The present invention discloses a plant pesticide and its production method. It is made up by using several Chinese medicinal materials of hot pepper, areca nut, stemona root, veratrum root, ginko leaf, macleaya cordata and other as raw material, and adopting water or ethyl alcohol extraction process to prepare solution to obtain the invented product. It is a natural pesticide, and its toxic side effect is less.

Description

Vegetable insecticide and production method thereof

The present invention relates to a vegetative insecticide.

Existing crops pesticide is much all having certain murder by poisoning in varying degrees, and is behind the edible residual crop that such insecticide arranged of people, harmful to health.

The object of the present invention is to provide little vegetable insecticide of a kind of toxic and side effect and production method thereof.

Technical solution of the present invention is:

One vegetative insecticide comprises the raw material of weight components:

Capsicum 10～20% betel nuts 10～20%

The tuber of stemona 10～20% black false hellebores 10～20%

Ginkgo leaf 5～15% BOLUOHUIs 5～15%

Calamus 2～10% kuh-sengs 2～10%

Above-mentioned raw materials is made solution through water or alcohol extract.

In the solution of making, also be added with the preservative of solution total amount 0.2～0.5%.

The production method of one vegetative insecticide comprises the following steps: successively

A) raw material with weight components adds water or ethanol (addition is 3～6 times of raw material), puts into water-bath, and hot digestion gets extract:

Betel nut 10～20%, the tuber of stemona 10～20%, black false hellebore 10～20%, ginkgo leaf 5～15%

BOLUOHUI 5～15%, Piao Zi grass 2～10%, calamus 2～10%, kuh-seng 2～10%;

B) capsicum 10～20%, chinaberry fruit stone 2～10% are ground into fine powder, add water or ethanol, hot digestion gets extract; Above-mentioned steps a), b) in each raw material weight sum be 100%.

C) extract 70～88% volumes that will be through a) obtaining with through b) extract 12～30% volume mixture that obtain, get product.

After step c), also add the preservative of solution total amount 0.2～0.5%.

During hot digestion, also carry out reflow treatment in the step a), during hot digestion, also carry out reflow treatment in the step b).

Capsicum, chinaberry fruit stone are ground into 250～400 purpose fine powders in the step b).

Preservative is vitamin C or phytic acid, mannitol.

During use, the product alkene that obtains can be released use.

The present invention is according to the traditional theories of Chinese materia medica of China, draws the elite in the successive dynasties plant pharmacy experience, is raw material with multiple Chinese herbal medicine, and the science compatibility has the advantage natural, that toxic and side effect is little, is a kind of " green " environment-friendly pesticide.Product of the present invention and other plant pesticide, chemical pesticide share, and synergistic effect is arranged.
