  4. Full Group Presentation – Phylloxera Identification and Response.  Scout, dig, and diagnose with us! Learn about identifying vineyard symptoms of a potential phylloxera infestation, and how to scout to confirm the presence (or not!) of this insect.  We will also discuss best-management practices for limiting phylloxera spread both during the growing season, and during harvest.  Presented Gwen Hoheisel and Michelle Moyer, Washington State University.
