Stalk lodging in corn occurs when the stalk weakens and breaks at some point below the ear. This results in harvest losses and slows down harvesting considerably. Stalk rots occur for a variety of reasons, ranging from disease organisms and environmental factors.
It is important to check sorghum fields for stalk rot diseases prior to harvest. Even in fields where lodging is has not yet occurred, producers should be prepared to deal with stalk rot issues. Symptoms generally appear several weeks after pollination when the plant appears to prematurely ripen.
