Stem Borer - Agronomic impact

Yield loss from larval feeding within the plant is usually not significant. Most of the damage occurs when the plant stem is cut and plants fall over. This occurs soon after the plants have matured. Yield loss because of lodging is most severe on early-planted soybeans, non-rotated soybeans, and where soybeans are not harvested soon after maturity.
