Apple, Mite Control With Savey, 1986

Treatments were applied to 4-tree plots in a completely randomized design consisting of 5 replicates/ treatment. Each plot contained one each of the cultivars Delicious, Golden Delicious, Stayman, and Rome Beauty. Sprays were applied as alternate side applications with a Myers Mity Mist sprayer calibrated at 50 gal/acre, driven at 2 mph. Spray dates were as follows: 25 Apr, 8 May, and 23 Jul. A routine schedule of fungicides and insecticides (Dithane M-45, Benlate, Guthion, Lorsban, Phosphamidon, Systox and calcium chloride) was maintained throughout the experiment. Effectiveness of treatments on ERM and TSSM was evaluated by counting mites several times during the season on samples of 25 leaves/ tree, 125 leaves/treatment (cv Delicious). The predator S. punctum was observed by making 3 min counts of adults and larvae around the periphery of ‘Delicious’ trees. Mite pressure was light.
