Embodiment 1

[0024] Example 1: Combine 5kg of dimethyl disulfide original drug (content above 99.5%) and 945kg of solvent (biodiesel, xylene, methanol, ethanol, dimethylformamide, dimethyl sulfoxide, mineral spirits, vegetable oil) Any one or more of the mixture in any ratio) is thoroughly mixed, and then 50kg of emulsifier (calcium alkylbenzene sulfonate, polyoxyethylene fatty acid ester, sorbitan fatty acid ester, fat Alcohol polyoxyethylene ether, castor oil polyoxyethylene ether, nonylphenol polyoxyethylene ether or a mixture composed of more than one in any proportion), after fully stirring and uniformly, the preparation of 1000kg of the present invention The agricultural acaricidal and insecticidal composition containing dimethyl disulfide.

Embodiment 2

[0025] Example 2: Dissolve 5.1 kg of abamectin powder (above 95%) in 854.9 kg of solvent. After fully dissolving, add 50 kg of dimethyl disulfide, mix well and add 90 kg of emulsifier. Then, it is fully stirred uniformly to obtain 1000 kg of the agricultural acaricidal and insecticidal composition containing dimethyl disulfide according to the present invention.

Embodiment 3

[0026] Example 3: Dissolve 110 kg of pyridaben original powder (with a content of more than 90%) in 725 kg of solvent. After fully dissolving, add 45 kg of dimethyl disulfide. After mixing uniformly, add 120 kg of emulsifier, and then fully Stir uniformly to obtain 1000 kg of the agricultural acaricide and insecticide composition containing dimethyl disulfide according to the present invention.

Abstract

The miticide and pesticide composition containing dimethyl disulfide as one kind of pesticide consists of dimethyl disulfide 0.1-15 wt%, emulsifier 3-20 wt%, and solvent 65-95 wt%; or consists of dimethyl disulfide 0.1-15 wt%, effective component A 0.1-40 wt%, emulsifier 5.0-20 wt%, and solvent 40-90 wt%. The effective component A is at least one of abamectin, pyridaben, diafenthiron, propargite and dicofol; the emulsifier is calcium alkyl benzene sulfonate, polyoxyethylene fatty ester, etc; and the solvent is biodiesel oil, xylene, methanol, etc. The miticide and pesticide composition has the features of high safety, low toxicity, less residue, low cost, high efficiency and broad pesticidal spectrum, and may be used in preventing and controlling mites of crop.

Description

Technical field [0001] The present invention relates to pesticides, in particular to an agricultural acaricidal and insecticidal composition containing dimethyl disulfide. Background technique [0002] At present, due to the emergence of pest resistance, the control effect of most pesticide varieties has declined, and pests have become rampant again. The mites form the fastest resistance among various pests. At present, the varieties with better effects on pest control are mainly pyridaben, dicofol, etc. However, in recent years, various manufacturers have developed a large number of single or Mixed formulations, coupled with the fact that farmers have continuously used the drug as a single agent for many years without rotating it with other species, resulting in pest mites becoming resistant to pesticides. Originally, there are very few high-efficiency pesticides used on harmful mites. Coupled with the development of resistance, there are only a handful of ideal acaricides on th...
