摘要
田间测定了烟嘧磺隆对玉米田杂草的防除效果，结果表明，在玉米出苗后、杂草3～5叶期，每公顷用4％烟嘧磺隆悬浮剂1800ml茎叶喷施，对玉米田一年生杂草反枝苋、藜、狗尾草、稗草、马唐有较好的防除效果，总株防效为85．6％，总鲜重防效为96．8％。
Weed control effect was tested with 4 % nicosulfuron SC in field. The result showed that the annual weeds, such as Amaranthus retroflexus L, Chenopodium album L, Setaria viridis （L） Beauv, Echinochloa crus-galli （L） Beauv, Digitaria sanguinalis （L） Scop, could be effectively controlled by spraying nicosulfuron at the dosage of 1 800ml/hm^2 , in maize 4- 6 leaf stage and weeds at 3 - 5 leaf stage. After 45 days, the control effect was 85.6 % and the control effect of weed fresh weight was 96.8%.
