| Abstract/Contents: | "The relationship between incidence and severity of leaf spot (Drechslera poae) on the Kentucky bluegrass varieties 'Merion' (resistant) and 'K109' (susceptible) was determined by sampling whole tillers and leaf clippings prior to each mowing. The 'K109' plots were split into treatments receiving nitrogen fertilizer and plots not receiving nitrogen. Severity was highly correlated with incidence for both varieties. The relationship remained high for the 'K109' plots whether or not nitrogen was applied. Regression coefficients of determination for the experiments ranged from 86.1 to 94.5 %. Either whole tillers or leaf clippings could be used to predict disease severity of the leaf spot phase of D. poae based upon incidence data. These results suggest that incidence data could be used to evaluate disease control strategies such as the use of improved bluegrass for resistance to D. poae or the use of fungicides." |
