Grape Pest and Disease Management for Western Washington

Raising wine and table grapes in Western Washington can be both rewarding and challenging. Rewarding for the wonderful flavors this region's climate and unique soils can foster, and challenging for the myriad pests and diseases that find it a welcoming environment as well. Learning how to deal with the challenges is key to successful harvests.

Join us Saturday, March 19, 2016 for an immersive workshop on Grape Pest and Disease Management for Western Washington with Dr. Michelle Moyer, Assistant Professor and Extension Viticulturist and Gwen Hoheisel, Regional Extension Specialist from the WSU Viticulture and Enology Program in Prosser, WA. Location is the Stillaguamish Grange, 6521 Pioneer Hwy, Stanwood, WA.

Sponsored by the WSU Viticulture and Enology Program, WSU Snohomish County Extension, and WSU Extension you'll learn how to identify friends and foes and then devise a strategy to minimize their impact. We will cover both organic and conventional approaches. Full day participants will receive one copy of the new WSU Extension 2016 Grape Pest Management Guide and an opportunity to qualify for up to 5 WSDA Pesticide Certification Credits.

Morning session …..9:00 am – Noon
We'll cover Brown Marmorated Stink Bug and Spotted Wing Drosophila biology and management, followed by hands-on time with microscopes to take a closer look at identifying these insects . Emphasis will be placed on distinguishing invasive species from native and beneficial species.

Then we'll cover Sprayer Best Practices where you'll gain an understanding of the environmental conditions that influence spray efficacy and drift, along with a discussion on how equipment choices and maintenance can influence any pest management program. Before lunch, we'll end with a hands-on session and learn how to properly calibrate backpack sprayers including how to change sprayer nozzles, maintain consistent pressure, and determine volume-per-acre necessary. Includes a discussion on whole-canopy (disease) vs. spot spraying (insects and weeds). Anyone raising soft fruit will find this session especially valuable, not just those raising grapes. Morning session is eligible for 2 WSDA Pesticide Recertification credits.

Afternoon session …..1:00 pm - 4:00 pm
After lunch we'll devote the afternoon to Designing Grapevine Disease Management Programs with a special emphasis on Powdery Mildew and Botrytis Bunch Rot disease biology and management strategies. Discussions will focus on integrating chemical and cultural practices for optimal control with an eye to modes-of-action rather than specific chemicals so it can be adapted to both organic and conventional management strategies.

We'll work in small groups to practice designing a program you can put to use this season. Each group will be invited to share their strategies, be evaluated for content, feasibility, and cost. After joint discussion, the group with the most sustainable strategy will win a prize! Morning session is eligible for 2 WSDA Pesticide Recertification credits.

Space is limited and pre-paid registration by March 17 is required. Cost for either morning or afternoon sessions is $20 per person. Both sessions plus box lunch and one copy of the WSU Extension 2016 Grape Pest Management Guide is $45.
