Embodiment 1

[0020] Example 1: Weigh 8.5kg of kresoxim-methyl, 6.5kg of Jinggangmycin, and then mix it with 10.0kg of benzylphenol polyoxyethylene ether, 4.0kg of octyl phosphate sodium salt, 6.0kg of azone, 4.0kg of ethyl acetate, After 2.5kg of n-butanol is stirred and mixed evenly in a high-speed shearing machine, 58.5kg of deionized water is finally added, stirred and mixed evenly, left to stand for 10 hours, heated to 47°C, and after fully stirred, the pesticide micro emulsion. Using 2800 times liquid of this preparation to carry out the field drug efficacy test, the control effects on wheat sheath blight on the 10th and 16th days after the drug were 88.9%, 86.5%, respectively, and the control effects on the wheat powdery mildew on the 7th and 14th days after the drug The effects were 93.2% and 88.4%, respectively.

Embodiment 2

[0021] Example 2: Weigh 7.0kg of kresoxim-methyl, 6.0kg of Jinggangmycin, and then mix with 7.0kg of benzylphenol polyoxyethylene ether, 6.0kg of octyl phosphate sodium salt, 10.0kg of azone, 6.0kg of ethyl acetate, After mixing 32.5kg of cyclohexanone and 1.5kg of acetone in a high-speed shearing machine, add 24.0kg of deionized water, stir and mix evenly, let stand for 10 hours, heat to 45°C, and stir well. Made of pesticide microemulsion. Using 2400 times of the preparation to carry out the field drug efficacy test, the control effects on wheat sheath blight on the 10th and 16th days after the drug were 86.8%, 83.6%, respectively, and the control effects on the wheat powdery mildew on the 7th and 14th days after the drug The effects were 92.1% and 87.7%, respectively.

Embodiment 3

[0022] Example 3: Weigh 41.0 kg of kresoxim-methyl, 0.8 kg of Jinggangmycin, and then mix it with 3.0 kg of nonylphenol polyoxyethylene ether, 3.5 kg of phenethylphenol polyoxyethylene ether, 4.5 kg of azone, and 5.0 kg of cyclohexanone kg, 3.0kg of ethyl acetate, and 1.5kg of n-butanol were stirred and mixed evenly in a high-speed shearing machine, and finally 37.7kg of deionized water was added, stirred and mixed evenly, left standing for 8 hours, heated to 50°C, and fully stirred After that, the pesticide microemulsion can be made. Using 6000 times liquid of this preparation to carry out the field drug efficacy test, the control effects on wheat sheath blight on the 10th day and 16th day after the drug were 88.6%, 79.5%, respectively, and the control effects on the wheat powdery mildew on the 7th day and 14th day after the drug The effects were 92.2% and 86.5%, respectively.

Abstract

A microemulsion of the mixture of BAS 490F and validamycin is proportionally prepared from BAS 490F, validamycin, emulsifier, penetrant, cosolvent, and deionized water through proportional mixing, stirring, laying aside for 7-14 hr, heating to 38-51 deg.C and stirring.

Description

technical field [0001] The invention relates to a kresoxystrobin pesticide mixing technology, in particular to a krysstrobin-jinggangmycin mixed microemulsion and a preparation method thereof. Background technique [0002] In recent years, developed countries such as the United Kingdom and the United States have imposed increasingly strict restrictions on the use of organic solvents in pesticide preparations. Organic solvents such as xylene and toluene have been banned as solvents for pesticides. This is a challenge to EC preparations. The wettable powder and powder will bring dust pollution, which will promote the development of pesticides along the direction of high efficiency (super efficiency), low toxicity, safety, biological rationality and good environmental compatibility. While strengthening the research and development of new pesticides, people pay more attention to the research and development of pesticide formulations. Among them, the new formulations of pesticide...
