以Ｒ为溶剂，９５％乙醇为乳化剂、助溶剂和稀释剂，配成复方灭鼠剂８８－１不同浓度的乳油，经低温相溶性、自发乳化性和乳化稳定性测定，得到２０％和５％各两组配方。生物测定结果表明：８８－１加入Ｒ后药效没有影响，８８－１乳油热贮后毒力不减。现场试验得８８－１乳油相对于原粉适口性不降低，８８－１乳油现场灭鼠效果达８５％以上。 Using R as solvent and 95% ethanol as emulsifier, cosolvent and diluent, the compound rodenticides 88-1 emulsifiable concentrates were formulated into different concentrations of emulsifiable concentrates. The low temperature compatibility, spontaneous emulsification and emulsification stability were tested to obtain 20% and 5% each two groups formula. Bioassay results show that: 88-1 added to R after the drug has no effect, 88-1 EC storage of virulence after unobvious. Field trials 88-1 emulsifier relative to the original palatability does not reduce, 88-1 EC on-site rodent control effect of more than 85%.
