Efficiency and Safety of 50% Amidosulfuron WDG on Controlling Annual Broad Leafweed in Fields of Spring Wheat

50％酰嘧磺隆是防除春小麦（Triticum aestivum）田间阔叶杂草的新型除草剂,为明确其田间使用的除草效果及对春小麦的安全性,进行了田间药效试验.结果表明,50％酰嘧磺隆水分散粒剂在春小麦田间应用能有效防除多种一年生阔叶杂草,使用剂量以45～60 mL/hm2为宜,在春小麦3～5叶期、双子叶杂草2～8叶期每公顷对水300 kg茎叶喷雾.对供试春小麦高原483号品种安全,使用后增产3.32％～11.43％.

50％ Amidosulfuron WDG is a new herbicide for controlling weeds in fields of spring wheat.Field trial was conducted to clarify its effect on controlling weed and its safety for spring wheat.The results showed that 50％ Amidosulfuron WDG could effectively control several kinds of broadleaf weeds.Its normal dosage was 45～60 mL/hm2 in 3～5 leaf stage and broadleaf at 2～8 leaf stage with 300 kg spray of stems and leaves.The appliciation of 50％ Amidosulfuron WDG was safe to the spring wheat variety Gaoyuan No.483 and the yield of wheat was 3.32％～11.43％ more than that of CK.
