Six windbreaks in west central Oklahoma were surveyed four times in one year for diseases and decay fungi associated with trees in each windbreak. The most severe diseases were Ganoderma root rot and Thyronectria canker on honeylocust, Phellinus pini root rot of Austrian and ponderosa pines, Cytospora dieback of cottonwood, and Phellinus robineae stem decay of black locust.
