| [Aims] Preparation and characterization of 40% Bifenazate.Etoxzaole suspension concentrate to reduce single dosage and cost of production preventing and controlling the citrus red mite Panonychus citri, and extending their service life. [Methods] The wet milling was used to prepare the SC with different dispersants, thickeners and antifreezers in the formulation through the tests of particle size, viscosity, dispersion, pH, storage stability at low temperature and high temperature. [Results] The best formulation was bifenazate 25%, etoxzaole 15%, AEO 2%, D1002 2%, sodium lignosulfonate 6%, ethylene glycol 5%, xanthan gum 0.1%, deionized water up to 100%. [Conclusions] The mixture ratio of the suspension concentrate formula is reasonable, all the indicators met the relevant standards, the field control efficacy against the citrus red mite Panonychus citri was excellent. The guidance for the development and production of suspension concentration with bifenazate and etoxazole was provided. |
