Downy mildews exclusively belong to Peronosporaceae.In commercial agriculture, they are a particular problem for growers of crucifers, grapes and vegetables that grow on vines. In fields with persistent disease problems, the wheat stubble and other residues should be tilled into the soil to permit disease causing fungi to die out before another wheat crop is planted. Ellen Phillips, Crop Systems Educator at the Rockford Extension Center, reports the disease in northern Illinois wheat fields. Optimum development of powdery mildew occurs between 59 and 71 degrees F and is retarded by temperatures above 77 degrees F. Mildew is more severe in dense stands of heavily fertilized wheat. Summary of Wheat Disease Control Practices • Plant after Oct. 15. • Use recommended resistant varieties. tritici prevailing in China’s Northern Winter Wheat Region (Wang et al.

Control of powdery mildew in wheat is primarily achieved by the application of fungicide and the use of germplasm with disease resistance genes. Tundu disease is often known by names like “yellow ear rot of wheat”, “tundu disease of wheat”, “bacterial rot of wheat ears”, “bacterial spike blight”, and “yellow slime disease”.
