进行了51%烟嘧磺隆·莠去津WP防除玉米田杂草的试验研究。结果表明:51%烟嘧磺隆·莠去津WP能有效防除玉米田马唐等禾本科杂草及马齿苋、铁苋菜等阔叶杂草。有效成分用量765 g/hm~2药后45 d,对马唐的鲜重防效达97.14%;对马齿苋的鲜重防效为97.60%;对铁苋菜鲜重防效为95.83%;对全草的鲜重防效为96.95%。51%烟嘧磺隆·莠去津WP是目前防除玉米田杂草的理想除草剂,其有效成分用量1530 g/hm~2对玉米安全。
A 51% nicosulfuron Atrazine WP was used to control weeds in corn field. The results showed that 51% Nicosulfuron and Atrazine WP could effectively control broadleaf weeds such as Crabgrass weeds and maize purslands such as purslane and iron amaranth in corn field. The fresh weight control of Crabgrass was 97.14% at the dosage of 765 g / hm ~ 2 for 45 d, 97.60% for fresh weight of purslane, and 95.83% Fresh grass weight control efficiency of 96.95%. 51% Nicosulfuron / Atrazine WP is the ideal herbicide for controlling weeds in corn field.
