Evaluation of codling moth controls : Dimilin, Novaluron, and Avaunt

Two formulations of Dimilin and novaluron, both chitin synthesis inhibitors, were tested for control of codling moth on pear in a full season program consisting of four applications. Single tree replicates were sprayed with an airblast sprayer. All treatments along with a standard program using Imidan resulted in significant reduction of codling moth damage. The greatest reduction in fruit injury at harvest was seen in the novaluron treatment. In another trial three applications of Avaunt plus oil for control of first generation codling moth were made in an orchard using puffers for codling moth mating disruption. Plot size was 1 acre or greater. In comparing plots where a combination of Avaunt and oil was used to plots where only oil was applied, the addition of Avaunt reduced codling moth injury at harvest by 50% or more.
