Skeletonizer" so that vineyard owners, growers and workers could familiarize themselves with the pest's life stages and feeding habits.
Please use the newsletter link below to access the Monitoring Guide (English and Spanish versions).
If you find this pest or feeding damage in Napa County please contact the office of the Agricultural Commissioner: 707-253-4357, email@example.com OR contact UC Cooperative Extension: 707-253-4221, firstname.lastname@example.org
