Environment-friendly miticide and preparing method thereof

Abstract

The invention provides an environment-friendly miticide and a preparing method thereof. The miticide is prepared from, by weight, 1-15 parts of fatty alcohol polyoxyethylene ether sodium sulphate, 2-15 parts of coconut diethanolamide, 5-10 parts of sodium dodecylbenzene sulfonate, 0.1-0.5 part of kathon, 5-40 parts of zanthoxylum bungeanum extract, 5-30 parts of pubescent holly root exract, 2-25 parts of potato extract, 60-80 parts of water, 10-70 parts of turpentine, 0.1-5 parts of rotenone, 1-10 parts of a cosolvent, 5-10 parts of an emulsifying agent, 5-15 parts of a natural penetration promoting agent, 0.2-2 parts of a penetrating agent, 0.5-3 parts of ultraviolet absorbing agent, 0.5-3 parts of an antioxidant and 1-5 parts of anti-freezing agent. The miticide is environmentally friendly, effective, free of residues, wide in mite killing range, low in production cost, good in mite killing effect, and good in economic, social and ecological benefit.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a green and environment-friendly acaricide and a preparation method thereof. Background technique [0002] With the development of my country's agricultural modernization and the gradual transfer of agricultural labor force, cultivation methods tend to be large-scale and intensive, and the demand for pesticides has increased significantly. Herbivorous mites have the characteristics of small size, rapid reproduction, short developmental period, small range of action, strong adaptability, high mutation rate, and susceptibility to drug resistance. They are recognized as the most difficult pest group to control. Taking citrus red spider as an example, citrus red spider is the most serious major pest commonly occurring on citrus in my country at present. It mainly damages citrus leaves, branches and fruits. until it withers and falls off. It occurs several generations...

AI Technical Summary

Problems solved by technology

Due to the emergence of drug resistance and the decrease in the number of natural enemy populations, the interval between the application of pesticides to prevent and control citrus red spiders is generally about 15 days, and pesticides need to be applied once every 7 days during the high-incidence period, which increases the labor intensity of fruit farmers and increases production costs. Pesticide residues are increased, and the agricultural ecological environment is damaged. Fruit farmers are often poisoned by pesticides, and consumers are also affected by eating fruits with pesticide residues.
