Pre-bloom sprays to control the fruit-tree leafroller, <i>Archips argyropilus</i> (Walker), and the eye-spotted bud moth, <i>Spilonota ocellana</i> (Denis & Schiffermuller), were applied in an apple orchard where no insecticides have been used for 6 years. The phytophagous mites in the orchard are held under control by predacious phytoseiid mites. Azinphos-methyl at 5 and 2 1/2 lb. 25% W.P. per acre gave excellent control of the two insects when applied at the pre-pink stage. Dormant oil at 6 gal. per acre applied at the l/2-inch green stage was ineffective. Oil at 6 gal. and azinphos-methyl at 2 1\2 lb. did not reduce predacious phytoseiid mites over the untreated control. No phytoseiid mites were found on trees treated with azinphos-methyl at 5 lb. The timing at the effective sprays would not interfere with a program of codling moth control by the sterility method.References
