| Abstract: | Through the orthogonal optimization,the optimal formula of 2.5% spinosad SC was obtained as 2.5%spinosad,1.83%D-425,6.17%WP-003,4.5%ethanediol,1.5%Veegum,0.2%defoamer 630 and distilled water.The optimized technology showed that vertical sand mill could be used to produce spi-nosad SC,the optimized volume of zirconium bead was 2 times of the preparation,and the optimized milling time was 1.5 hours.Under the conditions of pH value as 6.8~7.0,after storing at （54 ＆#177;2）℃for 14 days, the suspension percentage of the spinosad SC was over 85%with no precipitation and stratification,and it had good pourability and other indicators. |
