Abstract
Abstract Test plots were located at Columbia View and Smith Tract orchards of the Tree Fruit Research Center, Wenatchee. The plot at Columbia View consisted of Elberta and Hale varieties. The Smith Tract plot consisted of a mixture of several early and late maturing varieties. Plots were arranged in a completely random design with 4 single tree replicates per plot. Plots were sprayed to the point of drip with hand guns at 400-500 psi. Pretreatment counts were made by examining each tree and recording the number of infested twigs. Post-treatment counts were conducted in the same manner.
