摘　　要：为了研究17%炔草酯·氟唑磺隆对冬小麦田间防除杂草效果及对作物生长发育的影响,进行了田间药效试验。结果表明,用17%炔草酯·氟唑磺隆可分散油悬浮乳剂1.33~4.00mL/hm^2对冬小麦田间杂草播娘蒿(十字花科阔叶杂草)、雀麦和野燕麦(禾本科杂草)进行处理,株防效和鲜质量防效均好于对照药剂(70%氟唑磺隆水分散粒剂和15%炔草酯可湿性粉剂),防效达90%以上,且有一定的增产效果,对冬小麦安全,无药害症状。考虑经济有效易降解,推荐使用剂量为1.33~2.67mL/hm^2(商品量)或51~102g/hm^2(有效成分)。Field experiments were conducted to study the effect of 17% Clodinafop·Fluearbazone OD on weeds in winter wheat field and its influence on crop growth. The results showed that the field weeds of winter wheat, Descurainia sophia(L.)Schur(Cruciferae broad-leaved weeds), Bromus japonicus Thunb. and Avena fatua L.(Gramineae weeds)were treated with 17% Clodinafop·Fluearbazone OD of the effective constituent dose 1.33-4.00 mL/hm^2, the preventing effect reached above 90% for each plant and the fresh quality of weeds, which were better than the two single dose of contrast agent(70% Fluearbazone WDG and 15% Clodinafop WP), the control effect was excellent and the wheat yield increased, it was safe and no drug damage symptoms for winter wheat. From the perspective of economic efficiency and easy degradation, the recommended effective constituent dose is 1.33-2.67 mL/hm^2(commercial volume) or 51-102 g/hm^2(active ingredient).
