Abstract Test materials were applied to 16-year-old apple trees on August 5 at Monmouth, Maine, as dilute sprays with a hand gun from a hydraulic sprayer operating at 300 psi and at a rate of ca 300 gal per acre. Polyram 80W (1 lb/100 gal) and Benlate 50W (2 oz) were sprayed on the trees at 2-3 week intervals from mid-June to mid-August. There were no tank-mixtures of insecticides with the fungicides. There were 2 single-tree replications per treatment. A randomized complete block design was utilized with 1 Mcintosh and 1 Spartan cultivars per treatment. Prior to treatment, 5 succulent terminal vegetative shoots were tagged around the periphery of each tree, at a height of 3 to 6 feet. Evaluation was based on a count of all live aphids found on the distal 4 unfurled and 1 furled leaves and on the stem included by these leaves on each tagged termi-al shoot. Aphid population pressure was not severe.
