Abstract

The invention belongs to the technical field of pesticides, and in particular relates to a pesticide synergist. The pesticide synergist provided by the invention extracts effective and active strainsfrom paris roots for fermentation, so as to obtain a fermentation product, the paris roots mainly contain active substances such as sterols, fats, amino acids and saponins, actinomycetes can form a close relationship with the paris roots and can be propagated in the inner organization of the paris roots, a large number of the actinomycetes are symbiotic or parasitized into a large number of plants, and active substances of which medicinal components are similar to those of medicinal plants can be extracted through separating and screening of the paris root endophytic actinomycetes with specific medicinal value; the antibacterial active substances have inhibiting and killing effects on pests and plant pathogens, and are high-efficiency, low-toxic and environmentally friendly; and the antibacterial active substances can assist an application of a pesticide, reduce the use amount of the pesticide, improve the agricultural ecosystem, maintain the biodiversity of a plant micro-ecological system and play an important role in maintaining the farmland ecological balance and realizing the sustainable development of agriculture.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a pesticide synergist. Background technique [0002] The development of agriculture is inseparable from pesticides, but while pesticides have made great contributions to agricultural development, they have also brought harm to the natural environment. In recent years, due to the abuse of chemical pesticides, the resistance of pests has increased, leading to an increase in the amount and frequency of pesticide use, further aggravating environmental pollution and ecological damage, causing a vicious circle and seriously endangering human life and health. [0003] It is also a realistic and feasible solution to use various synergists in the application of pesticides to improve the utilization rate of pesticides in the process of spraying, improve the efficacy of pesticides, and reduce the amount of pesticides used. [0004] Pesticide synergist is an adjuvant added to pesticides....
