Problems solved by technology

[0006] Chlorpyrifos, also known as chlorpyrifos, is an acetylcholinesterase inhibitor and a phosphorothioate insecticide. It has contact killing, stomach poisoning and fumigation effects, and is effective against lepidopteran pests, planthoppers, leafhoppers, armyworms, and aphids. etc. have good control effects, but the cost of single use of chlorpyrifos to control rice planthopper is high, and there are few alternative varieties of highly toxic pesticides in the production of pollution-free rice. There is a greater risk of drug-induced
[0007] The patented pesticide emulsifiable concentrate preparation (CN101731204A) discloses the preparation of a 10% chlorpyrifos and beta-cypermethrin pesticide emulsifiable concentrate. The emulsifier used is commercialized TG-2201, the cosolvent is dehydrated alcohol, and glycerol is used as a solvent instead of toluene or as The emulsifiable concentrate preparation with toluene as a solvent solves the toxic and side effects caused by the large-scale use of toluene and xylene, but the total content of pesticide active ingredients in the preparation is only 10%

Embodiment 1

[0031] The emulsifiable concentrate compounded with beta-cyhalothrin and chlorpyrifos is composed of the following components by weight: beta-cyhalothrin 1%, chlorpyrifos 50%, compound emulsifier 22%, N,N-dimethyldecanamide 10%, the remainder is dimethyl carbonate;

[0032] The weight ratio of phenethylphenol polyoxyethylene ether sulfate, alcohol ether carboxylate and PEG-80 sorbitan laurate in the composite emulsifier is 1:5:5.

[0033] The preparation method comprises the following steps: adding the metered high-efficiency cyhalothrin and chlorpyrifos, N,N-dimethyl decylamide and dimethyl carbonate into the mixing kettle and stirring to dissolve them, and then adding phenethylphenol polymer. Oxyethylene ether sulfate, alcohol ether carboxylate, PEG-80 sorbitan laurate, supplemented with dimethyl carbonate, turned on the mixer, stirred evenly, filtered, and passed the quality inspection.

Embodiment 2

[0035] The emulsifiable concentrate compounded with beta-cyhalothrin and chlorpyrifos is composed of the following components by weight: beta-cyhalothrin 6%, chlorpyrifos 20%, compound emulsifier 18%, N,N-dimethyldecanamide 15%, the remainder is dimethyl carbonate;

[0036] The composite emulsifier is composed of phenethylphenol polyoxyethylene ether sulfate, alcohol ether carboxylate, PEG-80 sorbitan laurate, and the phenethylphenol polyoxyethylene ether sulfate, alcohol ether The weight ratio of carboxylate to PEG-80 sorbitan laurate was 1:1:1.

[0037] Preparation method: same as Example 1.

Embodiment 3

[0039] The emulsifiable concentrate compounded with beta-cyhalothrin and chlorpyrifos is composed of the following components by weight: beta-cyhalothrin 6%, chlorpyrifos 30%, compound emulsifier 24%, N,N-dimethyldecanamide 10%, the remainder is dimethyl carbonate;

[0040] The composite emulsifier is composed of phenethylphenol polyoxyethylene ether sulfate, alcohol ether carboxylate, PEG-80 sorbitan laurate, and the phenethylphenol polyoxyethylene ether sulfate, alcohol ether The weight ratio of carboxylate and PEG-80 sorbitan laurate was 1:2:5.

[0041] Preparation method: same as Example 1.

Abstract

The invention discloses efficient cyhalothrin-chlopyrifos compound missible oil as well as a preparation method and application thereof, and belongs to the field of a pesticide formulation. The efficient cyhalothrin-chlopyrifos compound missible oil is prepared from the following ingredients in percentage by weight: 1 to 6 percent of efficient cyhalothrin, 20 to 50 percent of chlopyrifos, 1 to 25percent of compound emulsifying agents, 1 to 15 percent of cosolvents and the balance of solvents. The compound emulsifying agents are prepared from phenethyl phenol polyoxyethylene ether sulfate, alcohol ether carboxylate, PEG-80 sorbitan laurate according to the weight ratio of 1:(1 to 5) :(1 to 5). The efficient cyhalothrin-chlopyrifos composite missible oil has the advantages that the preparation ingredient system is reasonable; the emulsification effect is good; the environment pollution is reduced; the prevention and control effect on rice planthopper is good; the pest drug resistance can be delayed.

Description

technical field [0001] The invention relates to the field of pesticide formulations, in particular to a high-efficiency and environment-friendly alpha-cyhalothrin and chlorpyrifos compound emulsifiable concentrate and a preparation method and application thereof. Background technique [0002] EC is one of the basic formulations of pesticides. It is a homogeneous transparent oily liquid prepared by dissolving the original pesticide drug in an organic solvent according to a certain proportion, and then adding a certain amount of pesticide special emulsifier, which can form a relatively stable emulsion with water. This oily liquid is called emulsifiable concentrate . [0003] Compared with other pesticide formulations, EC has the following characteristics: EC has a wider adaptability to the original pesticide. Pesticide technical drugs, including solid or liquid pesticides, are mostly insoluble or insoluble in water, but easily soluble in organic solvents such as xylene. A c...
