A number of general-use insecticides, including acetamiprid (Ortho Flower, Fruit & Vegetable Insect Killer), carbaryl (Sevin) and malathion, may be used to discourage feeding. See table below for what can be used and the number of days between application and harvest.
** Days to harvest
Carbaryl has a two-day waiting period between spraying and harvest on sweet corn and a three-day waiting period on peaches. There is a seven-day waiting period for Sevin on blackberries, so malathion, with a one-day waiting period, may be a better choice. Acetamiprid has a 7 day waiting period on peaches and a 1 day waiting period on blackberries and raspberries. (Ward Upham)
