本文针对豆威（ＣＬＡＳＳＩＣ）杀草谱，施用剂量，处理时期与其它除草剂混用及安全性问题进行了研究。结果表明：采用（１５－２０）ｇａｉ／ｈａ的剂量进行土壤处理及２０ｇａｉ／ｈａ剂量苗后茎叶处理即可达到该药剂理想防效，对禾本科株防效为７７％，阔叶草株防效达５０％，鲜重防效分别为８５％和７０％，其施用方法应视当年土壤墒情而定，土壤墒情良好可采用播后苗前土壤处理，反之建议采用苗后二片复时期茎叶处理。ＣＬＡＳＳＩＣ与拿捕净搭配应用在２０ｇａｉ／ｈａ＋２４０ｍｌａｉ／ｈａ剂量下防效显著增加。ＣＬＡＳＳＩＣ在正常用量下对大豆本身及后茬作物具有较好的安全性。
In this paper, we studied the application of CLASSIC to kill herbicides, application rate, mixing time and other herbicide treatment and safety issues. The results showed that the ideal control effect of the agent was achieved when the soil was treated with the dose of (15-20) gai / ha and the stems and leaves treated with the 20gai / ha seedling, the control effect on the gramineous plants was 77% The control effect is up to 50%, and the fresh-weight control efficiency is 85% and 70% respectively. The application method should depend on the soil moisture content of the year. Soil with good soil moisture can be treated with pre- Stem and leaf treatment. CLASSIC and catching the net with the application of 20gai / ha + 240lai / ha dose significantly increased. CLASSIC in the normal amount of soybean itself and after the crop has good safety.
