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.
We've compiled a list of the most frequently-used resources, reports, and bulletins used by growers and other affected by SWD.
