포커스 - 골프장 농약사용에 대한 오해와 진실 - 엄격한 규제장치 통해 잔디밭.유출수 중 농약잔류 없어 -
심규열,Sim, Gyu-Yeol 한국작물보호협회 2009 자연과 농업 Vol.251 No.-
골프장이 농약을 사용하여 환경오염을 일으킨다는 일부의 주장은 전혀 과학적인 자료와 사실적인 결과에 근거하지 않고 막연한 우려와 일부 자료들을 단순 비교하는데서 유발된 오해가 많다. 엄격한 사용규제를 안전장치가 이중삼중이어서 무분별한 사용을 할 수도 없다.
Sclerotinia homoeocarpa에 의한 잔디동전마름병(Dollar spot)의 약제 저항성균 발생 및 방제
심규열,민규영,신현동,이현주 한국잔디학회 2001 한국잔디학회지 Vol.15 No.1
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 32ppm($\mu\textrm{g}$/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 originate 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.
