Embodiment 1

[0023] 25 g / L efficient-cyhalothrin emulsifiable concentrate

[0024] 95% Beta-Cyhalothrin Technical 2.63g

[0025] Calcium dodecylbenzenesulfonate (emulsifier) ​​5g

[0026] Castor oil polyoxyethylene ether (emulsifier) ​​5g

[0027] Alkylphenol polyoxyethylene ether (emulsifier) ​​1g

[0028] Ethylene glycol diacetate top up 100g

[0029] Physical and chemical performance test of the preparation: the prepared 25 g / L effective cyhalothrin emulsifiable concentrate is a colorless transparent liquid, and at 30°C, it is diluted 1000 times and left for 2 hours without slick oil precipitation. Stored at 0 ± 1°C for 7 days, and stored at 54±2°C for 14 days, there is no significant change in appearance and dilution stability. After storage at 54±2℃ for 14 days, the decomposition rate of active ingredients is 0.11%.

[0031]

[0032] From the above results, it can be seen that the toxicity of Example 1 to th...

Embodiment 2

[0034] 1.8% Abamectin EC

[0035] 95% Abamectin Technical 1.89g

[0036] Phenylphenol polyoxyethylene polyoxypropylene ether (emulsifier) ​​5.35g

[0037] Sorbitan fatty acid polyoxyethylene ether (emulsifier) ​​7.32g

[0038] Alkylphenol polyoxyethylene ether (emulsifier) ​​1g

[0039] Ethylene glycol diacetate top up 100g

[0040] Physical and chemical performance test of the preparation: The prepared 1.8% abamectin emulsifiable concentrate is a colorless transparent liquid, and at 30°C, it is diluted 1000 times and left for 2 hours without slick oil precipitation. Stored at 0 ± 1°C for 7 days, and stored at 54±2°C for 14 days, there is no significant change in appearance and dilution stability. The decomposition rate is 0.05% when stored at 54±2℃ for 14 days.

[0041]

[0042] From the above results, it can be seen that the flash point of Example 1 is significantly higher, indicating that it is safer and safer for storage and transportation; from the perspective of ...

Embodiment 3

[0044] 40% Phoxim EC

[0045] 91.2% phoxim technical 43.86g

[0046] Propylene glycol block polyether (emulsifier) ​​4g

[0047] Phenylphenol polyoxyethylene polyoxypropylene ether (emulsifier) ​​6g

[0048] Fatty alcohol polyoxyethylene ether (emulsifier) ​​0.5g

[0049] Ethylene glycol diacetate top up 100g

[0050] Physical and chemical performance test of the preparation: The prepared 40% phoxim emulsifiable concentrate is a brown transparent liquid, and at 30°C, it is diluted 1000 times and left for 2 hours without slick oil precipitation. Stored at 0 ± 1°C for 7 days, and stored at 54±2°C for 14 days, there is no significant change in appearance and dilution stability. The decomposition rate is 1.89% when stored at 54±2℃ for 14 days.

[0051]

[0052] By the above test results, it can be found that compared with the phoxim emulsifiable concentrate with xylene as solvent, Example 2 is more toxic to the 3rd instar larvae of the cutworm, and its flash point is signi...

Abstract

The invention discloses environment-friendly pesticide emulsifiable concentrate belonging to the field of pesticides. The environment-friendly pesticide emulsifiable concentrate comprises an active ingredient, a solvent and a surfactant and is characterized in that the solvent is ethylene glycol diacetate and / or ethylene glycol monoacetate. In percentage by mass, the active ingredient accounts for0.1-90%, the solvent accounts for 1-90%, and the surfactant accounts for 1-30%. Ethylene glycol diacetate and / or ethylene glycol monoacetate is used for replacing the traditional solvents toluene andxylene, so that toxic and side effects produced by use of large amount of toluene and xylene are avoided, environmental pollution is reduced, and health hazard on people and livestock is reduced, andthe pesticide emulsifiable concentrate disclosed by the invention belongs to an environment-friendly and novel pesticide. Due to use of the ethylene glycol diacetate and / or ethylene glycol monoacetate, surface tension of pesticide solution can be obviously reduced, so that pesticide liquid drops are more uniform in particle size distribution in an atomization process and are better wetted and distributed on plant surfaces; and bioactivity is better than that of an emulsifiable concentrate preparation taking toluene and xylene as the solvents.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to an environment-friendly pesticide emulsifiable concentrate. Background technique [0002] EC is the most commonly used pesticide formulation. Due to its long history and mature processing technology, EC has many varieties, large output, wide application range, simple process, small equipment investment, simple packaging, and difficult formula development. Small and other advantages, because in this dosage form, the active ingredient exists in a molecular state, so its drug effect is high and its properties are relatively stable. [0003] The solvents in pesticide emulsifiable concentrate preparations are mainly toluene and xylene. The use of these solvents will cause irritation to the skin and respiratory system of the applicator, and organic solvents such as toluene and xylene are toxic to fish, algae and other aquatic organisms. If it is relatively high, it will pose a threat to the ...
