Embodiment 1

[0027] Embodiment 1. The development and application of fatty acid methyl ester in pesticide preparation as environment-friendly solvent is used in emulsifiable concentrate (EC), and each component and mass percent are as follows:

[0028]

[0029] Preparation method: Accurately weigh clethodim, calcium dodecylbenzenesulfonate, styrylphenyl polyoxyethylene ether, stabilizer, and fatty acid methyl ester according to the required weight, and stir and circulate at a stirring speed of 800-1900rpm , The cycle time is 60-120min. After all the materials are mixed evenly, they will be sampled and inspected. If they pass the test, they can be packaged and put into storage.

Embodiment 2

[0030] Embodiment 2. The development and application of fatty acid methyl esters in pesticide formulations as an environmentally friendly solvent is used in dispersible oil suspensions (OD), and each component and mass percentage are as follows:

[0031]

[0032] Preparation method: Stir and mix fatty acid methyl ester, fatty alcohol polyoxyethylene ether, and calcium dodecylbenzenesulfonate evenly, add nicosulfuron-methyl and organic bentonite, and stir and circulate at a stirring speed of 800-1900rpm, with a cycle time of 60-120min. After all the materials are mixed evenly, they are put into a sand mill for grinding, and when the particle size of the materials reaches D(90)=3-5 μm, they are sampled and inspected, and can be packaged and stored if they pass the test.

Embodiment 3

[0033] Embodiment 3. The development and application of fatty acid methyl ester in pesticide preparation as environment-friendly solvent, is used in water emulsion (EW), and each component and mass percent are as follows:

[0034]

[0035]

[0036] Preparation method: Stir and mix chlorpyrifos, solvent oil, and fatty acid methyl ester evenly, add styrene phenol formaldehyde resin polyoxyethylene polyoxypropylene block polyether, castor oil and ethylene oxide addition condensate and mix evenly as the oil phase Standby; stir and mix polystyrene phenyl ether phosphate, carthone, organosiloxane, propylene glycol, xanthan gum, and deionized water evenly as the water phase for standby; slowly add the above oil phase to the water phase under shearing state After finishing, continue to shear and homogenize. When the particle size is less than 1 μm, take a sample and test it. If it is qualified, it can be packaged and put into storage.

Abstract

The invention belongs to the technical field of farm chemicals and discloses development and application of fatty acid methyl ester serving as environment-friendly solvent in pesticide preparations. The fatty acid methyl is adopted for replacing high-toxicity solvents in massive use at present. The fatty acid methyl which serves as the environment-friendly solvent is directly added in production of the pesticide preparations and capable of dissolving and dispersing active ingredients of pesticides, and after the fatty acid methyl ester is combined with other additives, qualified pesticide preparation products can be made by stirring, mixing, shearing or grinding. The fatty acid methyl ester is applicable to all pesticide products such as mineral pesticides, biological pesticides, chemical synthetic pesticides and the like.

Description

technical field [0001] The invention relates to the technical field of pesticides, specifically the development and application of fatty acid methyl esters in pesticide preparations instead of highly toxic organic solvents. The invention is applicable to all pesticide products such as mineral source pesticides, biological source pesticides, and chemically synthesized pesticides. Background technique [0002] Pesticides are used to kill insects, fungi, and other organisms that harm crop growth. The earliest pesticides used were DDT, BCH, etc. They can eliminate pests in large numbers. However, they have good stability, can exist in the environment for a long time, and accumulate continuously in animals, plants and humans, so they are eliminated. Later, organophosphorus pesticides, such as dichlorvos, were used instead of the original pesticides. However, they contain phosphorus, which can easily cause eutrophication of aquatic organisms. [0003] With the increasing awaren...
