Embodiment 1

[0020] Embodiment 1: Take by weighing chlorantraniliprole 60.0kg and azadirachtin 0.1kg, then with alkylphenol polyoxyethylene ether phosphate 5.0kg, octyl phosphate sodium salt 3.0kg, butyl glycidyl ether 5.0kg Stir and mix with isoamyl alcohol 3.5kg in a high-speed shearing machine, then add 23.4kg of deionized water, stir and mix evenly, let it stand for 10 hours, heat to 55°C, and after fully stirring, it can be made into a microemulsion. The formulation was diluted with water to carry out the field drug efficacy test, and its 4800-fold solution had 87.5% and 84.1% control effects on cabbage aphids on the 7th and 14th days after the application of the drug, and 87.5% and 84.1% on the 5th and 10th days after the application of the rice planthopper. The control effects were 88.1% and 85.2%, respectively, and the control effects on rice white-backed planthopper were 90.0% and 88.8% on the 6th day and 12th day after using the drug.

Embodiment 2

[0021] Embodiment 2: take by weighing chlorantraniliprole 44.0kg and azadirachtin 0.6kg, then with alkylphenol polyoxyethylene ether phosphate 2.0kg, nonylphenol polyoxyethylene ether 2.5kg, natural carboxylate 1.5kg , 2.0kg of octyl phosphate sodium salt, 5.0kg of butyl glycidyl ether and 5.5kg of isoamyl alcohol were stirred and mixed in a high-speed shearing machine, and then 36.9kg of deionized water was added, stirred and mixed evenly, and left to stand for 11 hours , heated to 52 ° C, fully stirred, it can be made into a microemulsion. The preparation was diluted with water to carry out the field drug efficacy test, and its 4800-fold liquid was 89.5% and 86.1% respectively on the 7th day and 14th day after the application of the drug against the cabbage aphid, and 89.5% and 86.1% respectively on the 5th day and the 10th day after the application of the drug to the rice planthopper. The control effects were 89.0% and 86.7%, respectively, and the control effects on rice wh...

Embodiment 3

[0022] Embodiment 3: take by weighing chlorantraniliprole 0.1kg and azadirachtin 25.0kg, then with alkylphenol polyoxyethylene ether phosphate 5.0kg, nonylphenol polyoxyethylene ether 7.5kg, sulfosuccinic acid secondary 8.0kg of octyl ester sodium salt, 7.0kg of azone, 4.0kg of butyl glycidyl ether and 8.0kg of acetone were stirred and mixed evenly in a high-speed shearing machine, and finally 35.4kg of deionized water was added, stirred and mixed evenly, and left to stand for 8 Hours, heated to 56 ° C, fully stirred, can be made into a microemulsion. The preparation was diluted with water to carry out the field drug efficacy test, and its 3500 times solution had 93.5% and 90.3% control effects on cabbage aphids on the 7th and 14th days after the application of the drug, and 93.5% and 90.3% on the 5th and 10th days after the application of the rice planthopper. The control effects were 92.3% and 89.2%, respectively, and the control effects on rice white-backed planthopper were...

Abstract

The invention discloses an insecticidal microemulsion compounded by chlorantraniliprole and azadirachtin and a preparation method thereof, wherein the microemulsion comprises the following compounds according to weight percentages: 0.1-60% of chlorantraniliprole, 0.1-25% of azadirachtin, 3-22% of emulsifier, 2-16% of penetrant, 1-15% of stabilizer, 2-20% of cosolvent and 22-72% of de-ionized water by weight; the preparation method comprises the following steps: putting the chlorantraniliprole, azadirachtin, emulsifier, penetrant, stabilizer and cosolvent into a high speed shearer, stirring to mix uniformly, adding the de-ionized water, stirring to mix uniformly, standing for 3-14h, heating to 47-63 DEG C and stirring uniformly to obtain the microemulsion. The microemulsion has obvious prevention and treatment effect on rice fulgorid, aphid and sogatella furcifera and use water as substrate, thereby overcoming the shortage that the missible oil preparation uses the toxic solvent such as dimethylbenzene. The invention is safe to the environment, human, poultry and other beneficial organisms, and does not generate chemical injury easily.

Description

technical field [0001] The invention relates to insecticide compounding technology, in particular to a compound insecticidal microemulsion of chlorantraniliprole and azadirachtin 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 shortcomings ...
