摘　　要：43%双氟磺草胺·2甲4氯异辛酯SC是防除春小麦田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,43%双氟磺草胺·2甲4氯异辛酯SC在春小麦田使用能有效防除多种一年生阔叶杂草,对供试春小麦高原483号品种安全,使用后增产8.09%以上。推荐使用剂量为1200~1500 mL/hm2,在春小麦3~5叶期、双子叶杂草2~8叶期兑水300 kg/hm2茎叶喷雾。Florasulam-MCPA-isooctyl 43%SC is a new herbicide for the control of broad-leaved weeds in the field of spring wheat.In order to determine its herbicidal effect on the field and safety of spring wheat,field efficacy test was conducted.The results showed that Florasulam-MCPA-isooctyl 43%SC could effectively control a variety of annual broad-leaved weeds when used in the field of spring wheat.The dosage was appropriate at 1200-1500 mL/hm2,and spray of 300 kg of stem and leaf per hectare was mixed with water at 3-5 leaf stage and 2-8 leaf stage of dicotyledon weeds in spring wheat.The safety of spring wheat plateau 483 was studied,and the yield was increased by 8.09%.
