Abstract
The experiment was crried out to evaluated the herbicidal properties of bensulfuron methyl [methyl 2-[[[[[(4, 6-dimethoxy pyrimidine-2yl) amino] carbonyl] amino] sulfonyl] methyl] benzoate]. No phytotoxicity was observed when bensulfuron methyl was applied at 3 and 6 g a.i./ 10a while the application rate 12 g a.i./10a slightly retared the growth of rice. The phytotoxicity decreased as the application time was delayed. The effect of application rate, leaching grade, transplanting depth, soil type and temperature on crop injury was little. Japonica variety (Dong-Jin) was more sensitive to bensulfuron methyl than indica X japonica variety (Sam-Kang). Bensulfuron methyl controlled effectively perennial weeds such as Sagittaria pygmaea Miq., Potamogeton diatinctus A. Benn., Cyperus serotinus Rottb., Sagittaria trifolia L., Eleocharis kuroguwai Ohwi. including most annual weeds except Echinochloa crus galli P. Beauv. The effect slightly decreased with lowering the temperature increasing the leaching grade. Application time and soil type employed did not affect the weeding effect.
신규(新規) 제초제(除草劑) bensulfuron methyl(DPX-F5384)의 약해(藥害) 및 제초효과(除草效果) 변동요인(變動要因)을 구명(究明)하여 다음과 같은 결과(結果)를 얻었다. 1) 이앙묘(移秧苗)(3.5 엽묘(葉苗), 삼강(三綱)벼)에 대하여 bensulfuron methyl 3~6g a.i./10a의 처리약량수준(處理藥量水準)에서는 대체로 안전(安全)하고 그 이상(以上)으로 약량(藥量)이 증가(增加)되면서 약해(藥害)는 약간식(若干式) 증대(增大)되었으나, 12g q.i./10a 처리(處理)에서도 그 약해(藥害)는 경미(輕微)하였다. 처리시기(處理時期), 누수량(漏水量), 온도(溫度), 이앙심도(移秧深度), 토양특성(土壤特性)의 차이(差異)에 따른 약해변동(藥害變動)은 거의 없었다. 품종간(品種間)에는 인도형(印度型)
