Abstract

The invention relates to a plant acaricide suitable for preventing and treating harmful acarids on the economic crops of fruit trees, vegetables and the like, a preparation method and an application thereof. The plant acaricide is a plant source acaricide which is prepared by adding a surfactant, an emulsifying agent, a penetrant, a synergist and the like into beta-amyrin and has the characteristics of high efficiency, low toxicity, low residue, environmental friendliness and the like.

Description

technical field [0001] The invention relates to a new application of β-amyrin, in particular to a new application of β-amyrin in preparing plant acaricides. Background technique [0002] β-Amyrin English name: β-Amyrin, β-Amyrin exists in a free state, and exists in the latex of various rubbers in the form of acetate and palmitate; needle state from ethanol; melting point 197~197.5℃; soluble in acetic acid, ether, benzene and hot ethanol. Soluble in petroleum. It reacts with chromium trioxide to generate β-mycetin. It can be used as a medicine with anti-inflammatory, sedative and anti-tumor effects. Herbivorous mites are important pests in agricultural production. They have a wide distribution range, many harmful hosts, a large area of ​​occurrence, and strong drug resistance. They cause serious losses to agricultural production and are difficult to control. However, there is no report on the application of β-amyrin in the preparation of plant acaricides in the existing ...
