Preparation and Characterization of Spirodiclofen·Abamectin 24％ SC
[Aims] The formula of spirodiclofen·abamectin 24％ SC was prepared,and the performance was investigated.[Methods] The optimal mixing-ratio was determined by the co-toxicity coefficient method.The best formula was determined by single-factor test and orthogonal experiment.[Results] The optimal mixing-ratio of spirodiclofen and abamectin was 23∶1.The best formula was spirodiclofen TC 23.2％,abamectin TC 1.1％,D305 7％,magnesium aluminium silicate 0.8％,glycerin 6％,defoaming agent of CF580 0.3％,and distilled water making up to 100％.The optimal process was the volume of zirconium bead (d=1.2 mm) was 17 mL for 10 g of formulation,and the milling time was 2.5 h.[Conclusions] All specifications of the formulation meet the national standards for suspension concentrate.
