Pesticide adjuvant

Abstract

The invention provides a pesticide adjuvant, which belongs to the field of pesticides. The pesticide adjuvant is composed of water and surfactant, wherein the surfactant is one or more selected from the group consisting of betaine, ammonium salt, amine oxide, palm kernel diethanolamide, styrylphenol polyoxyethylene ether and N-polyoxyethylated-N-tallow-alkylamine. The pesticide adjuvant has good salt tolerance and can be used both for preparation of a variety of soluble concentrate preparations of paraquat and preparation of a variety of soluble concentrate preparations of diquat and hybrid preparations of paraquat and diquat. Moreover, the pesticide adjuvant has good versatility and can realize processing of a plurality of dosage forms like a variety of aqueous solutions, soluble concentrates and soluble glues of paraquat and diquat by using different amounts of the pesticide adjuvant.

Description

technical field [0001] The invention relates to a pesticide adjuvant, in particular to an adjuvant applied to bipyridyl soluble liquid herbicides such as paraquat and diquat. Background technique [0002] Bipyridyl herbicides were developed in the late 1950s, and there are two important varieties of these herbicides, paraquat and diquat. Paraquat, chemical name: 1,1'-dimethyl-4,4'-bipyridine dichloride, C12H14Cl2N2. Diquat, chemical name: 1,1'-ethylene-2,2'-bipyridine dibromide, molecular formula: C12H12Br2N2. [0003] Bipyridyl herbicides are contact-killing stem and leaf treatment agents, which can be quickly absorbed by leaves and conduct upward in the asymplast, but not downward in the phloem, so they cannot kill the underground parts of weeds. These herbicides inhibit photosynthetic system I and require light to exert herbicidal activity. Bipyridyl herbicides can be quickly and strongly adsorbed by soil colloids, so soil treatment is inactive. These herbicides are m...

AI Technical Summary

Problems solved by technology

At present, domestic and foreign adjuvant companies have done a lot of research on the aqueous and soluble agents of bipyridine herbicides, and there are many adjuvant products on the market, but the adjuvants of paraquat and diquat soluble gel Little research and no related patents

In addition, when the active ingredient of the same pesticide is processed into different dosage forms (such as water, soluble, and soluble gel), or the same dosage form uses different active ingredients of pesticides, it is often necessary to choose different adjuvants. Therefore, bipyridyl herbicide preparations Processing enterprises need to prepare a variety of auxiliaries in actual production to meet the needs of production, and various auxiliaries and dosage forms cannot be mixed, which not only increases the complexity of preparation processing, is not convenient for large-scale production, but also has relatively big waste of resources
