Monitoring Corn Fields for Stalk Quality Problems

By Dairyland Seed Agronomy Team

Many different stresses to the corn plant can lower stalk quality, with the result that stalk problems occur in some fields each year throughout the major corn-growing areas of North America. 
 
Drought stress, reduced sunlight, insect and disease pressure and hail damage are stresses that can result in poor stalk quality. Even good growing conditions can lead to stalk problems, when followed by a less favorable environment. 
 
Many additional factors, including cropping history, soil fertility, hybrid genetics, and microenvironment effects can heighten the problem in particular fields. Growers should monitor their fields as harvest approaches, to identify stalk quality problems and prepare to harvest before field losses occur. 
 
Our Crop Bulletin "Monitoring Corn Fields for Stalk Quality Problems" discusses the causes and management of stalk rot problems in corn.
