【摘要】 将甲氰菊酯和单甲脒通过复配对桔全爪螨进行室内毒力测定,表明两种药剂的各种配比均对桔全爪螨存在着不同程度的增效作用,其中以甲氰菊酯与单甲脒按1:4的比例复配增效作用最为明显,共毒系数达到373。田间药效试验也表明,20％的混剂乳油(4％甲氰菊酯+16％单甲脒)的药效明显高于20％的甲氰菊酯乳油和25％的单甲脒乳油。更多还原

【Abstract】 The results of toxicity testing on Panonychus citri Mcgregor with Fenpropathrin and Chlordimeform and their mixtures showed that all mixtures had some synergism. The mixed proportion of Fenpropathrin and Chlordimeform with 1:4 had the most obvious synergism, co-toxicity coefficient of them were. The pesticide testing on field showed that effect of 20% mix ture EC (4% Fenpropathrin +16% Chlordimeform) was better than that of 20% Fenpropathrin EC and 25% chlordime from EC.更多还原
