Abstract
Disclosed is a plant pesticide combination, which comprises rheum officinale 0.5-1.5%, rheum officinale phenols 0.05-1.0% and coarse extract of other medicinal plant. The invention can be applied for eradicating insects and bacteria for medicinal plants with highly effectiveness, low toxicity to human and livestock, and no contamination to environment.
Description
Technical field
The invention belongs to field of biological pesticide, be specifically related to the archen Chrysophanol and slightly carry desinsection, the sterilization aqua that is mixed with other medicinal plant.
Background technology
Plant pest is annual causes tremendous loss for crops, vegetables and medicinal plant production, and conventional method is to use chemical pesticide, but chemical pesticide has contaminated environment, and insect easily develops immunity to drugs, the poisonous and environmental pollution to people and animals.Appliable plant is produced the green organic farm products of no pesticide pollution with source pesticide, provides solid foundation for guaranteeing human beings'health and good environment.
Botanical pesticide is to extract from plant, and germ and insect are had anti-smelting effect, to people and animals' low toxicity, noresidue, can also delay the generation of pest resistance to insecticide, is the ideal pesticide type therefore.China has also developed some products in recent years.Rheum officinale and we adopt medicinal plant to be used for the crops deinsectization, crops are had effect still is not reported in desinsection, the sterilization, so we vegetable source pesticide, the bactericide of development are novel plant source desinsection, bactericide.
Summary of the invention
The object of the present invention is to provide a kind of high-efficiency low-toxicity, non-environmental-pollution, to people and animals' low toxicity, archen that again can pesticide-germicide and the composite plant pesticide of other medicinal plant extract.
Rheum officinale is the pesticide-germicide aqua of principal component.
Above-mentioned aqua mainly contains the 0.5-1.5% archen.
Above-mentioned aqua mainly contains the 0.5-1.5 archen and adds auxiliary agent revisal 100%.
Rheum officinale dirt molecular structural formula is:
The described auxiliary agent of above-mentioned aqua is made up of several medicinal plant alcohol extracts and emulsifier, and its percent by volume is: every kind of alcohol extracting medicinal plant extract 10-50% (1ml is equivalent to 0.76 gram crude drug) and emulsifier 10%.
Emulsifier in the described auxiliary agent of above-mentioned aqua can one or both be made into tween JFC, OP-10 and those skilled in the art's emulsifier in common knowledge.Medicinal plant preparation methods such as rheum officinale are similar substantially, can obtain extract with the alcohol extract method.The preparation method of medicinal plant solution such as rheum officinale comprises that raw material is handled to granulate with the cracker powder, raw material powder 50% ethanol is mixed soak then, triple effect jar refluxing extraction and must rheum officinale solution.
Beneficial effect of the present invention and advantage:
It is the natural goods that extracts from medicinal plant that the present invention utilizes medicinal plant main components such as rheum officinale and Chrysophanol, and medicinal plants such as rheum officinale have the pesticide-germicide effect, so the present invention has stronger killing action to insect and the germ of crops.Pesticide-germicide is than wide spectrum, and do not have pesticide resistance, do not contain any harmful medicine composition of learning to farm, and is to people and animals' low toxicity, noresidue, free from environmental pollution.
Embodiment
Production method of the present invention is: the section of herbal raw material rheum officinale, the various Chinese herbal medicines of dried and crushed → extraction (alcohol extracting) → filtration → concentrate → preparation (dropping into by the medicine liquid ingredient content ratio) → stir → filter → basin packing → warehouse-in.
The technological process of production of the present invention:
Airing → section → pulverizing → ethanol immersion liquid → leaching liquor → decompression → concentrate → concentrate → different grouping is excavated → shone in the field autumn composite → can → finished product → packing → warehouse-in.
Compound method of the present invention: with Radix Et Rhizoma Rhei extract A and according to following volume ratio with B medicinal plant extract 10% (1ml be equivalent to 0.76 gram crude drug) C extract (milliliter is equivalent to 2 gram crude drugs) even 10% emulsifier of emulsifier mixture, then that the ABC emulsifier is even, promptly get several medicinal plant pesticide-germicide aquas such as rheum officinale of the present invention.
This test is carried out in China Medical Sciences Academy Medical Plants Institute.
