Wheat stripe rust, caused by the fungal plant pathogen Puccinia striiformis f. sp. tritici, has been an increasing problem in the central Great Plains and areas of the upper Midwest due to milder winters (Chen, 2005). Since 2000, stripe rust has become an increasing concern on winter wheat in the Midwest. In Wisconsin over the last four seasons, we have observed consistent stripe rust pressure on some varieties throughout the wheat production area of the state. In 2016, some cultivars were hit very hard by this disease. Because of the consistent occurrence of stripe rust over the last few seasons, it is reasonable to expect continued pressure from this disease in 2017.
