| Abstract/Contents: | "Brown patch caused by the fungus Rhizoctonia solani is a major problem on tall fescue lawns grown in the transition zone. While resistant cultivars are available, inconsistency in evaluations of these cultivars often results in variability of the resistance response. Two possible reasons for this inconsistency are the variability brought on by using a subjective visual rating system when evaluating disease resistance and that Rhizoctonia zeae, a fungus whose symptoms are nearly identical in appearance to R. Solani, is causing disease symptoms. R. zeae symptoms may easily be mistaken for Brown Patch and are not readily discenable in the field. The objective of this study was to develop a method by which Festuca arundinacea germplasm could be more effectively screened for brown patch resistance using digital analysis to evaluate disease severity of both R. solani and R. zeae. Conetainers containing 'Kentucky 31' were grown to maturity, inoculated with either R. solani or R. zeae, then maintained at a temperature ideal for development of each pathogen. Conetainers were then evaluated visually using a typical 1-9 rating scale, digitally using the entire pot, and digitally using individual leaves. These methods will be analyzed using ANOVA and results will be presented." |
