Effect of 10 Kinds of Auxiliaries on Herbicide Reduction and Synergism of Soybean Stems and Leaf Weeding

为了明确不同助剂对大豆茎叶除草剂的减量增效作用,选择10种助剂对除草剂15%精吡氟禾草灵乳油、5%精喹禾灵乳油、250 g/L氟磺胺草醚水剂进行大豆田苗后茎叶除草减量试验。结果表明,助剂施倍丰、激健、速捷、云展、益泽、华诺均使除草剂减量25%,而且助剂施倍丰、激健能显著增效达8%左右,哈速腾、天达、怀农特、展透4种助剂在除草剂减量25%的条件下,杂草防除效果不理想。

In order to clarify the effect of different auxiliaries on the herbicide reduction and synergism of soybean stem and leaf weeding,10 kinds of auxiliaries were selected for the experiment of reducing the amount of herbicide after soybean seedling with 15% Fluazifop-P EC,5% quizalofop-p-ethy EC and 250 g/L fomesafen AS.The results showed that auxiliaries such as Shibeifeng,Jijian,Sujie,Yunzhan,Yize and Huanuo all reduced the herbicide usage by 25%,synergistic effect of auxiliaries such as Shibeifeng and Jijian could reach about 8%,the weed control effect of four auxiliaries as Hasuteng,Tianda,Huainongte and Zhantou were unsatisfactory under reducing the herbicide usage by 25%.
