About the CPN

The Crop Protection Network (CPN) is a multi-state and international collaboration of university and provincial Extension specialists, and public and private professionals that provides unbiased, research-based information to farmers and agricultural personnel. Our goal is to communicate relevant information that will help in the identification and management of field crop diseases.

The CPN produces collaborative outputs on important diseases affecting field crops in the United States and Canada. All publications are available as downloadable PDF files and in a mobile-friendly format. This website is a work in progress, and new publications will be added as they are produced.

This effort is currently supported by the North Central Soybean Research Program (NCSRP), the United Soybean Board (USB), and the Grain Farmers of Ontario (GFO). Institutions partnering with the CPN are listed below. All Land Grant Universities involved are also supported by the United States Department of Agriculture.
