Abstract
The invention discloses a self micro-emulsified phentriazophos emulsifiable concentrate, comprising 10 percent- 40 percent of phentriazophos, 1 percent-30 percent of surface active agent, 1 percent-10 percent of stabilizer and the other solvents. The percents relate to weight percent. Firstly, the phentriazophos is dissolved in the solvents to get the mixed solution of the phentriazophos by evenly dispersion. Then, the surface active agent is added in the mixed solution of the phentriazophos to get even mixed solution by evenly dispersion. Lastly, the stabilizer is added in the even mixed solution to stir up evenly, with the result that red-brown phentriazophos emulsifiable concentrate is made. Based on nonuse of aromatic organic solvent and reduction of the dosage of the other organic solvents, the invention of the phentriazophos emulsifiable concentrate can fully play the efficacy of the phentriazophos, can enhance insecticidal efficacy and can effectively reduce the pollution to environment.
