초록

A total of 24 isolates of S. homoeocarpa were isolated from 16 golf courses in Korea. Chemical resistance of 24 isolates was determined by in vitro fungal growth on fungicide-amended media with thiophanatemethyl (Benzimidazole fungicide family), tebuconazole (demethylation inhibitor fungicide family: DMI), and iprodione (dicarboximide fungicide family). Results indicated that 83.3% of 24 isolates were resistant to iprodione,62.5% resistant to thiophanate-methyl and 0% resistant to tebuconazale. The dual resistance of iprodione and thiophanate-methyl was 58.3.%. Occurrence rate of fungicide resistance of thiophanate-methyl and iprodione had no relation to turfgrass varieties and isolated locations of pathogen. In the filed test, procymidone, boscalid, and fluquinconazole+pyrimethanil effectively controlled the dollar spot of creeping bentgrass.
