Roots Ear and Kernel Rots Glossary Diseases reduce yields to some extent every year in corn production.
Diseases also are responsible for reductions in grain and seed quality.
Disease losses vary from year to year, and their occurrence is strongly influenced by weather conditions. The purpose of this booklet is to help corn producers and other professionals in the agriculture industry identify corn diseases and provide general recommendations for disease management. The best disease management strategy can vary depending on each individual situation, so it is wise to seek additional information from extension personnel when you have a disease problem. This publication includes only the diseases that occur on a regular basis in the Midwest and those that occur less regularly but are potentially very damaging when they occur. Many materials can be made available in alternative formats for ADA clients.
