Abstract

The invention discloses a botanical plant protection agent, whose raw material components and parts by weight include: 1-3 parts of litsea cubeba oil, 1-8 parts of azadirachtin, 3-5 parts of silicate, 0.5 parts of surfactant -1 part, 5-10 parts of tackifier and 500-700 parts of water. The preparation method comprises the steps of dissolving the tackifier raw material with water to form a tackifier solution, then emulsifying the litsea cubeba oil and azadirachtin with water, adding the tackifier solution solution and silicate, fully stirring and mixing uniformly to obtain the product . The botanical plant protection agent of the present invention maintains the characteristics of low toxicity, high efficiency, easy degradation, and no residue of botanical pesticides, is not easy to produce drug resistance to pests, does not pollute the environment, and has a good control effect on crops. It is a broad-spectrum new pesticide preparation for pest, sterilization and anti-virus, which can be used alone or/and mixed with common insecticides and pesticides.

Description

technical field [0001] The invention belongs to the technical field of pesticide insecticide and fungicide, and relates to a botanical plant protection agent composed of litsea cubeba oil and azadirachtin and a preparation method thereof. Background technique [0002] Litsea cubeba oil, also known as Litsea cubeba oil, is an essential oil extracted from Litsea cubeba fruit by steam distillation. Litsea cubeba is a kind of Lauraceae plant, which is mainly produced in East Asia. It is planted in large quantities in the provinces south of the Yangtze River in my country. The main component: carbonyl compound (calculated as citral) ≥ 66%. The main component is citral, the content is about 60%-80%. Other ingredients include methylheptenone, citronellal, citronellol, pinene, limonene, 1,8-cineole, camphene, linalool, 2-methyl-2-hexen-6-one , camphor, safrole, nerol, geraniol, terpineol, geranyl acetate, eugenol and p-cymene. Containing more than 26 kinds of chemically active su...
