Abstract

The present invention relates to the raw material proportion of pesticide and a preparing method thereof. Chaulmoogratree seed, Fructus Xanthii, golden thread, tobacco leaf, tung leaf, potassium nitrate, alum and alkali are used as raw materials, and water is used as solvent. The raw materials are orderly put in the water according to a certain proportion in the temperature rising process of the water, and finally, physic liquor is separated. Three wastes are not drained in the process of preparing the pesticide, the pesticide has no harm for people and livestock in the process of use, and the pesticide especially has obvious disinsection effect on farmland pests, which can achieve 90% to 100%. The pesticide is convenient to prepare, cost is low, and only 3 to 4 yuan are needed when the pesticide is sprayed for 1 mou of farmland once.

Description

A kind of Chinese herbal medicine insecticide and preparation method thereof

The present invention relates to a kind of insecticide that extracts by vegetable material and preparation method thereof.

Use the preparation of organic compound insecticides at present, be at certain environment and container reacts or sex change,, dissolved with organic solvent again through separating, extract or other explained hereafter going out desired finished product with desinsection (bacterium), reach finite concentration, after be emulsified into medicament.But in the process of this insecticides of preparation, the discharging of the three wastes is arranged all generally, polluted environment.In spraying use, through regular meeting people and animals are worked the mischief in addition, intoxicating phenomenon happens occasionally, and equally environment is caused certain public hazards.

The objective of the invention is to change the composition and the production technology of existing insecticide, make three-waste free discharge in this insecticide production process, the finished product of producing is being deposited and is being sprayed in the use and can not cause any harm to people and animals and environment, and insecticidal effect is remarkable.

Chinese herbal medicine and proportioning that the present invention is used are: raw material includes chaulmoogra, the achene of Siberian cocklebur, the coptis, tobacco leaf, paulownia leaf, saltcake, alum and alkali, an amount of water as solvent, its raw material weight proportioning is: 1: 1.0～1.3: 0.7～1.0: 0.3～0.5: 0.4～0.7: 0.3～0.5: 0.7: 0.5～0.7, and the aqueous solvent of using in the preparation process is 80～100 times of the raw material gross weight.Preparation technology of the present invention: at first chaulmoogra, the achene of Siberian cocklebur, the coptis are put into the water of container (being preferably pottery), when being warming up to 85～95 ℃ then, put into tobacco leaf and paulownia leaf, continue to be warming up to 100 ℃ and lasting after 30～50 minutes, add saltcake, alum and alkali, the filtrate of removing slag at last.

Avoided environmental pollution in the preparation organic compound insecticides process with the insecticide of the present invention preparation, deposit and the sprinkling process in can not cause any harm to people and animals, more can not cause social effects of pollution.Especially remarkable especially to the insecticidal effect of insect, by repeatedly experiment, the killing rate of cotton bollworm is reached more than 90% the farmland, aphid is reached more than 98%, can reach 100% to cabbage caterpillar.This insecticide cost is low, and spraying one mu of farmland once only needs 3-4 unit to get final product.

The present invention is realized by following examples:

At first with 100 gram chaulmoogras, 120 restrain the achenes of Siberian cocklebur, and the 80 gram coptiss are put in the container (being preferably pottery), also pour normal-temperature water into container for 50 kilograms simultaneously, when heating container treats that water temperature is raised to about 90 ℃, 50 gram tobacco leaves and 60 gram paulownia leaves are added in the container, continue to be warmed up to 100 ℃, about 40 minutes of temperature fire insulation, with 40 gram saltcake, 50 gram alums and 50 gram alkali are put into container simultaneously again, stop the filtrate of to remove slag slightly, contain bottle inner packing and use.During use, this stoste is put into the water dilution spray, general stoste and water are by 1: 150～200 preparations, and 0.07 hectare sprays the purpose that the 25-50 kilogram but can reach kill pests.
