Abstract

The experiment was carried out to evaluated the interaction between perfluidone(2-methyl-4-phenylsulphonyltrifluoromethylsulphoanilide) and bifenox(2,4-dichlorophenyl-3-methoxycarbonyl-4-nitrophenylether). A synergistic effect was found between perfluidone and bifenox. The highest synergistic effect on Echinochloa crus-galli (L.). Beauv. was obtained when 10 g a.i./10a of perfluidone was combined with 24.9 g a.i./10a of bifenox. However, bifenox should be increased to 33.3, g a.i./10a to obtain the highest synergistic effect when applied to Cyperus serotinus Rottb. at 1.0-1.5 leaf stage. Sagittaria pygmaea Miq. at 0.5-1.0sleaf stage was completely controlled by the lowest combination rate employed.

일년생잡초(一年生雜草) 피와 다년생잡초(多年生雜草) 너도방동산이 및 올미에 대한 perfluidone과 bifenox의 혼합처리(混合處理)에 의한 상호작용(相互作用)을 colby법(法) 또는 등효과선법(等效果線法)(Isobole)에 의(依)하여 평가(評價)하였다. 1. 피(1.0~1.5엽(葉))에 대(對)한 두 제초제(除草劑)의 상호작용(相互作用)은 상승효과(相乘效果)를 나타내었으며 상호작용지수(相互作用指數) 1의 최대(最大) 치(値)는 perfluidone과 bifenox의 조합비(組合費) 10:24.9ga.i./10a 일 때로 나타났다. 2. 너도방동산이(1.0~1.5 엽(葉))에 대해서도 두 제초제(除草劑)의 혼합처리시(混合處理時)에 상승효과(相乘效果)를 나타냈으며, perfluidone과 bifenox의 혼합비(混合比)가 10:33.3 ga.i./10a 일 때 상호작용지수(相互作用指數) I의 최대치(最大値)를 나타냈다. 3. 올미(0.5~1.0 엽(葉))에 대해서는 각(各) 단제처리시(單劑處理詩)의 효과(效果)가 매우 우수하였던 관계로 혼합처리시(混合處理時)의 그 상호작용(相互作用)은 검정(檢定)키 어려웠다.
