Management of Obliquebanded Leafroller Damage and Insecticide Resistance With a Biorational Insecticide Program

Abstract

During the spring of 1999 prior to bloom, OBLR were collected from 5 commercial orchards in which biorational insecticide programs were begun to assess the baseline susceptibility of each population to the commonly used organophosphate insecticides, azinphosmethyl and chlorpyrifos.
