Digital Crop Doc
The UMN Extension crops team is launching a new program to help you with disease diagnosis in several crops:
- Small grains
Visit the Digital Crop Doc, where you can tell us more about your field situation and submit photos. After you submit the form and 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.
