Tar spot in corn
Flown by Crystal Van Pelt, Agriculture & Natural Resources Educator, Purdue Extension – Steuben County
Tar spot was discovered at a Purdue irrigation research plot and monitored by Darcy Telenko, Extension plant pathology specialist, and Lyndon Kelly, Extension irrigation specialist from August through October. The plot was flown mid-October to observe disease impact. Plants not under the pivot irrigation system were decimated while the plants under the system were severely damaged. Collecting data earlier in the season and over more fields will help in future years to help us understand the disease progression.
