[0019] 30% emamectin benzoate · indoxacarb oil suspension concentrate, the composition (weight percentage, the same below) is: emamectin benzoate 10%, indoxacarb 20%, oil 3% acid, 4% oleic acid polyoxyethylene ether, 8% alkylphenol polyoxyethylene ether, 1% organic bentonite, 0.1% triethanolamine, and 100% methyl oleate.
[0020] Emamectin benzoate, indoxacarb, additives, solvents (except pH regulator and a small amount of solvent) were pre-mixed in a high-shear machine according to the formula ratio for 20 minutes, dispersed and pulverized by a high-pressure homogenizer to achieve particle size Diameter D95≤5um, add pH adjuster and remaining solvent into the brewing kettle, mix evenly, filter to obtain a uniform suspension, measure, pass the test (particle size D95≤5um), and pack. Preparation of 30% emamectin benzoate · indoxacarb oil suspension
[0026] Prepare 48% emamectin benzoate indoxacarb oil suspension by the method of embodiment 1

Abstract
The invention discloses a methylamino abamectin benzoate/indoxacarb oil suspension and a preparation method of the oil suspension. The oil suspension comprises the following components in percentage by weight: 0.5-10% of methylamino abamectin benzoate, 3-40% of indoxacarb, 2-25% of emulsifier, 0.1-10% of thickening agent, 0-5% of pH (potential of hydrogen) regulator, and the balance of solvent, wherein the total volume is 100%. The oil suspension disclosed by the invention is stable in physical and chemical properties and is not easy to decompose and deteriorate; by adopting the oil suspension, the adsorbing and seeping functions of a medicine to a target are increased, the effective utilization rate of the medicine is improved, the preventing and treating effects to injurious insects can be greatly improved; and the rice leaf folder prevention and treatment experiment shows that the preventing and treating effects can reach greater than 90% 7 days after the oil suspension is used, and the preventing and treating effects are far excellent than that of the existing methylamino abamectin benzoate/indoxacarb preparation; the oil suspension is stable in physical and chemical properties and is not easy to decompose and deteriorate; the adsorbing and seeping functions of a medicine to a target are increased; and the effective utilization rate of the medicine is improved.
Description
technical field [0001] The invention belongs to the technical field of pesticides, and relates to an emamectin benzoate indoxacarb oil suspension and a preparation method thereof. Background technique [0002] With the increasing pressure on my country's environment caused by pesticide production, the state has strengthened the management of pollutant discharge in the process of pesticide production. The State Environmental Protection Administration has compiled the "Pesticide Pollutant Discharge Standards", which clearly stipulates the discharge of 10 accumulated pollutants from pesticide enterprises. The National Development and Reform Commission also clearly pointed out that in order to reduce environmental pollution and protect the ecological environment, it is the development trend of current pesticide formulations to gradually replace the existing traditional formulations with environmentally friendly new formulations, especially water-based formulations.
