example 1

[0056] Add 0.5% of spirodiclofen, 10% of triazophos, 3% of cyclohexanone, 12% of xylene, 4% of polyoxyethylene nonylphenol ether, 7% of castor oil polyoxyethylene ether, and 2% of epoxidized soybean oil Put it into a high-speed shear mixing emulsifier, and get the oil phase after high-speed shearing. Put 3% ethylene glycol, 1% xanthan gum, and deionized water into another high-speed shear mixing emulsifier to make up to 100%. After mixing evenly, the water phase is obtained. Under the condition of shearing, it is added dropwise into the oil phase, and the pH value reaches 5-6 after the addition, and the shearing is continued for 10-30 minutes to obtain a 10.5% insecticidal emulsion in water containing triazophos and spirodiclofen.

example 2

[0058] Spirodiclofen 2%, triazophos 20%, N,N-dimethylformamide 3%, No. 1500 solvent 15%, alkylphenol polyoxyethylene ether 6%, tallow ethoxylated amine salt 4% , 3% of epichlorohydrin is put into a high-speed shear mixing emulsifier, and the oil phase is obtained after high-speed shearing. Add polyethylene glycol 400 3%, magnesium aluminum silicate 2%, and distilled water to 100% in another high-speed shear mixing emulsifier. After mixing evenly, the water phase is obtained. Under the condition of high-speed shearing, it is added dropwise into the oil phase, the pH value is 5-6 after the addition, and the shearing is continued for 10-30 minutes to obtain a 22% insecticidal emulsion in water containing triazophos and spirodiclofen.

example 3

[0060] Spirodiclofen 5%, triazophos 30%, N,N-dimethylacetamide 5%, No. 2000 solvent 15%, fatty alcohol ethoxylate 7%, alkyl phosphorus phosphate 4%, sub Put 3% of triphenyl phosphate into a high-speed shear mixing emulsifier, and obtain an oil phase after high-speed shearing. Add 3% propylene glycol, 3% sodium carboxymethyl cellulose, and distilled water to 100% in another high-speed shear mixing emulsifier. After mixing evenly, the water phase is obtained. Under cutting conditions, add it dropwise into the oil phase, and after the addition, the pH value reaches 5-6 and continue shearing for 10-30 minutes to obtain a 35% insecticidal emulsion in water containing triazophos and spirodiclofen.

Abstract

The invention discloses a compounded insecticidal water emulsion containing triazophos and spirodiclofen and a preparation method thereof. The water emulsion comprises the following components in percentage by weight: 10-40% of triazophos and 0.5-10% of spirodiclofen. The insecticidal water emulsion is prepared by carrying out uniform dispersion on the components through a mechanical stirring or high-speed shearing mixing emulsifier. The product has no drug resistance, is high in pesticide effect, has special effect on citrus mite, and simultaneously can be used for treating lepidoptera insects such as phyllocnistis citrella stainton and papilio xuthus Linnaeus. The insecticidal water emulsion has the advantages that water is used as a dispersing medium, environmental pollution is less, no crystallization occurs after the insecticidal water emulsion is stored for two years, the shelf life is long, the nonflammable property is achieved, the storage and transportation are safe, the production technique is simple, the cost is reduced greatly compared with that of single use of the spirodiclofen, and the like.

Description

Technical field: [0001] The invention relates to a compound insecticidal aqueous emulsion containing triazophos and spirodiclofen and a preparation method thereof. Background technique: [0002] Spirodifen is a non-systemic acaricide, which mainly controls eggs, nymphs and female adults through contact and stomach poisoning. Its mechanism of action is to inhibit fat synthesis in the body of harmful mites, block energy metabolism, and Conventional acaricides have no cross-resistance; their ovum-killing effect is outstanding, and they have good control effects on harmful mites (except male adults) at different developmental stages, and can be used in various growth stages of citrus. It is environmentally friendly and safe for crops. However, spironospirin (mite danger) has the problems of high dilution factor (5000 times to water), high cost, and narrow control area (only effective for mites). [0003] Triazophos is a broad-spectrum insecticide and acaricide, especially has ...
