Exclusion Netting Helps Prevent Spotted Wing Drosophila in Berries

Brambles: Organic Production
New York berry growers collaborating with Cornell University researchers are reporting success in using exclusion netting to prevent spotted wing drosophila (SWD) infestations. A paper published in Crop Protection documents that in testing over the past few years, early-season placement of exclusion netting was effective in protecting raspberries from SWD. One grower has avoided pesticide use for six years, with less than 1% incidence of SWD. She notes that the cost of the exclusion netting is lower than the cost of pesticides. The netting is attached to a frame that surrounds the berry crop. Producers must be prepared to deal with infestations that can occur from workers moving in and out of the exclusion.
