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1 200~1 500 m L/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。

摘  要:
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 1 200-1 500 m L/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%.
