Farmers, consultants and university Extension agronomists will all need to be prepared to handle a multitude of problems in the field this year. These problems could include every possible issue encountered in growing corn — problems caused by too much or too little fertilizer, too much or too little water, temperatures too high or low, crust over the planted row, insects, diseases, herbicide drift or carry over, and other things.

To assure plant health and subsequent yield, the cause(s) of these problems should be diagnosed quickly so action can be taken to reduce the problem from becoming worse this year or prevent it from developing next year. Diagnosis of crop problems can sometimes be easy, but it is more often difficult.
