| Abstract/Contents: | "Selected Pythium spp. isolated from bermudagrass (Cynodon dactylon ^D#^DOE C. transvaalensis) were tested for pathogenicity on Poa trivialis and Lolium perenne, two cool-season turfgrass species commonly used to overseed bermudagrass golf course greens during late fall in Florida. A grass blade infested with Pythium spp. was placed in each well (12-well tissue culture plates) in greens mix (85% sand, 15% peat), then the wells were seeded with one of the turfgrass species. After 7 days, each well was rated for disease severity, and Pythium spp. were reisolated from symptomatic tissue. An isolate of P. aphanidermatum was included in each test as a positive control; this isolate was highly pathogenic on both turf species, consistently causing above 80% disease severity in tests at 27°C. Three of four isolates of P. irregulare were moderately to highly pathogenic (46-80% disease severity) on Poa trivialis, but not on L. perenne. Isolates of P. graminicola and P. ultimum var. ultimum were not pathogenic on either cool-season turfgrass species. Pythium irregulare, although not reported as a Pythium blight pathogen in Florida, commonly inhabits bermudagrass and may become pathogenic on P. trivialis under favorable environmental conditions." |
