Over one million acres of soybean are usually grown in Tennessee, more than any other crop. Average yields typically range from 20-40 bushels per acre, with 5-10% yield loss being attributed to insect injury. Estimated, statewide insect control costs usually range from $5-10 per acre. Most soybeans are grown in the Western and Middle Tennessee (production map). A number of arthropods may cause economic damage to soybean, but stink bugs, corn earworm, three-cornered alfalfa hoppers, and a complex of defoliating insect pests are the most common pests. The following publication provides treatment threshold and insecticide recommendations for common insect pests in soybean.
