Monkshood extract, preparation method thereof and use thereof

Abstract

The invention discloses a high-efficiency, low-toxicity and low-residue monkshood extract farm chemical harmonious with environmental and other organisms. The extraction process of the monkshood extract farm chemical comprises the steps of leaching, permeating or refluxing extraction and the like. The monkshood extract farm chemical has a profound significance for both environment protection and prevention of drug resistance in mites. Compared with chemically prepared farm chemicals, the monkshood extract farm chemical has the characteristics and advantages that: monkshood is a natural plant, so the monkshood extract is easy to decompose under natural conditions, safe to environment and surrounding ecological system and free from environmental pollution; the monkshood extract is a multi-ingredient mixture and has a plurality of action sites for tetranychus cinnabarinus, so the tetranychus cinnabarinus cannot generate drug resistance easily; experiments show that the monkshood extract has a remarkable mite killing effect and has a characteristic of high efficiency of farm chemicals; and the extraction of the active ingredients from the monkshood is simple, easy to implement and extremely favorable for industrial production.

Description

field of invention [0001] The invention relates to a plant extract, in particular to an aconite extract and its preparation method and application. technical background [0002] Herbivorous mites have the characteristics of small size, fast reproduction, high population density, and heavy damage. They are recognized as harmful biological communities that are difficult to control. The cinnabar spider mite (Tetranychus cinnabarinus) belongs to Arachnida, Eucaridae, Tetranychidae, and is an important harmful mite that harms fruits, vegetables and greenhouse plants. Chemical pesticides play an important role in controlling harmful mites in agricultural production, protecting crops from damage and ensuring agricultural economic value. However, due to the long-term and extensive use of chemical pesticides, a series of negative effects have been produced, such as increased pest resistance, decreased number of natural enemies, serious environmental pollution, and impaired human hea...
