This report summarizes the pesticide assessment for corn and soybeans in the Delta States. Without insecticides, corn rootworm larvae and other soil insects would cause substantial corn yield losses, while corn earworms or loopers would cause the greatest losses to soybeans. The loss of fungicides would result in corn yield losses from seed rots and seedling blights and soybean losses from foliar diseases. The loss of nematicides would cause soybean yield losses. Among the herbicides, the loss of triazines would cause the greatest corn yield losses, while either the phenoxys or bentazon would cause the greatest soybean yield losses. 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.
