| Abstract/Contents: | "Rhizoctonia solani-incited leaf spot and blight is a major disease of tall fescue (Festuca arundinacea) in the sections of the North American continent characterized by warm, humid summer months. In greenhouse-based studies, tall fescue plants grown under nutritional regimes of either high imbalanced N or high balanced N, P, and K were more susceptible to the disease than those grown under either low imbalanced N or low balanced N, P, and K. Plants grown at soil moisture regimes of continuous 1/3 atm, and cyclic 1/3 → 15 atm → 1/3 atm, respectively, were not altered in their apparent susceptibility to the disease. In environment control chamber-based studies, it was determined that the optimum conditions for infection were 48 hours of continuous free moisture on the leaf surface and an air temperature of 32 C, while the optimum temperature for colonization was 26 C." |
