Abstract
The systemic insecticides carbofuran mephosfolan and disulfoton were evaluated in the field for conrol of some insects on soybeans when the insecticides were applied in seeding-pits at the rates of 4.6, 9.2 and 13.8 mg(a.i)/pit at the planting time. Control of the soybean aphid (Aphis glycines Matsumura) and the two-spotted spider mite (Tetranychus telarius(L.)) on soybeans was obtained for about 2 to 3 months, but their treatments were ineffective against the soybean moth (Grapholitha glycinivorella Matsumura). For the control of aphids and mites, disulfoton was better than carbofuran and mephosfolan. The insecticides slightly reduced the soybean stands, while the low-dose treatments of carbofuran slightly increased the stands. Carbofuran and mephosfolan caused severe phytotoxicity at the early stages, but disulfoton showed slight or negligible phytotoxicity. The phytotoxic symptoms in carbofuran and mephosfolan treatments were shelving the large number of brown or black-brown spots on the cotyledon and the first-leaves, and in addition to that showing necrosis along the leaf-margin. The symptoms in disulfoton treatments were slight withering along the leaf-margin of the first-leaves. In spite of good control of aphids and mites, there were no differences in soybean yield.
