Abstract Treatments were applied to 4 single-tree replications of 33-yr-old trees in a randomized block design. Applications were made with a Swanson DA500A airblast sprayer, which traveled at 3.86 km/h and delivered 935 liters/ha. Other materials applied separately to all treatments were Bayleton, Benlate, Bordeaux mixture, Captan, Lannate, Manzate 200, Polyram, Sevin, and Streptomycin. 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
