Abstract/Contents: | "In July, 1986, turf samples were received from two Kentucky golf courses, where superintendents reported inability to control Pythium blight with metalaxyl. A fungus typical of Pythijm aphanidermatum was isolated from all tillers cultured, and identification was confirmed based on oospore, sporangial, and antheridial morphology. Recovered isolates were able to grow on medium containing 100 ppm metalaxyl. Two representative isolates, plus a metalaxyl-sensitive isolate from Pennsylvania, were tested on pot-grown 'Penncross' bentgrass for pathogenicity and fungicide sensitivity. All isolates were pathogenic, producing symptoms typical of Pythium blight. The Kentucky isolates were not controlled by metalaxyl, but were controlled by propamocarb and fosetyl aluminum. The Pennsylvania isolate was controlled by all three fungicides." |
