| Abstract/Contents: | "Antifungal activity of 20 chemicals registered to turfgrass diseases was evaluated. Among the chemicals, iprodione, benomyl, iprodione+thiram, pencycuron+tebuconazole, hexaconazole, and iprodione+thiophanate-methyl exhibited high antifungal activity to the dollar spot fungus. All isolates were greatly inhibited by the chemicals at the concentration over 32 ppm(μg/ml). However, sensitivity of the isolates to chemicals was varied at the lower concentration as 8 and 16 ppm as follows. The isolate originated from Ora golf course was resistant to iprodione and iprodione+thiophanate methyl, Gonjiam isolate to iprodion, Youngpyung isolate to iprodione+thiram, and Dogo isolate to iprodione+thiram, pencycuron+tebuconazole, and tebuconazole. It was found from this study that the varied chemical resistance among the isolates was positively related to the application time of the chemical in the golf course. Consequently, when a chemical was applied more often times than the others to the golf course, the fungal isolates originated from the field showed higher resistance to the former chemical. Effects of the chemicals on control of the dollar spot was evaluated in the field. All tested chemicals revealed over 70% disease control efficacy, however, mepronil+propiconazole was the best showing 83% control efficacy and followed by fenarimo, iprodione, terbuconazole, thiram, and thiophanate-methyl." |
