Problems solved by technology

[0005] Chlorantraniliprole and rotenone products used in the existing pesticide market have shortcomings. Rotenone is mainly emulsifiable concentrate, and the dosage form of chlorantraniliprole insecticide products is mainly suspension concentrate, and xylene is often used in emulsifiable concentrate preparations. Toxic organic solvents, the shortcomings of the existing product formulations are relatively single; at present, the compound water dispersible granules of chlorantraniliprole and rotenone have not been reported

[0028] Embodiment 2: take by weighing chlorantraniliprole 0.1kg and rotenone 15.0kg, then with calcium lignosulfonate 15.0kg, alkylnaphthalene sulfonate 5.0kg, bentonite 22.0kg, sodium polyacrylate 0.2kg, sodium bisulfate 0.1kg, 20.0kg of diatomaceous earth and 22.6kg of calcium carbonate, after mixing evenly, pulverize into mother powder by ultra-fine jet mill, add 3.5kg of deionized water to the mother powder, mix evenly, granulate, dry, and sieve After sampling, analysis and qualified packaging, the compound water-dispersible granules of chlorantraniliprole and rotenone are made. After testing, the water content is less than 2%, the long-lasting foaming property (1min) is less than 7ml, and the wettability is less than 40s, and the accelerated heat storage stability is qualified. The preparation was diluted with water to carry out the field drug efficacy test, and its 1500 times solution had 90.2% and 92.3% control effects on cabbage aphids on the 7th day and 14th day after...

Embodiment 3

[0029] Embodiment 3: take by weighing chlorantraniliprole 60.0kg and rotenone 15.0kg, then with acrylic acid homopolymer sodium salt 5.0kg, benzyl naphthalene sulfonate 4.5kg, polyethylene glycol 5.0kg, dextrin 0.2kg, Sodium wood alcohol 0.3kg and bentonite 10.0kg, mixed evenly, pulverized into mother powder by ultra-fine jet mill, then added 6.8kg of deionized water to the mother powder, mixed evenly, granulated, dried, sieved and passed sampling analysis Packing, that is, making chlorantraniliprole and rotenone compound water-dispersible granules. After testing, the water content is less than 2%, the long-lasting foaming property (1min) is less than 7ml, and the wettability is less than 40s, and the accelerated heat storage stability is qualified. The preparation was diluted with water to carry out the field drug efficacy test, and its 3000-fold solution had 91.5% and 92.8% control effects on cabbage aphids on the 7th day and 14 days after the application, and the control ef...

Abstract

The invention discloses a chlorantraniliprole and rotenone complex insecticidal water dispersible granule and a preparation method thereof. The water dispersible granule comprises the following raw materials by weight: 0.1-60% of chlorantraniliprole, 5-15% of rotenone, 3-25% of dispersing agents, 3-5% of wetting agents, 1-25% of disintegrating agents, 0.1-0.5% of binders, 0.1-0.5% of stabilizing agents, 10-60% of carriers and 1-8% of deionized water. The preparation method is characterized by carrying out weighing according to the proportion, mixing the weighed materials uniformly and adding active ingredients, auxiliaries and the carriers; and carrying out ultrafine grinding on the formula materials and then pelletizing the powder by extrusion. The water dispersible granule overcomes theharm of emulsifiable concentrates to the environment, has good wettability, high disintegration speed, good dispersibility, high suspensibility and good heat storage stability, is easy to use and harmless to people, livestock and the environment, has simple preparation process and is suitable for industrial production and large-area popularization.

Description

technical field [0001] The invention relates to a pesticide preparation, in particular to a compound insecticidal water-dispersible granule of chlorantraniliprole and rotenone and a preparation method thereof. Background technique [0002] Water-dispersible granules are a new type of pesticide formulation developed in Europe and the United States in the 1980s. The International Federation of Pesticide Industry Associations (GIFAR) defines it as: granules used after disintegration and dispersion in water. Water-dispersible granules are mainly composed of active ingredients of pesticides, dispersants, wetting agents, binders, disintegrants and fillers, etc., with a particle size of 200μm-5mm, which will quickly disintegrate and disperse after entering water to form a high-suspension dispersion system; Water-dispersible granules cause little or no dust (when in use), thereby reducing toxicity during operation; water-dispersible granules do not flow, making metering more conveni...
