Granular 10% disulfoton used at rates of 20 or 30 lb and aldicarb used at a rate of 20 lb active ingredient per acre gave excellent control of 3 generations of birch leaf miners, Fenusa pusilla (Lepeletier), on gray birch when applications were made either Feb. 29 or Mar. 27. Granular 10% phorate applied Apr. 4 at a rate of 30 lb active ingredient per acre and cultivated into the soil in 7-inch hands at both sides of the rows gave good control of the 2nd summer generation of Nantucket pine tip moths, Rhyacionia frustrana (Comstock), on Japanese black pine. No material tested was effective against the 1st summer generation. Granular 10% disulfoton applied May 3 at rates of 10 or 20 lb active ingredient per acre to rock cotoneaster in containers was effective against the spirea aphid, Aphis spiraecola Patch, until at least Aug. 11.
