Plum curculio management and spray timing Mark Whalon, Dan Nortman, John Wise, Larry Gut and David Epstein Entomology

Preliminary plum curculio life stage control timing for reduced risk and OP-replacement insecticides

1) Alternate row middle or split spray: Actara can only be used the equivalent of once/season. We recommend two half sprays @5.5 oz. 9-12 days apart, equaling one finished 5.5 oz/ acre. 2) Timing in sweet cherries is approximately 25-50 DD50ºF earlier than tarts.
