Digital Crop Doc
The UMN Extension crops team is launching a new program to help you with disease diagnosis. Visit Digital Crop Doc, tell us more about your field situation and submit photos. One of our team members will contact you with a diagnosis, a request for more information or a suggestion to submit the samples to a plant disease clinic.
There is no cost to use this service! Your submissions will help alert us to new or emerging field crop diseases throughout the state. This, in turn, will help us focus our research and education programs to meet the needs of Minnesota crop producers and other ag professionals.

Corn rootworms are adaptive, changing to meet shifting production practices, technology, and climate. With the development of resistance to Bt-rootworm corn, corn rootworms now pose a challenge for most corn growers.
The purpose of the IPM (Integrated Pest Management) podcasts is to alert growers, ag professionals and educators about emerging pest concerns on Minnesota field crops - including corn, soybean, small grains and alfalfa. We also review recent pest trends and research updates.
