WSU & Washington State Grape Society Viticulture Field Day

August 11 @ 8:00 AM - 11:00 AM


Join this outdoor educational event on August 11 at the main campus vineyards at WSU’s Irrigated Agriculture Research and Extension Center in Prosser. Topics will include assessing coverage and drone spraying, demonstrations of alternative pest management technologies for ozone, heated oil, the Washington wine industry-supported UV-C application, smart spraying, and solid set canopy sprayers/sprayer rate controllers. Registration will close on August 3 or after 80 people register.

This outdoor event will feature a series of four rotations featuring sprayer technologies:

Station 1 – Assessing Coverage and Drone Spraying. Learn about state-of-art on UAV based spraying, including the types of platforms available, what nozzles they use, and their flight speed/altitude attributes (along with swath width). Learn about pertinent FAA and state regulations on drone spraying. This station will include a demonstration with a DJI Agras T20 drone, and attendees can see what the spray coverage looks like in a full-canopy vineyard. Presented by Lav Khot, Washington State University.

Station 2 – Non-residue spraying – Ozone, Oil and UVC. Come and see these alternative pest management technologies in action! This station will demonstrate machines that apply ozonated water, heated horticultural oil, and UVC light. It will present information on the logistics of the machines and their efficacy for disease management in vineyards. Presented by Lexie McDaniel and Jake Schrader, Washington State University.

Station 3 – Smart Spraying & Solid Set Canopy Sprayers. Different ways to apply pesticides, through the “Intelligent Sprayer” and Solid Set Canopy Delivery System will be explained, including how they work and how they can be used to improve spray application. Both systems will be demonstrated in-field so participants can see the differences in how they function, including a visualization on total products that are used, and what their spray coverage is with these two application approaches. results will be discussed. Presented by Ramesh Kumar and Datta Bhalekar, Washington State University.

Station 4 – Commercial Rate Controllers. VineTech and AgOtter will present information on their sprayer rate controllers, and how they can be used to assist in more accurate pesticide application and monitoring of product use in vineyards for smarter pest management. Presented by Grant DeVries (VineTech), and Dave Nerpel (AgOtter).
