Problems solved by technology

[0004] But now some bio-pesticides in China are mainly based on EC (using toluene, xylene, etc. as organic solvents), such as azadirachtin EC, matrine EC, avermectin EC, etc. EC has certain advantages: Strong focus, better effect, but at the same time, it is harmful to the ecological environment

[0021] Preparation of total alkaloids of Sophora flavescens: It can be operated according to conventional methods. First, the raw material of Sophora flavescens root is crushed, and the crushed raw material is passed through a 60-mesh sieve, and then placed in an extraction tank, and a mass concentration of 10 times the mass of the raw material is added thereto. 95% ethanol, steam into the interlayer of the extraction tank, heat up to 75-85°C, reflux extraction for 7-8 hours; repeat the extraction 3 times, vacuum filter after each extraction, collect the extract, and use vacuum distillation The extract is heated (the temperature is controlled at 58 degrees, and the pressure is minus 0.085 MPa), and the solvent in the immersion liquid is volatilized and then cooled and refluxed through the condenser. The immersion liquid from which the solvent has been separated is added into n-hexane for stratification, after the stratification, the grease is removed, and the remaining liquid i...

Abstract

The invention relates to a matrine pure plant source pesticide which is characterized by comprising the following components in part by weight: 0.5-5 parts of banlangen, 5-25 parts of active emulsifier, 10-40 parts of organic solvent and 30-60 parts of purified water, wherein the part summation of four substances as basic components is 100. The matrine pure plant source pesticide is prepared from completely natural organic components without chemical pesticides, and has no harm to natural enemies and the environment.

Description

technical field [0001] The invention relates to a pure botanical insecticide and a production method thereof. The product is all natural organic components, does not contain any chemical pesticides, is safe to natural enemies and the environment, and is a matrine pure biological water agent insecticide. Background technique [0002] At present, chemical pesticides are mostly used to prevent and control agricultural pests. With the improvement of people's living standards, the requirements for the quality of agricultural products are higher, not only to eat well, but also to eat healthy. The problem of pesticide residues caused by highly toxic chemical pesticides has increasingly become a hot spot of social concern. Highly toxic pesticides are the core and key to affecting the quality and safety of agricultural products. They not only affect the quality of agricultural products, but also directly endanger the health of the people, and also affect the increase of farmers' inco...
