摘要
三唑磷和水胺硫磷以及它们的复配制剂对桔全爪螨进行室内毒力测定，表明三唑磷的毒力明显大于水胺硫磷，两种药剂的各种复配均对桔全爪螨存在着不同程度的增效作用，其中以三唑磷和水胺硫磷按１：４的比例复配增效作用最为明显，共毒系数达到２５８。田间药效试验也表明，３０％ 的混剂乳油（６％ 三唑磷＋ ２４％ 水胺硫磷）１０００倍液的药效明显高于４０％ 的水胺硫磷１０００倍液乳油，而与２０％ 的三唑磷乳油１０００倍液相当。
The results of toxicity test to Panonychus citri McGregor with triazophos and isocarbophos each and their mixtures showed that the toxicity of triazophos was bigger than that of isocarbophos, and all mixtures had some synergism.The mixed proportion of triazophos and isocarbophos whth1:4 had the most obvious synergism, and their co-toxicity coefficient were 258.The control effects showed that effect of 30% mixture EC(6% triazophos+24% isocarbophos) 1000x was better than that of 30% isocarbophos EC 1000x,equal to 20% triazophos EC.1000x.
