摘　　要：84%氯酯磺草胺WG对大豆田鸭跖草防效的研究结果表明:84%氯酯磺草胺WG比对照药剂25%氟磺胺草醚AS施药量为375ga.i./hm2对鸭跖草的防效好,其施药量必须超过25.2ga.i./hm2;84%氯酯磺草胺WG对多年生苣荬菜、刺儿菜防效的研究结果表明:84%氯酯磺草胺WG比对照药剂48%苯达松AS施药量为1440ga.i./hm2对多年生苣荬菜、刺儿菜的防效好,其施药量必须达到37.8～50.4ga.i./hm2。The result of the control efficiency of cloransulam-methyl 84% WG to Commelina communis L. showed that the control efficiency of cloransulam-methyl 84% WG was better than that of fomesafen 25% AS applied in the dosage of 375 g a.i./ha. In order to control Commelina communis L., when cloransulam-methyl 84% WG was applied, it＇s dosage must be over 25.2 g a.i./ha. The result of the control efficiency of cloransulam-methyl 84% WG to Sonchus brachyoms DC. and Cephalanoplos segetum （Bunge） Kitam. showed that the control efficiency of cloransulam-methyl 84% WG was better than that of bentazon 48% AS applied in the dosage of 1440 g a.i./ha. When cloransulam-methyl 84% WG was applied to control Sonchus brachyotus DC. and Cephalanoplos segetum （Bunge） Kitam., it＇s dosage was 37.8-50.4 g a.i./ha.
