Washington wine grape growers are invited to learn about the latest phylloxera research findings during the WAVEx webinar scheduled April 20 at 3 p.m. Pacific Time. 

Following new discovery of phylloxera in Washington state in 2019, a coordinated and comprehensive research project to learn about phylloxera was initiated in 2020 by Washington State University. The research, supported and funded by the Washington wine industry, is led by Doug Walsh, Michelle Moyer, Markus Keller and Gwen Hoheisel.

In this free webinar, Moyer will share how the risk map was developed and how to read the risk categories and utilize online phylloxera resources. Walsh will discuss preliminary results of his efficacy trials looking at contact and systemic insecticides for control. One pesticide recertification credit has been requested from Washington and Oregon agriculture departments. The webinar will allow time for questions from the audience.

Washington Advancements in Viticulture and Enology (WAVE) and WAVEx are a series of research seminars and webinars sponsored by the Washington State Wine Commission and WSU. WAVEx is the condensed, shorter webinar series. The events help make wine research findings more accessible to growers and wineries.
