| Abstract:
A program to control arthropod pests of pear in southern Oregon (Codling Moth Areawide Program, CAMP) utilizing codling moth (CM) mating disruption and three horticultural spray oil applications during the foliar season was initiated in 1994 on 32 hectares, expanded to 121 hectares in 1995 and to over 162 hectares in 1996. During the first three years of the program the use of organophosphates have been reduced by 80%, 72% and 73% respectively and overall synthetic pesticide use by 79% to 90%. Besides reducing pesticide use, the program has continued to achieve suppression of primary and secondary pear pests, maintaining damage at a level of 1.5% fruit downgrading, while lowering the cost of arthropod control by about $447–$550 per hectare. | |
