Stripe Rust Pustules on a Winter Wheat Leaf

Brian Mueller, graduate student in my program, observed the first pustules of stripe rust on winter wheat in Wisconsin in 2015 (see attached image). These were found in Sharon, WI in the UW wheat variety trial on June 4. This location is west of Janesville, near the Illinois border. Pustules were located in just one plot on a single variety. No pustules were identified in other plots. We will continue to monitor the wheat rust situation over the next couple of weeks.
