Acaricide and preparation method thereof

Abstract

The invention relates to the technical field of pesticides and discloses acaricide and a preparation method thereof. The acaricide is prepared from the following raw materials in parts by weight: 5 to 10 parts of Canada goldenrod volatile oil, 6 to 11 parts of eupatorium adenophorum extracting liquid, 3 to 6 parts of pistacia chinesis bunge, 15 to 30 parts of daucossterol, 4 to 12 parts of semen torreya, 2 to 10 parts of Chinese prickly ash, 2 to 7 parts of abamectin, 10 to 30 parts of spirodiclofen, 30 to 40 parts of a solvent, 10 to 15 parts of a co-solvent and 1 to 10 parts of an anti-freezing agent. The acaricide provided by the invention has the advantages of low toxicity, environment protection, wide acaricidal spectrum, long lasting period and capability of effectively alleviating drug resistance; invasive species are comprehensively utilized and wastes are changed into valuable things; the acaricide can be used for agricultural prevention and treatment of harmful acarids.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to an acaricide and a preparation method thereof. Background technique [0002] In recent years, due to the unreasonable use of chemical pesticides and the inherent shortcomings of the pesticide itself, such as a single acaricidal spectrum, easy to produce drug resistance, and the toxicity of the chemical ingredients is too strong, etc., these have caused a series of public hazards in the use of pesticides. Such as environmental pollution, human and animal poisoning, killing natural enemies, destroying ecological balance, "3R" (Residue, Resistance, Resurgence) and other serious problems, these adverse effects have attracted widespread attention. On the other hand, the development of synthetic pesticides has low success rate, long period and high cost. Due to the above reasons, when the pesticide industry in various countries in the world is looking for new bio-rational pesticide...

AI Technical Summary

Problems solved by technology

[0003] There are many kinds of acaricides used to prevent and control mites in the market, including highly toxic acaricides such as amidines, organophosphorus, and organochlorines that are not safe for crops; It is a kind of acaricide, but its duration of effect is short. In order to pursue the control effect, it must be used multiple times, and repeated excessive use will easily induce the generation of resistance to insecticides

At present, most of the insecticides used for pest control are selective acaricides, such as pyridaben, dicofol, hexythiazox, abamectin, etc., but the selectivity of insect control is single, based on the current field of pesticides, especially acaricides There are all kinds of problems mentioned above in the use of pesticides. It has become an important topic in the field of pesticides to invent a kind of acaricide with low toxicity, environmental protection, wide spectrum of acaricide and no cross-resistance.

[0004] Although some achievements have been made in the current research on the components of botanical acaricides, most of them are only used for efficacy experiments on a few types of acarids, and the scope of application is limited, and only the control effect is concerned. No further research has been done on issues such as how to mitigate the harm caused by the use of invasive organisms

For example, Chinese patent CN 103548884 A goldenrod oil is used as an acaricide. The acaricide made from Pistacia chinensis in this invention has a good effect on Tetranychus cinnabarinus, but there is no experimental study on resistance to insecticides, and no toxicity experiments on other harmful mites. conduct
