Hello, all. After this morning’s invited speaker talk (OPVC Annual Grower Meeting – see below for link to watch it), I thought it might be helpful to assemble some existing resources we have about Delia spp. maggots in the PNW. Browsing these links could help you better prepare for the planting season. Also feel free to leave a comment with any specific concerns or impact you’ve experienced. Thanks to Dr. Nault for a great presentation this morning!
