Disease severity and insect defoliation training tools

By Daren Mueller–Iowa State University Extension and Outreach

The Crop Protection Network’s new online tool can help with identifying various crop diseases and their severity.

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.

“The Crop Protection Network hopes this new tool can help people make the most accurate estimations possible,” said Daren Mueller, extension plant pathologist with Iowa State University Extension and Outreach, and co-director of the Crop Protection Network. “We want to offer as many tools as possible to help with scouting efforts and ultimately help make the best management decisions.”

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.
