In order to effectively prevent and control the thrips on green beans,the formulation of cyantraniliprole·chlorfenapyr 25％SC was developed.Using wet grinding process,the single factor method was used to screen out suitable adjuvants such as wetting and dispersing agents,thickeners,antifreeze agents,defoamers and their dosages,and the optimal formula of cyantraniliprole·chlorfenapyr 25％SC product was determined,namely 5％cyantraniliprole(100％off),20％chlorfenapyr(100％off),3％DS707,2％DS505,4％ethylene glycol,0.2％kathon,0.5％defoamer 630,0.2％xanthan gum,1.2％magnesium aluminum silicate,and make up with deionized water.The results showed that the suspension rate of the product was greater than 90％,and the decomposition rate was less than 5％after 14 days of hot storage.All technical indicators met the requirements of SC.Field efficacy trials showed that the product had a high control effect on bean thrips,and the control effect reached more than 94％10 days after application.
