摘　　要：为明确高效氟吡甲禾灵、三氟羧草醚的联合作用类型及和25%高氟吡·三氟羧草醚乳油对花生田杂草的防除效果以及对花生的安全性,采用茎叶喷雾法测定了2种除草剂室内联合作用类型,并对筛选的25%高氟吡·三氟羧草醚乳油进行了田间防效验证。结果表明,高效氟吡甲禾灵、三氟羧草醚以1∶4复配对防除花生田一年生禾本科杂草有增效作用,25%高氟吡·三氟羧草醚乳油的推荐使用剂量为150.0~187.5 g a.i./hm^(2),药后46 d对杂草的总鲜质量防效可达到92.82%~95.72%。高效氟吡甲禾灵、三氟羧草醚复配对防除狗尾草等杂草增效作用明显,25%高氟吡·三氟羧草醚乳油能够有效防除花生田一年生杂草,并对花生安全。The study aims to clarify the combination effect of haloxyfop-P-methy with acifluorfen,and the control efficiency and security of haloxyfop-P-methy·acifluorfen 25%EC against weeds in peanut field.The method of stem-leaves spraying was used to determine the combination effect type of two herbicides indoor,and field trail was carried out to certificate the control efficiency of haloxyfop-P-methy·acifluorfen 25%EC in peanut field.The results showed,Haloxyfop-P-methyl and acifluorfen mixed at the ratio of 1∶4 had synergistic effect to annual gramineous weeds in peanut field.The recommended dosage of 25%haloxyfop-P-methyl·acifluorfen EC was 150.0-187.5 g a.i/ha,the control efficacy to overall fresh mass of weeds could reach 92.82%-95.72%after 46 days.It has obvious synergistic effect to Setaria viridis etc weeds when haloxyfop-P-methyl was mixed with acifluorfen.25%haloxyfop-P-methyl·acifluorfen EC can effectively control annual weeds in peanut field and it is safe for peanut.
