The raw materials of the pesticide are chaulmoogra, achene of siberian cocklebur, rhizome of Chinese gold-thread, tobacco leaf, leaves of tung tree, nitre, alum and soda. The water is used as solvent. In accordance with a specific compounding ratio, the above raw-materials are put in proper order into the water during warm-up of the water, at last the medicinal liquid is separated out. There are no 'three wastes' in the preparation course, there is no harm to man and animal while applying it, the insecticidal result is obvious and can come up to 90-100%, the preparation process is simple and the cost is low.

Description

A kind of Chinese herbal medicine insecticide and preparation method thereof

The present invention relates to a kind of raw material proportioning and preparation method of agricultural chemicals.

The preparation of use organic compound insecticides at present is at certain environment and container reacts or sex change, through separating, extraction or other explained hereafter go out desired finished product with desinsection (bacterium), dissolved with organic solvent, reaching necessarily has several concentration, after be emulsified into medicament again.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 non-waste-emission 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 desinsection is put fruit significantly.

Chinese herbal medicine and proportioning that the present invention is used are: raw material includes chaulmoogra, the achene of Siberian cocklebur, coptis root, tobacco leaf, paulownia leaf, nitre, alum and alkali, an amount of water as solvent, its raw material 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, coptis root 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 out temperature after 100 ℃ and lasting 30～50 minutes, add nitre, alum and alkali, the filtrate of removing slag at last.

At first prepare insecticide and avoided environmental pollution in the preparation organic compound insecticides process with the present invention.Next be deposit and the sprinkling process in can not cause any harm to people and animals, can not cause social effects of pollution.Importantly remarkable especially to the insecticidal effect of insect, by to repeatedly experiment, the killing rate of cotton sandfly worm is reached more than 90% than the large tracts of land agricultural agency, 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 manages by following examples are real:

1, at first with 100 gram chaulmoogras, the 120 gram achenes of Siberian cocklebur, 80 gram coptis roots 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 rises 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, again with 40 gram nitre, 50 grams are by alum and 50 gram alkali, put into container simultaneously, stop slightly and can remove slag, filtrate is contained bottle inner packing and is used.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 can reach kill pests.
