Crown rust in oats

Flown by Mark Carter, Agriculture & Natural Resource Educator, Purdue Extension

A producer noticed discoloration in his oats and called the local Purdue Extension office for advice. The oats were planted as a cover crop to be used as forage, so we contacted Dr. Keith Johnson, the Extension forage specialist. He and Extension educator Mark Carter determined the issue and flew the field to inspect the widespread damage. The disease is evident in the RGB map and is even more apparent in the VARI map. VARI stands for Visible Atmospherically Resistant Index and is designed to work with RGB sensors to identify crop stress and generate variable rate prescriptions. Plant samples were also collected and crown rust was confirmed by Purdue Pest and Plant Diagnostic Laboratory.
