Agricultural insecticide and acaricide including dimethyl disulfide

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...

[0002] At present, due to the emergence of pest resistance, the control efficiency of most pesticide varieties has declined, and pests have become rampant again.

Acarids form the fastest resistance among various pests. At present, the varieties with better effect on preventing and controlling harmful mites are mainly pyridaben, dicofol, etc. However, due to the development of a large number of single agents or Mixed formulations, combined with the continuous use of single doses by farmers over the years without rotation with other species, have led to the development of resistance in pest mites
