Botanical insecticide

Abstract

The invention discloses botanical insecticide. The botanical insecticide comprises, by weight, 1 part to 12 parts of Chinese yam, 0.5 part to 3 parts of angled bittersweet, 1 part to 12 parts of fructus cnidii, 1 part to 10 parts of dandelion, 1 part to 5 parts of feverfew, 3 parts to 10 parts of roses, 1 part to 3 parts of herba houttuyniae, 2 parts to 5 parts of acanthopanax, 4 parts to 10 parts of pseudo-ginseng, 2 parts to 5 parts of garlic, 1 part to 3 parts of camphor tree leaves, 1 part to 10 parts of folium artemisiae argyi, 1 part to 4 parts of lavender and 3 parts to 10 parts of orange peel. The botanical insecticide rapidly plays efficacy, active ingredients are not prone to decomposing, the active ingredients are durable in efficacy, the formula is simple and can be easily standardized, the raw materials are wide in source and low in cost, no chemical pesticide ingredients are contained, and the botanical insecticide is free of pollution and residues and has great application and popularization value.

Description

Technical field: [0001] The invention relates to an insecticide, in particular to a botanical insecticide, and belongs to the technical field of insecticides. 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,...

Problems solved by technology

[0004] The same botanical insecticides have the following outstanding disadvantages: 1. Most natural product compounds have complex structures, which are difficult to synthesize or the synthesis cost is too high; 2. The active ingredients are easy to decompose, and the preparation components are complicated and difficult to standardize; Insecticides are slow to exert their efficacy, which leads some farmers to think that the insecticides used are ineffective; 4. The number of sprays is too many, and the residual period is short
