eOrganic is presenting a free, one-hour webinar on biological control of whiteflies in squash. Oscar Lilburd will introduce the topic of biological control in vegetable crops using predators and parasitoids, including predatory mites and insect predators. Lorena Lopez will then discuss the use of companion plants in organic vegetables, focusing on enhancing and conserving biological control. She will also discuss predatory mites behavior in organic squash planted adjacent to sweet alyssum (companion plant). Then, Dr. Lilburd will talk about the effect of using pesticides labeled for organic use on these predators and how long after plots have been sprayed that these predators can be released back into the field.
