摘　　要：为探究低毒、低残留、高效的药剂防除紫茎泽兰的方法,选用50%特丁赛草隆、75%苄.草苷、41%草甘膦异丙胺盐、50%草甘膦等4种药剂,在紫茎泽兰生长期和非生长期实施叶片正反面喷施试验。结果表明,以41%草甘膦异丙胺盐水剂、50%草甘膦可湿性粉剂效果较好。41%草甘膦异丙胺盐水剂150 mL+水125 00 g(浓度为1.16%)株防效达100%,50%草甘膦按50 g+洗衣粉10 g+水12 500 g株防效达75.33%。同种药剂生长期较非生长期防除效果好,41%草甘膦异丙胺盐水剂在生长期浓度达1.16%时株防效达100%,而在非生长期浓度为1.6%时株防效仅达62.6%。In order to select high-efficiency,low-toxicity and low-residue chemicals for controlling Eupatorium adenophorum,4 herbicides were chosen which were sprayed on the leaves of weeds during both the growing and non-growing seasons.The results showed glyphosate 41% AS and glyphosate 50% WP had better control results than others.The efficiency of the treatment of glyphosate 41% AS 150 mL ＋ water 12 500 g（the concentration of 1.16%）was 100%,and that of glyphosate 50% WP＋detergent powder 50 g ＋ water 12 500 g was 75.33%.The effect of the same herbicide in growing season is better than that in non-growing senson.The treatment of glyphosate 41% AS at the concentration of 1.16% in growing season had an efficiency of 100%,while only 62.6% in non-growing season.
