Problems solved by technology

[0005] However, botanical pesticides have disadvantages such as slow efficacy and high frequency of application. In order to increase the efficacy, people usually compound botanical pesticides and chemical pesticides to learn from each other and develop new pesticides with market potential. For example, the application number is "CN200510107500.6" patent "a kind of plant insecticide and its preparation method" mentioned the invention product is prepared from tobacco stem, Boluohui, Naoyanghua and insecticide, among which the content of nicotine is The content is 1.04%-1.18%, the content of sanguinarine is 0.210%-0.241%, the content of chelerythrine is 0

Abstract

The invention discloses a synergistic insecticide of plant source and a preparation method thereof. The insecticide uses nicotine in tobacco stem extracts, sanguinarine and chelerythrine in cordata cordata extracts, and rhodojaponin in Rhododendron molle extracts as the active substances of the insecticide, uses ramie oil, ortho-hydroxybenzoic acid and turpentine as synergistic agents, by adding an appropriate amount of environment-friendly solvent, biologically degradable emulsifiers, anti-freezing agent, thickener and defoaming agent, and using low energy emulsification method to prepare a stable nano water emulsion. The synergistic insecticide of plant source is a pure plant source insecticide, has no chemical pesticide contents, has good preventive effect to aphids and rice planthopper in crops, is safe to human and livestock, causes no pollution to environment, is not prone to trigger resistance to the insecticide, is prone to degrade in natural environment, and the like. The synergistic insecticide of plant source has huge application and promotion value in organic agricultural productscultivation, and is an ideal novel green insecticide.

Description

technical field [0001] The invention belongs to the field of botanical pesticide development, and in particular relates to a botanical synergistic compound insecticide and a preparation method thereof. Background technique [0002] For a long time, due to the extensive use of chemical pesticides in production to ensure the yield and quality of agricultural products, their high toxicity and high residues have put a huge pressure on the ecological environment, and caused some pests to develop resistance quickly, forcing people to further increase The amount of pesticides is used, which in turn causes the residues of chemical pesticides in agricultural products to seriously exceed the standard, causing great harm to people, livestock and the environment. Therefore, the development and utilization of pesticide resources that are environmentally compatible and harmless to humans are increasingly favored by various regions. [0003] With the deepening of pesticide research, botan...
