Agent of pesticide emulsion solubilization by surface activity, can effectively improve the efficiency of the use of pesticides. This topic mainly by influencing the volume ratio of emulsion solubilization effect of surfactant components of the pesticide to identify the most suitable emulsifier. The experimental findings, the emulsification effect twelve calcium alkylbenzene sulfonate and styrylphenol polyoxyethylene ether of emulsifier and hydrophilic lipophilic balance number (HLB value) has a direct relationship, when emulsifier HLB value and the corresponding HLB value of pesticide required when fit, the best emulsifying effect. In addition, environmental temperature, emulsifier molecule structure will also affect the emulsifying effect. The results in the paper to improve the performance, reduce the solubilization emulsification pesticide environmental damage has an important reference.
