| Abstract/Contents: | "The disease suppression potential of 37 putative isolates of Typhula phacorrhiza was evaluated on a sward of creeping bentgrass cv. Penncross with a history of severe typhula blight (gray snow mold) induced by T. ishikariensis and T. incarnata. Isolates were applied as infested grain at 100 g/m2 on 29 Nov. 1986. Following 116 days of snow cover, suppression of typhula blight ranged from 0 to 88% for the isolates tested. Recovery of the turfgrass in treated areas occurred within 2.5 to 8 weeks after the initial disease rating on 30 March 1987. A simple correlation coefficient (r = 0.86) indicated that an inverse relationship exists between disease suppression and recovery-time for turfgrass. Isolates of T. phacorrhiza paired with T. ishikariensis or T. incarnata and incubated at 1°C for 4 weeks on potato/malt (BASM) agar or water agar showed no evidence of antibiosis or mycoparasitism as a mode of antagonism. Radial growth of the antagonistic isolates on BASM at 1°C was not correlated with disease suppression obtained in the field. The relationship of disease suppression with the colonization of the thatch layer of turfgrass by isolates of T. phacorrhiza was investigated as a factor involved in the suppression of typhula blight." |
