摘要
40%烟嘧磺隆.2,4滴异辛酯油悬浮剂是烟嘧磺隆、2,4滴异辛酯复配的玉米除草剂,本文对其杂草防除效果和玉米安全性进行了研究。结果表明,在玉米3～5叶期喷雾,剂量为600～720 ga.i/hm2(有效成分)时,药后45 d对杂草防效达到86.2%～99.2%,当剂量与40%2,4滴丁酯.烟嘧磺隆相同时,防效相当,安全性较好,与人工除草相比,产量差异不大。
40% Nicosulfurono2,4-D isooctyl ester is a new herbicide applied to corn field. Its controlling effect of weeds in corn field and its safety was studied in the experiment. The results showed that application of 40% Nicosulfurono2,4-D isooctyl ester at 600 - 720g.ai/ha at 3 - 6 leaf stage, its control effects of annual weeds 45 days after spraying was 86.2 - 99.2%.
