Application of Amino Acid Cyclodextrin Derivatives as Pesticide Synergists

Abstract

The invention discloses the application of amino acid cyclodextrin derivatives as pesticide synergists. The amino acid cyclodextrin derivative of the present invention is obtained by nucleophilic substitution reaction of amino acid or amino acid ester with mono-6-O-(p-toluenesulfonyl)-β-cyclodextrin under alkaline conditions, and is safe and non-toxic , low manufacturing cost; the complexation of amino acid cyclodextrin derivatives with active ingredients of pesticides can increase the solubility of pesticides and have synergistic effects; therefore, it can be used as a pesticide synergist to solve the problem of low solubility and poor efficacy of some pesticides It has the effect of improving the efficacy of pesticides and alleviating the resistance of pests, and can provide candidate adjuvants for the development and improvement of high-efficiency pesticide formulations, which is conducive to the realization of pesticide dosage reduction and efficiency enhancement.

Description

Application of Amino Acid Cyclodextrin Derivatives as Pesticide Synergists technical field The invention belongs to the technical field of pesticides, be specifically related to the application of amino acid cyclodextrin derivatives as pesticide synergists. use. Background technique In the whole growth process of crops, some insect pests can affect the growth of crops, and chemical agents are The most effective way to prevent insects. However, many pesticides and pesticides themselves are almost insoluble in water, and most of them are dissolved in organic solvents. With the large-scale use of pesticides, the pollution caused to the environment cannot be ignored. According to statistics, the use process of conventional pesticides Among them, about 80% of the pesticides directly enter the environment, resulting in a great reduction of natural enemies of pests or other beneficial insects, water pollution, and land pollution. pollution and environmental pollution; im...
