Overestimating leaf disease severity and insect defoliation is as easy as overfilling your plate at a potluck. Crop scouts now have a new tool to put estimates on a realistic diet.
This free, interactive activity lets you judge how much of a leaf is covered by lesions or munched on by bugs. With practice, scouts become more accurate in diagnosing the need for treatments for a variety of corn and soybean problems.
The Disease Severity and Defoliation Training tool was developed by the Crop Protection Network (CPN), a multistate and international collaboration of university and provincial Extension specialists, and public and private professionals. Get your training before heading to the field at severity.cropprotectionnetwork.org.
