LEXINGTON — Historically, Stewart’s wilt of corn has resulted in losses for corn producers; however, this disease now only occurs occasionally in Kentucky. Nevertheless, when it does occur, it can limit yield directly through stand reductions and the production of fewer and smaller ears. In addition, infected plants are more susceptible to stalk-rotting organisms, which can result in indirect losses from this disease. Stewart’s wilt occurs on sweet corn, popcorn, and field corn.
