|Over the last week I have been seeing areas of lodging and general weaker stalks in some corn fields. Lodging is the process where a corn stalk breaks below the cob. There are multiple factors that contribute to lodging:Stalk Cannibalization
Prior to black layer, the corn plant will respond to stress by moving sugars from the stalk and leaves to the ear. This is the plants method of maximizing potential yield. As these sugars are removed, the pith cells which give the stalk strength, break down and result in a weaker stalk which are more prone to lodging.
