| Abstract/Contents: | "In a greenhouse screening experiment, two-month-old creeping bentgrass was topdressed with fungus-infested sand-cornmeal. After six 12-h leaf wetness periods, 97-100% of plants topdressed with Sclerotinia homoeocarpa were killed. When potential antagonists (isolates of filamentous fungi) were applied immediately after S. homoeocarpa, disease was reduced by 10-90%. Sand-cornmeal topdressings were also applied to field plots on a bentgrass sward maintained similar to a golf-course putting green. Plots were inoculated with S. homoeocarpa on 5 August. Weekly applications of five antagonist-infested topdressings (0.4L/m2) were made from 5 June to 11 Sept. 1987. Maximum disease intensity in plots treated with potential antagonists ranged from 4-65%, compared to 85% in control plots. In a similar experiment using chopped antagonist-infested grain as a topdressing, six additional isolates of fungi limited disease intensity to 2-6%, compared to 31% in control plots. Autoclaved uninfested topdressings limited disease intensity to 65% and 9%, compared to 85% and 31% in control plots, respectively. Both general and specific mechanisms of antagonism seemed to be operating. Isolates ineffective in the field were also ineffective in greenhouse screening experiments, but not vice versa." |
