"For those of you with phylloxera in your vineyard, your good ol' days of self-rooted vines are probably over," said Doug Walsh, a Washington State University entomologist. Walsh and WSU colleagues are seeking funding for a research project to better understand phylloxera's biology and develop management techniques. WSU extension specialists Michelle Moyer and Gwen Hoheisel shared a presentation on how to recognize phylloxera and its feeding damage.
