Mite Trial, 1986

ABG-6I62HV (1.5% wt/wt) was applied to an apple block at Steeles Tavern, Va., at 2 rates, and was compared with Apollo 50 SC. The following treatments were applied 8 Apr at the pink stage of bud development: ABG-6162HV at 60 g (AI)/acre, ABG-6162HV at 90 g (AI)/acre, and Apollo 50 SC at 85 g (AI)/acre. The first 2 treatments were repeated 5 May at petal fall. Each plot was about one-quarter acre. Applications were made with a truck-mounted Swanson airblast sprayer, calibrated at 59 gal/acre (176 gal/acre dilute equivalent). One plot was an untreated control. Mites were sampled from 4 trees/treatment. One 20-leaf replicate was collected from each tree on each sampling date. Mites were removed from leaves with a leaf-brushing machine and counted under a binocular microscope.
