Effect test

experiment example 1

[0026] Choose the recipe below:

[0027] Beta-cyfluthrin 1%

[0028] Toluene 2%

[0029] n-Butanol 4%

[0030] OP-7 2%

[0031] QK-7 10%

[0032] water to 100%

[0033] During production, dissolve the active drug of beta-cyfluthrin with toluene and n-butanol, add OP-7 and QK-7 emulsifiers, stir well, then slowly add the remaining water, and continue to stir for 15 to 20 minutes to obtain a homogeneous transparent liquid, namely A 1% beta-cyfluthrin microemulsion was obtained. The microemulsion of the present invention is diluted 1000 times of liquid, and the prevention and control effect of the wheat ear aphid is 95.8% one day after the drug is applied.

Embodiment 2

[0035] Choose the recipe below:

[0036] Beta-cyfluthrin 2.5%

[0037] Toluene 5%

[0038] Ethanol 5%

[0039] Azone 1.5%

[0040] Butanobuterol 5%

[0041] Butanol 5%

[0042] QK-7 15%

[0043] No. 700 2%

[0044] water to 100%

[0045] The preparation method was the same as in Example 1 to obtain 2.5% beta-cyfluthrin microemulsion. The microemulsion of the present invention has a control effect of 94.1% after 2000 times of dilution of the drug for preventing and controlling diamondback moth.

Embodiment 3

[0047] Choose the recipe below:

[0048] Beta-Cyfluthrin 5%

[0049] Toluene 8%

[0050] Ethanol 4%

[0051] n-Butanol 5%

[0052] Rapid Penetrant T 5%

[0053] QK-7 emulsifier 17%

[0054] No. 601 2%

[0055] Urea 5%

[0056] water to 100%

[0057] The preparation method was the same as in Example 1 to obtain 5% lambda-cyfluthrin microemulsion. The microemulsion of the present invention has a control effect of 96.0% after being diluted 5000 times with the drug for preventing and controlling cabbage worm.

Abstract

An effective insecticiding and miticiding microemulsion is proportionally prepared from beta-cyfluthrin, emulsifier, solvent, synergistic assistant, stabilizer and water through dissolving, adding others, and stirring while slowly adding residual water until it becomes transparent.

Description

technical field [0001] The invention relates to a new dosage form of high-efficiency-cyfluthrin microemulsion, in particular high-efficacy-cyfluthrin microemulsion and a production method thereof. Background technique [0002] Beta-cyfluthrin, also known as Baist, English name Naythroid, CA subject index name and CAS accession number: cyano(4-fluoro-3-phenoxyphenyl)methyl-3-(2,2-dichloroethenyl)-2,2-dimethylcyclopropanecarboxylate( 9CI) [68359-37-5]. [0003] Chemical formula: [0004] Molecular weight: 434.3. The pure product is white crystal and tasteless. Beta-cyfluthrin microemulsion is a transposition product of cyfluthrin, so it is more effective than cyfluthrin. The product has the characteristics of high efficiency, broad spectrum, moderate toxicity, low residue, long-lasting effect, good quick-acting, and low resistance. , fruits and vegetables, tobacco, tea and other crop pests, the prevention and control of harmful mites, once used as the first choice of py...
