Integrated Pest Management of SWD
Prevention - This is only effective if the pest has not made it to the targeted area. Use sanitation practices to destroy fruit culls. Remove other potential SWD habitat. Promptly remove all non-marketable hanging fruit from your fields. An ounce of prevention is worth a pound of cure.
