PESTICIDE ASSESSMENT OF FIELD CORN AND SOYBEANS: SOUTHEASTERN STATES

This report summarizes the pesticide assessment for corn and soybeans in the Southeast. Without insecticides, corn rootworm larvae and other soil insects would cause substantial corn yield losses. Corn earworms would cause the greatest losses to soybeans. The loss of fungicides would result in corn yield losses from seed rots and seedling blights. The loss of nematicides would cause substantial losses to both corn and soybeans. Among the herbicides, the loss of triazines would cause the greatest corn yield losses, while the loss of postemergence treatments, including bentazon, would cause the greatest losses in soybean yields. This report includes pest rankings, estimates of acreages treated with pesticides or other pest management practices, and estimates of pest losses with and without pesticide use, for insects, diseases, nematodes, and weeds
