| Abstract:
A large-scale demonstration to control arthropod pests of pear (Pyrus communis) in southern Oregon was conducted from 1995 through 1999. The project used orchard monitoring along with mating disruption for control of codling moth (Cydia pomonella L.) and three 1% v/v applications of a narrow-range petroleum spray oil during the foliar season. By these methods, we have been able to reduce organophosphate (OP) use by an average of 66% over the five years of the project and overall synthetic pesticide use by 74%, while successfully suppressing primary and secondary pear pests. Damage from all pests averaged 1.92% fruit downgrading over the five year period, while lowering the cost of arthropod control by an average of $ US 519/ha. | |
