Problems solved by technology

[0005] Chlorantraniliprole and natural pyrethrin products currently used in the domestic and foreign pesticide markets have deficiencies. Natural pyrethrins are mainly emulsifiable concentrates, and the dosage form of chlorantraniliprole insecticide products is mainly suspension concentrates. There is a disadvantage that the dosage form of the product is relatively single
At present, there is no report on the compound microemulsion of chlorantraniliprole and natural pyrethrins

Embodiment 1

[0024] Embodiment 1: Take by weighing chlorantraniliprole 45.0kg and pyrethrin 0.2kg, then with nonylphenol polyoxyethylene ether 12.0kg, dioctyl sodium sulfosuccinate 3.0kg, disodium hydrogen phosphate 2.5kg and After 6.0kg of isoamyl alcohol was stirred and mixed evenly in a high-speed shearing machine, 31.3kg of deionized water was added, stirred and mixed evenly, left to stand for 10 hours, heated to 55°C, and fully stirred to prepare a microemulsion. The preparation was diluted with water to carry out a field drug efficacy test. The control effect of its 4800 times solution on the 7th day after the application of the beet armyworm was 92.5%, and the control effect on the 4th day after the application of the cabbage caterpillar was 93.8%.

Embodiment 2

[0025] Embodiment 2: Take by weighing chlorantraniliprole 42.0kg and pyrethrin 0.6kg, then with nonylphenol polyoxyethylene ether 2.0kg, sodium dodecylbenzenesulfonate 6.0kg, octyl phosphate sodium salt 3.0kg , 5.0kg of phenyl glycidyl ether and 5.5kg of ethylene glycol were stirred and mixed evenly in a high-speed shearing machine, and finally 35.9kg of deionized water was added, stirred and mixed evenly, left standing for 8 hours, heated to 52°C, and fully stirred After that, microemulsions can be made. The preparation was diluted with water to conduct a field efficacy test, and the control effect of its 4800-fold solution on the 7th day after the application of the beet armyworm was 89.5%, and the control effect on the 4th day after the application of the cabbage caterpillar was 91.2%.

Embodiment 3

[0026] Embodiment 3: Take by weighing chlorantraniliprole 0.1kg and pyrethrin 30.0kg, then with biphenol polyoxyethylene ether 12.5kg, octyl phosphate sodium salt 1.8kg, organosilicon 810c 4.0kg, propenyl glycidyl ether 6.0kg and 10.0kg of ethyl acetate are stirred and mixed evenly in a high-speed shearing machine, and finally 35.6kg of deionized water is added, stirred and mixed evenly, left to stand for 8 hours, heated to 56°C, and fully stirred to produce Microemulsion. The preparation was diluted with water to conduct a field efficacy test. The control effect of its 3500-fold liquid on the 7th day after the application of the beet armyworm was 93.5%, and the control effect on the 4th day after the application of the cabbage caterpillar was 93.2%.

Abstract

The invention discloses chlorantraniliprole and natural pyrethrin compound insecticidal microemulsion and a preparation method thereof. The compound insecticidal microemulsion comprises the following raw materials in percentage by weight: 0.1 to 45% of chlorantraniliprole, 0.2 to 30% of natural pyrethrin, 4 to 26% of emulsifier, 2 to 10% of penetrant, 2 to 8% of stabilizer, 3 to 16% of cosolvent and 24 to 68% of deionized water. The preparation method comprises the following steps: adding the chlorantraniliprole, the natural pyrethrin, the emulsifier, the penetrant, the stabilizer and the cosolvent into a high-speed shearing machine, stirring and mixing uniformly; adding the deionized water into the mixture, and stirring and mixing uniformly; and then standing for 4 to 10 h, heating to 43 to 60 DEG C and stirring uniformly. The microemulsion not only has obvious effect in preventing and controlling beet armyworms and cabbage caterpillars, but also overcomes the shortcomings of the toxic solvent such as dimethylbenzene used in the missible oil preparation by taking water as substrate; moreover, the microemulsion is safe to the environment, people and livestock and other beneficial living beings and does not cause phytotoxicity easily.

Description

technical field [0001] The invention relates to an insecticide compounding technology, in particular to an insecticidal microemulsion compounded with chlorantraniliprole and natural pyrethrins and a preparation method thereof. Background technique [0002] In recent years, in countries such as the United States, restrictions on the use of organic solvents in pesticide formulations have become increasingly stringent, and xylene has a tendency to be banned in some countries. Therefore, it has become the general trend of pesticide development to develop new liquid preparations with strong safety, green environmental protection and low price to reduce or eliminate these harmful organic solvents. Among them, water-based is one of the leading directions for the development of pesticide formulations, and new pesticide formulations will add new features to pesticides, which can give full play to the functional characteristics of the original drug itself, overcome and make up for the...
