Study on the Effects of Phoxim, Fenpropathrin and Its Mixture on Respiration of Soil Microbe.

采用密闭法，测定了辛硫磷、甲氰菊酯及其混剂对土壤微生物呼吸的影响，并对其进行了安全性评价。结果表明，辛硫磷和甲氰菊酯混合使用对土壤呼吸基本无影响。安全性评价认为甲氰菊酯、辛硫磷及其混剂对土壤微生物均属于低毒级或无实际危害级农药。

The effects of phoxim, fenpropathrin and its mixture on respiration of soil microbe were studied by closed or direct absorption method. And the environmental safety of these pesticides to the soil was evaluated, too.
