설부병에 원인이되는 Typhula species 대하여 살균제의 감수성을 실내에서 연구하였다. 살균제, 노즐타입 및 살포약량에 대한 효과와 살균제의 살포시기(이른가을과 늦가을)에 대한효과 위스콘신에서 겨울동안 설부병에 대한 약제의 방제 효과에 대한 영향을 평가하였다. 모든 살균제는 Typhula spp.의 8균주에 대하여 실내 PDA 배지 상에서 균사생장을 효과적으로 억제하였다. 8균주에 대한 균사생장 저지효과는 propiconazole $1.0{mu}g$ (a.i) / ml에서 가장 효과적이었다. Typhula incarnata 2균주는 T. ishikariensis 6균주(3품종)보다 모든 살균제에서 더 감수성을 보였다. 2년 동안 포장시험에서 7개 농약을 2지역에서 살포하였으나, 무처리구에서만 병 발생이 심각하였다. Propiconazole이 설부병 방제에 2년 동안 2곳에서 가장 효과적이었다. 약제 살포용 노즐타입이나 살포약량은 두 곳 시험에서 모두 통계적으로 유의성이 없었다. 살제 살포시기도 설부병 방제에 통계적으로 유의성이 없었다.
Commercial formulation of fungicides was studied in vitro for sensitivity against Typhula species causal agents of Typhula blight. Efficacies of fungicides application, spray volume, nozzle types and fungicides applied time (early fall and late fall) were evaluated for their influence on the chemical control of Typhula blight of turfgrass during the winter season in Wisconsin. All fungicides effectively reduced the mycelial growth of eight isolates of Typhula spp. in vitro on potato dextrose agar (PDA) media. For inhibitory effects on mycelial growth of eight isolates, propiconazole was the most effective at $1.0{mu}g$ active ingredient (a.i) / ml of PDA. Typhula incarnata two isolates were significantly more sensitive to all fungicides of PDA than six isolates of three varieties of T. ishikariensis. For 2 years in field experiment, unsprayed control has significantly more disease severity than seven fungicides were applied to field plots at two locations. Propiconazole was the most effective for controlling Typhula blight, at two locations in both years. The level of disease control was not dependent on fungicides spray volume or nozzle types at two locations. The disease damage treated with triadimefon applied time (early fall and late fall) was not significantly different at two location for two years.
