Abstract: Farmers reported that 28.5 million pounds (a.i.) of pesticides were applied to soybeans in the Mississippi Valley during 1980. This consisted of 26 million pounds (a.i.) of herbicides, 2.3 million pounds (a.i.) of insecticides, 51,000 pounds (a.i.) of nematicides, and 201,000 pounds (a.i.) of fungicides. Pesticide acre-treatments totaled 31.9 million and consisted of 28.4 million with herbicides, 2.8 million with insecticides, 68,000 with nematicides, and 721,000 with fungicides. The primary herbicides were alachlor, bentazon, metribuzin, and trifluralin. The major insecticides were carbaryl, methomyl, and methyl parathion. Benomyl was the primary fungicide. Herbicides were applied primarily to control cocklebur, crabgrass, and Johnsongrass infestations. Most insecticides were used for armyworm, cabbage looper, corn earworm, and velvetbean caterpillar control. Fungicides were mainly applied to control brown spot, leaf blight, and pod and stem blight. Coefficients of variation were computed for acres of soybeans treated with specific pesticides.
