【摘要】 为了明确磺酰脲类麦田除草剂氟唑磺隆与苯磺隆混配的联合作用关系,采用温室盆栽法进行活性测定,等效线法评价二者的最佳配比。研究结果表明,两种药剂混用对敏感杂草猪殃殃(Galiumaparin)具有增效作用,在苯磺隆和氟唑磺隆(15,23.50)到(25.97,15)两等效线坐标点之间范围增效作用最明显,此两点相互作用指数为3.3924和2.9083。可见,氟唑磺隆15～23.50ga.i./hm2与苯磺隆15～25.97ga.i./hm2的剂量范围配比为二者的最佳配比。更多还原

【Abstract】 The interaction of flucarbazone and tribenuron was evaluated and the best ratio of the two herbicide was determined by Isoboles. The tested result showed that flucarbazone mixed with tribenuron significant synergism on Galium aparine. And the most obvious synergism is between the scope of (15 to 23.50 g a.i./ha) and (15 to 25.97 g a.i./ha), this index of interaction reached 3.392 4 and 2.908 3.更多还原
