G79-429 Tan Spot Disease Of Wheat (Revised June 1993), John E. Watkins, Robert N. Klein, Eric D. Kerr

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes the development of tan spot disease in wheat and gives recommendations for controlling it by means of crop rotation, fungicides and good crop residue management.

Tan spot, caused by the fungus Pyrenophora tritici-repentis, is a major leafspot disease of winter wheat in the Great Plains of North America. It has become an increasing problem in wheat cropping systems using conservation tillage.
