Abstract

Abstract Treatments were applied to a completely randomized block. Each treatment consisted of single trees replicated 4 times. Sprays were applied 30 Apr at pink (P), 10 May at petal fall (PF), 24 May, 5 Jun, 17 Jun, 30 Jun, 12 Jul, 24 Jul, 7 Aug, 19 Aug and 3 Sep 85. Sprays were applied in 190 gal of finished spray per acre by a Bean orchard sprayer. Evaluations were made by examining 100 apples per replication for injury and categorizing injuries by their respective pest. A single mite count was made in midseason by collecting 50 leaves from each replication and brushing them in a mite brushing machine. Resulting plates were examined using a stereo binocular microscope recording numbers of ERM and predaceous mites on each plate.
