Method for producing environment-friendly insecticide

Abstract

The invention discloses a method for producing environment-friendly insecticide. The method comprises the process steps of 1, blending, wherein 25% by weight of abamectin, 8% by weight of sodium tripolyphosphate, 20% by weight of carboxymethylcellulose, 8% by weight of high-gold thiazone, 2% by weight of sodium silicate and the balance water are selected; 2, dissolving, wherein the raw materials are put in a reaction still, xanthan gum and sodium acrylate are added, and stirring is carried out till the raw materials are completely dissolved; 3, modifying, wherein alkyl sodium sulfonate is added into the step 2, the temperature is controlled to range from 75 DEG C to 85 DEG C, and stirring is carried out for 2 h; 4, insecticide property enhancement, wherein spinosad is added into the mixed liquid obtained in the step 4, and the addition of spinosad accounts for 2% of the mixed liquid; 5, stabilizing, wherein the mixed liquid is added into the reaction still, and the photosynthesis and normal growth of crop leaves are not influenced. The insecticide can be processed into a liquid agent, the insecticide is directly sprayed without being diluted when used, the insecticide can also be put in a spraying tank to be prepared into spray, and household use is convenient.

Description

technical field [0001] The manufacturing process of chemical pesticides involved in the present invention, in particular, relates to a production method of an environmentally friendly insecticide. Background technique [0002] At present, pesticides have been widely used in the field of agricultural production. With the development of agriculture, especially the emergence of large-scale contracted farmland, the demand for pesticides is increasing day by day. Yet along with the widespread use of pesticides, environmental problems are becoming more and more serious. The chemical components contained in the pesticides have changed the soil structure and polluted the water source. The application number is that CN94101332.4 discloses a pesticide and its production process. Insecticide, characterized in that it contains 2-dimethylamino-1,3-dithiosulfonate ammonium propane, prepared by reacting 3-dimethylamino-1,2-dichloropropane and ammonium thiosulfate obtained, and its feedin...

Yet along with the widespread use of pesticides, environmental problems are becoming more and more serious. The chemical components contained in the pesticides have changed the soil structure and polluted the water source. The application number is that CN94101332.4 discloses a pesticide and its production process. Insecticide, characterized in that it contains 2-dimethylamino-1,3-dithiosulfonate ammonium propane, prepared by reacting 3-dimethylamino-1,2-dichloropropane and ammonium thiosulfate obtained, and its feeding ratio is 1:2.03-2.05, heated to 73-76°C under stirring, kept warm for 2-4 hours, then continued to heat up to 80-85°C, kept warm for 0.5-1.5 hours, cooled and adjusted the pH to slightly It is acidic and collects the reaction products. This insecticide has a significant effect on pest control, low dosage, does not affect the soil properties when used, and has better storage stability than similar products at present. The time is short, the drug effect is low, and it is unstable, not environmentally friendly, and the degree of environmental pollution is large, and it cannot supplement nutrients to plants.
