Embodiment 1

[0030] Example 1: Weigh 5.0 grams of triflumuron, 3.0 grams of acrylic acid copolymer salt, 5.0 grams of sodium lignosulfonate, 5.0 grams of pull open powder BX, 8.0 grams of ammonium sulfate, 7.0 grams of starch, and 4.0 grams of disodium hydrogen phosphate , 45.0 grams of kaolin, 16.0 grams of bentonite, and 1.0 grams of carboxymethyl cellulose. After mixing evenly, they are pulverized into powder by an ultra-fine jet mill, then granulated, dried, and sieved. Packing, so as to obtain 5% siflumuron water-dispersible granules. Using 1000-1500 times of the preparation to carry out drug efficacy test, the control effect on American white moth is 95.35%-98.58%, and the control effect on gypsy moth is 93.35%-96.58%.

Embodiment 2

[0031] Example 2: Weigh 10.0 grams of triflumuron, 5.0 grams of acrylic acid copolymer salt, 3.0 grams of sodium lignosulfonate, 3.0 grams of sodium lauryl polyoxyethylene ether sulfate, 8.0 grams of ammonium sulfate, 6.0 grams of starch, dihydrogen phosphate 4.0 grams of sodium, 42.0 grams of kaolin, 12.0 grams of bentonite, 6.0 grams of white carbon black, 1.0 grams of carboxymethyl cellulose, after mixing evenly, pulverize into powder by ultra-fine jet mill, then granulate, dry and sieve After sampling and analysis, if it is qualified, it can be packaged, so that 10% siflumuron water-dispersible granule is obtained. Using 2000-3000 times of the preparation to carry out drug efficacy test, the control effect on the American white moth is 95.62%-98.63%, and the control effect on the gypsy moth is 93.26%-96.65%.

Embodiment 3

[0032] Embodiment 3: Take by weighing 20.0 grams of triflumuron, 5.0 grams of naphthalenesulfonate formaldehyde condensate, 3.0 grams of acrylic acid homopolymer salt, 3.0 grams of sodium dodecylbenzenesulfonate, 5.0 grams of ammonium sulfate, 6.0 grams of starch, Disodium hydrogen phosphate 5.0 g, kaolin 40.0 g, bentonite 12.0 g, carboxymethyl cellulose 1.0 g, after mixing evenly, pulverized into powder by ultra-fine jet mill, then granulated, dried, sieved and sampled Analysis, qualified can carry out packing, so just obtain 20% triflulumuron water-dispersible granule. Using 4000-5000 times of the preparation to carry out drug efficacy test, the control effect on American white moth is 95.05%-98.56%, and the control effect on gypsy moth is 93.40%-96.36%.

Abstract

The invention relates to an agricultural insecticide, which is a water dispersible granule taking triflumuron as effective components and is used for preventing and controlling coleoptera, diptera andlepidoptera in corns, cottons, forests, fruits and soybeans. The triflumuron water dispersible granule comprises the following components in percentage by weight: 0.1 to 90.0 percent of triflumuron,1.0 to 8.0 percent of dispersant, 1.0 to 5.0 percent of wetter, 3.0 to 8.0 percent of disintegrant, 2.0 to 8.0 percent of adhesive, 1.0 to 6.0 percent of stabilizer and 2.0 to 70.0 percent of stuffing. During preparation, the components in a formula are uniformly blended; the mixture is crashed into powder by a superfine pneumatic cracker, and then the powder is palletized, dried and screened to prepare the triflumuron water dispersible granule. The triflumuron water dispersible granule is safe for environment, people and livestock and other beneficial organisms, and is difficult to generate phytotoxicity. In addition, the water dispersible granule has a simple preparation process, safe and convenient use of preparation and no packaging pollution, and is suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to an agricultural insecticide and a preparation method thereof, which is a water-dispersible granule with slumuron as an active ingredient, and is used for preventing and controlling Coleoptera and Diptera on corn, cotton, forest, fruit and soybeans in agriculture. , Lepidoptera pest, the present invention also relates to the preparation method of this agricultural insecticide. Background technique [0002] The traditional dosage forms of pesticides such as emulsifiable concentrates and wettable powders account for about 80% of the total preparations in my country. With the development of dosage form processing, the shortcomings of traditional dosage forms have become more prominent. Old formulations such as emulsifiable concentrates and wettable powders all have serious environmental problems. The organic solvents used in large quantities in emulsifiable concentrates, such as toluene, xylene, methanol, etc., cause inhalation haz...
