AMES, Iowa – Crop scouts and field researchers have a new tool at their disposal to help correctly estimate disease severity and insect defoliation in field crops. The new tool can be found on the Crop Protection Network website. ­

This web tool will help scouts and researchers hone their assessment skills to accurately estimate the amount of a leaf covered by disease lesions and the amount of defoliation caused by insect pests.

Using expert information and interactive activities, the new tool presents several common diseases, along with a corresponding visual trainer and self-practice opportunities for assessing injury caused by each disease.

The Crop Protection Network is a multi-state and international collaboration of university and provincial extension specialists and public and private professionals who provide unbiased, research-based information to farmers and agricultural personnel. The goal of CPN is to communicate relevant information that will help professionals identify and manage field crop diseases and other crop production/protection issues.
