【摘要】 筛选了五氟磺草胺和精噁唑禾草灵的最佳配比,研究了复配剂的油悬浮剂配方,并明确了该复配制剂的田间药效。结果表明,五氟磺草胺和精噁唑禾草灵的最适配比是2∶1;该油悬浮剂的最适配方是:五氟磺草胺的质量分数是4%,精噁唑禾草灵是2%,MOA-9P是15%,L-62是5%,有机膨润土是1%,气相法白炭黑是1%,油酸甲酯补足至100%;田间药效表明,6%五氟磺草胺·精噁唑禾草灵油悬浮剂18~36 g a.i./hm~2可有效防除直播稻田一年生杂草,并对水稻产量无影响。更多还原

【Abstract】 The best ratio of penoxsulam and fenoxaprop- p- ethyl,the concentrate of oil suspension and its field efficacy was evaluated. The best ratio of penoxsulam and fenoxaprop- P- ethyl was 2: 1; the suitable formulation composition was obtained as follows: 4% penoxsulam,2% fenoxaprop- p- ethyl,15% MOA- 9P,5% L- 62,1% organobentonite,white carbon 1% black,methyl oleate added up to 100%. At the field trial penoxsulam·fenoxaprop- p- ethyl 6% OD at 18 ~36 g a. i. / hm2 could control Poaceae weeds effectively in water direct- seeding rice.更多还原
