Abstract

Abstract Treatments were applied to a completely randomized block. Each treatment consisted of single trees replicated 4 times. Sprays were applied in 123 gal of finished spray per acre by a Bean orchard sprayer. Sprays were applied on 27 Apr at pink (P), 13 May at petal fall (PF), 28 May, 10 Jun, 24 Jun, 3 Jul, 16 Jul, 29 Jul, 12 Aug, 23 Aug, 5 Sep and 19 Sep. Evaluations were made by examining 100 apples per replication for injury and categorizing injuries by their respective pest. RAA evaluations were made using a 3-min sample search. 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.
