Abstract

The invention provides a preparation method of a plant insecticide. The preparation method comprises the following steps: taking mexican tea herb, herb of hispid hedyotis, common lantana leaves, light yellow sophora root, common monkshood mother root and alpine yarrow herb; adding pure water and decocting; filtering a decocting solution; concentrating a filtering solution to obtain a concentrated solution; adding ethanol and uniformly stirring; standing and filtering; concentrating the filtering solution to obtain paste; mixing largehead atractylodes rhizome, Danshen root, incised notopterygium, divaricate saposhnikovia root, officinal magnolia bark, Szechuan lovage rhizome and astragalus membranaceus; crushing into rough powder; immersing with an ethanol water solution and percolating; collecting a percolating solution; recycling ethanol to obtain a concentrated solution; extracting with diethyl ether and decompressing and recycling an extracting solution to obtain extract; and finally, mixing the obtained paste with the obtained extract, and freezing and drying to obtain the product. The insecticide has the effects that the pesticide effect is rapid, active components are not easy to decompose, the pesticide effect is long and the formula is simple and easy for standardization; the source of raw materials is wide and the cost is low; and the product does not contain any chemical pesticide or component and has no environmental pollution and no residues, and has an extremely great application and popularization value.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a preparation method of plant pesticides. Background technique [0002] Pesticides are an important link in agricultural production and directly affect the economic effects of agricultural production. According to the source, pesticides can be divided into four types: 1. Inorganic and mineral pesticides, such as lead arsenate, calcium arsenate, sodium fluorosilicate and mineral oil emulsion. Such insecticides generally have low drug efficacy and are likely to cause phytotoxicity to crops, while arsenic is highly toxic to humans. Therefore, most of the organically synthesized pesticides have been eliminated. 2. Botanical pesticides. There are about 1,000 kinds of plants in the world that are more or less toxic to insects. Pyrethrum, deer vine and tobacco are widely used. In addition, some plants also contain active substances similar to juvenile hormone, precoc...
