팔 녹두에 적합(適合)한 제초제선발(除草劑選拔)을 위하여 1980~1983 년(年)의 4 개년(個年)에 걸쳐 작물시험장(作物試驗場)에서 포장시험(圃場試驗)과 pot 시험(試驗)한 결과(結果)를 요약(要約)하면 다음과 같다. 1. 제초제(除草劑)에 대한 내성(耐性)은 콩이 가장 컸으며, 녹두, 팥의 순서(順序)이다. 2. 출아전처리제(出芽前處理劑)로서 alachlor와 그외 7 종(種)의 제초제(除草劑)에 대한 약해(藥害)를 검정(檢定)한 결과(結果) 약해(藥害)를 비교적(比較的) 덜 일으키는 제초제(除草劑)는 팥에서 chloramben, linuron, metribuzin 등(等)이며, 녹두에 서 alachlor. butachlor 등(等)이었다. 3. 출아후처리제(出芽後處理劑)로서 팔, 녹두에 외관상(外觀上) 약해(藥害)를 일으키지 않는 제초제(除草劑)는 alloxydim, Dowco 453, fluazifop 등(等)이었다. 4. 출아전처리제(出芽前處理劑)로서 terbutryn 150g, a.i./l0a 처리(處理)가 팔과 녹두에 대한 잡초방제효과(雜草防除効果)가 가장 양호(良好) 하였으나 약해(藥害)의 우려가 있으며, 출아후처리제(出芽後處理劑)로서 acifluorfen 30g. a.i./10a 처리시(處理時) 잡초방제효과(雜草防除効果)가 가장 양호(良好)하였고 약해(藥害)도 20일(日) 이내(以內)에 회복(回復)되어 수량(收量)에는 영향(影響)을 미치지 않았다. 5 제초제(除草劑) 단일처리(單一處理) 보다는 혼합(混合) 및 조합처리시(組合處理時) 잡초방제효과(雜草防除効果)가 뚜렷하였으며 성분량(成分量)으로 10a당(當) 팥에서 linuron 50 g과 Dowco 453 l8g 또는 fluazifop 26g 조합처리(組合處理)가, 녹두에서 alachlor 131 g과 acifluorfen l5g 조합처리(組合處理)가 체초방제효과(體草防除效果)와 수량(收量)이 높았다.

To select appropriate herbicides for adzukibean and mungbean, a series of experiments was carried out in both field and pot from 1980 to 1983. Tolerance to the herbicides tested was highest in soybeans and followed by mungbean and adzukibean in the order. Pre-emergence herbicides showed relatively low phytotoxicity were chlorambem, linuron, and metribuzin for adzukibean and alachlor and butachlor for mungbean. Post-emergence herbicides showed no external phytotoxicity for adzukibean and mungbean were alloxydim, Dowco 453, fluazifop, etc.. For mungbean, terbutryn (1.5 kg, a.i./ha) which is pre-emergence herbicide showed the best weeding control efficacy but some possible phytotoxicity. Among post-emergence herbicides, acifluorfen (300 g, a.i./ha) showed the best weeding efficacy with no yield reduction though some phytotoxicity which recovered within 20 days. Compared to single herbicide application, the mixture or systemic treatments of herbicides showed much higher weeding control efficacy and seed yields: the systemic treatments of linuron (500 g, a.i./ha) / Dowco 453 (180 g, a.i./ha) or linuron (500 g, a.i./ha) / fluazufop (260 g, a.i./ha) for adzukibean and the mixture treatment of alachlor (1.31 kg, a.i./ha) / acifluorfen (150 g, a.i./ha) for mungbean, respectively.
