Abstract
Abstract This test was conducted in a 0.6 acre block of 11-yr-old 'Topred' trees on MM106, which measured 14 ft in height and 10 ft in width and were planted at a spacing of 14 × 14 ft. The experimental design consisted of 4 single-tree plots in a randomized block design, with each replicate surrounded by at least one unsprayed tree on each side. Acaricides were applied to runoff on 19 Jun and 17 Jul with a handgun attached to a Durand-Wayland 100 LTS sprayer operated at 100 psi. Each tree received approximately 1.5 gal of spray (ca. 333 gal/acre). Other materials applied separately to all treatments were Agristrep, Benlate, Captan, Dimethoate, Dithane Z-78, Guthion, Lannate, Lorsban, Nova, Oil, Penncap-M, Polyram, Rubigan, Sevin, Solubor, Topsin-M, and Zineb. European red mite control was evaluated by sampling 25 leaves from the periphery of each tree, removing mites with a mite-brushing machine, and counting active stages with a binocular microscope. The effect of treatments on S. punctum was determined by counting adults and larvae observed in 3 min counts around the periphery of test trees.
