adjuvant solution
2.For solving the bad wetting of the pesticide solution and the suitable concentration of thepesticide adjuvant for spraying the DSTdynamic surface tension of several adjuvantsLAS,OP-10 and FT-248 and the dynamic contact anglesDCA of little drop on paraffin and maize weredetermined. The effect of DST and DCA on wettability of spraying droplet was discussed.
