Abstract
Abstract This experiment was conducted in a 3-yr-old orchard with the trees planted at a spacing of 8 × 5 ft. The experimental design was seven 0.17 acre plots. Insecticides were applied on 15 Jun with a Rears Pak-Blast airblast sprayer delivering 100 gpa. Aphid control was evaluated by counting the number of aphids on 8 randomly selected tagged shoots per treatment pre-application and 2 and 10 d postapplication.
