Some fruit growers in Virginia experienced difficulty in controlling leafhoppers on apple in recent years. Treatments were applied to runoff with a Bean hydraulic sprayer operating at 400 psi on 8 May. Test trees were 4 year old 'Ace Red Delicious.' Plots (single trees) were arranged in a randomized block design. Each treatment and the control was replicated 4 times. The total number of live leafhoppers on 20 leaves from each replicate was determined on 9 May.
