When Spotted Wing Drosophila became a problem in New Jersey blueberry fields two years ago, Bobby Galletta of Atlantic Blueberry Company was ready to defend his crop from the destructive vinegar fly that lays its eggs in ripening fruit…”There are only five classes of insecticides that work well against SWD,” according to Cesar Rodriguez-Saona, an entomologist with Rutgers University’s Philip E. Marucci Center for Blueberry and Cranberry Research and Extension in Chatsworth. “So, we are recommending that growers rotate insecticides with different modes of action in their spray schedule so that the insect does not develop resistance to any one class of insecticide.”
