Emulsifying agent having stabilizing effect in clethodim emulsifiable concentrates and preparation method thereof

Abstract

The invention discloses an emulsifying agent having a stabilizing effect, which is one or a mixture of several of polyoxyethylene lauryl ether, polyoxyethylene nonyl phenyl ether, alkylaryl polyethenoxy ether, polyoxyethylated fatty acid, epoxy chloropropane, PO-EO block polyether, alkylphenol polyoxyethylene formaldehyde condensation product, calcium dodecyl benzene sulfonate, dodecyl benzenesulfonic acid, 2,6-di-tert-butyl-4-methyl phenol and tween-80. By adopting a method of combining a particular stabilizer with a reasonable formula, the problem of high decomposition rate after the clethodim is stored can be solved; and the characteristics are stable, the clethodim is free from having the layering and precipitation problems during the storage process, and the dilution stabilization of the emulsifible concentrates is qualified. The emulsifying agent is particularly suitable for preparing clethodim emulsifiable concentrates. By utilizing the clethodim emulsifiable concentrates which is prepared by the emulsifying agent having the stabilizing effect, the resource can be saved, so the clethodim can be maximally used; and the clethodim emulsifiable concentrates which is prepared by the emulsifying agent having the stabilizing effect have an excellent effect on preventing the gramineous weed, have no residual influence on the aftercrop crops and have good safety.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to an emulsifier for stabilizing clethodim emulsifiable concentrate and a preparation method thereof. Background technique [0002] The production of herbicides has continued to maintain a strong growth trend in my country in recent years, and the growth rate far exceeds that of other types of pesticides. The proportion of herbicides in pesticides is also close to 50%. The area of ​​chemical weeding is increasing at a rate of 30 million mu per year. At present, it has reached 600 million mu times, and the herbicide market will expand to more than 70% of the national pesticide market in the next few years. [0003] Domestically produced herbicide varieties are relatively old and relatively small, and dryland weed damage is becoming more and more prominent in production. Farmers have an urgent demand for dryland herbicides, especially selective herbicides. Secondly, the current use ...

AI Technical Summary

Problems solved by technology

Various market surveys and field drug efficacy results surveys over the past decades have shown that some of the currently processed pesticide preparations have serious loss of active ingredients during the 2-year storage period; the product has low penetration, and more than 95% of the pesticides will not work after field spraying , the loss and volatilization of pesticides that do not work will cause pollution to the atmosphere, soil, water quality, and even the entire ecological environment

As a result, pesticide companies often increase the content in order to pass the product within the guarantee period, resulting in a great waste of resources
