摘要： 为探讨豆杰添加不同助剂对大豆田阔叶杂草的防除效果及安全性，选用豆杰84WDG 22.5 g/hm2添加4种助剂Ecosurf SA-9、Triton X-100和Tergitol L-62、ULD-E于大豆出苗后喷施。结果表明：施药10天后目测各处理对大豆田鸭跖草、刺儿菜、苣买菜等的鲜重防效都达到了60%以上；但对藜、问荆无效，除ULD-E对大豆有触杀型药害，大豆叶部有黄裼色斑点外，其余3种助剂对大豆均安全。施药45天后各处理对各种杂草株防效均较差，对鸭跖草、刺儿菜的鲜重防效：豆杰+X-100分别达到89.7%、98.1%以上，豆杰+SA-9在95.9%、78.8%以上，豆杰+L-62在92.5%、97.2%以上，豆杰+ULD-E在91.5%、92.7%以上，各处理对苣荬菜的鲜重防效也较好，在85.2%以上，对苍耳、豨莶的防效均达到100%，各处理均好于豆杰单剂处理。从不同助剂的浓度看，以1000倍液对各杂草的防除效果最佳，其次是2000倍液，再次是500倍液。目测豆杰+助剂除草效果的依次为：Ecosurf SA-9> Triton X-100> Tergitol L-62 > ULD-E。

Abstract: FirstRate plus different auxiliaries were studied in soybean field to research their phytocidal effect of Commelina communis Linn, Cirsium setosum, Herba Sonchi Brachyoti and the other broadleaf weeds and safety. The results showed that the every phytocidal effect of all treats on individual weeds and fresh weight were more than 60% after ten days, but it were not effective to Chenopodium album and Epuisetum arvense. Ecosurf SA-9, Triton X-100 and Tergitol L-62 were safe to soybean, but ULD-E was unsafe because there were yellow spots on leafs. After forty-five days, the phytocidal effect of all treats on individual were all low control effect, but on fresh weight of Commelina communis Linn and Cirsium setosum were that FirstRate+X-100 was more than 89.7%, 98.1%, FirstRate+SA-9 was more than 95.9%, 78.8%, FirstRate+L-62 was more than 92.5%, 97.2%, FirstRate+ ULD-E was more than 91.5%, 92.7%. The phytocidal effects of all treats on fresh weight were more than 85.2% to Herba Sonchi Brachyoti and 100% to Siberia Cocklebur and Siegesbeckia. The every phytocidal effect of all treats was better than only FirstRate treat. The every phytocidal effect of different concentration of four auxiliaries were different, the 1000 time liquid was the best than the 2000 than the 500. The phytocidal effect of four auxiliaries were Ecosurf SA-9> Triton X-100> Tergitol L-62> ULD-E.
