Abstract

The invention discloses a bactericide prepared from plant extract liquid, relates to a low-toxic bactericide prepared from pure plant extract liquid, and belongs to the technology field of pesticide manufacture. The bactericide is characterized by being composed of following crude drugs in percentage by weight: 20 to 30% of capsicine, 10 to 30% of nicotine, 10 to 30% of azedarachin, 2 to 10% of rotenone, 5 to 20% of fennel, 6 to 22% of croton seed, 2 to 10% of thick-fruited millettia seed, and 2 to 10% of tripterygium glycosides. The bactericide has the advantages of no residual on the crops, safety for human and livestock, no harm to natural enemies of injurious insects, no teratogenic, mutational, and carcinogenic harms to mammal animals, no pollution to environment, and suitability for industrial production, belongs to compound preparations of traditional Chinese medicine, wherein the compound is composed of various active material groups, the bactericide is a pollution-free and environmental product, which has a vast prospect, and is a safest and most vastly applied natural plant pesticide.

Description

Bactericide prepared by one Plant Extracts

Technical field

The present invention relates to low toxicity bactericide prepared by a kind of pure plant extraction liquid, belong to agricultural chemicals manufacturing technology field, say specifically bactericide prepared by a Plant Extracts.

Background technology

For a long time, people utilize the chemical pesticide control damage by disease and insect to obtain remarkable result, but the long-term public hazards that cause of using of chemical pesticide: contaminated environment, soil compaction, residual exceeding standard; Affected people, animal health, chemical pesticide is long-term simultaneously uses rear insect to produce obvious resistance, and preventive effect is descended, and the consumption of agricultural chemicals constantly increases, and has improved cost accounting, has increased the weight of user's burden.

Enhancing along with people's environmental consciousness, the severe toxicity chemical pesticide is progressively being forbidden producing and use, the just worldwide further in-depth of development low toxicity, few noresidue, few nonresistant pesticide species, wherein botanical pesticide is one of important kind of low toxicity, few noresidue, few nonreactive domestic animal.

Although above-mentioned technology has been made good contribution for development low toxicity, few noresidue, few free of contamination pesticide species, but due to above-mentioned kind or because insecticidal spectrum is narrower, or because times liquid is little, quick-acting is inadequate, or, due to the more high reason of price, also exist larger limitation aspect promoting the use of.

Botanical pesticide join mutual technology, its essence is a kind of selection invention, the sophocarpine of public domain and aconitine can have insecticidal action, but what adopt is all the mode of single medicament, a little less than causing the virulence of agricultural chemicals, the longevity of residure is short, cost is high.

Summary of the invention

The bactericide that the object of the present invention is to provide a Plant Extracts to prepare, comply with the development trend of green agriculture, to the person poultry safety, without teratogenesis, mutagenesis, carcinogenic harm, free from environmental pollution to mammal, is suitable for suitability for industrialized production.

For achieving the above object, bactericide prepared by a Plant Extracts of the present invention, its characteristics are: its bulk drug has: it is weight ratio for capsaicine 20～30%, nicotine 10～30%, margosine 10～30%, rotenone 2～10%, fennel 5～20%, crotons 6～22%, thickfruit millettia seed or fruit 2～10%, thunder godvine 2～10%.

Capsaicine is a kind of and pungent vanilla amide alkaloid contained in capsicum;

Nicotine popular name nicotine, be a kind of alkaloid be present in plant of Solanaceae (Solanum), is also the important component of tobacco;

Margosine, argy wormwood, China tree contain margosine, and margosine is the health insect moulting hormones, and interference insect is casted off a skin, and causes insect to produce modal defect, according to the research ladybug, would rather die of hunger also and dare not eat the crop that margosine was processed.The exception margosine can also affect the mating of insect and the growth of ovum.；

Rotenone, can prevent and treat multiple aphid, Oeobia undalis etc.;

Fennel has peculiar fragrance, is bait;

Crotons, call bitter silkworm egg, soaring son, and the thick fruit reticulate millettia of pulse family reticulate millettia platymiscium, be used as medicine with root, leaf and seed.Very toxic, poisoning proterties is vomiting, and stomachache is dizzy, the mucous membrane drying, and breathing is urged, and obnubilation, to paralysis after first excitement of nerve.Be commonly used for eliminating stasis to subdue swelling.Traumatic injury is controlled in external application, fracture.

Thickfruit millettia seed or fruit is called bitter silkworm egg, soaring son, pulse family reticulate millettia platymiscium.Bitter, suffering, hot in nature, large poison, cure mainly and attack malicious pain relieving, eliminating stagnated food to destroy intestinal worms;

Thunder godvine, the Celastraceae tripterygium plant, thunder godvine contains the Multiple components such as alkaloid, sesquiterpenoids, diterpene, triterpene, and wherein Diterpenes is the base main active.The thunder godvine crude extract all has food refusal, poisoning, stomach toxicity paralysis, ovicidal and certain action of contace poison to cabbage caterpillar, diamond-back moth, mythimna separata; Separate from thunder godvine and obtain 9 kinds of compounds in conjunction with the Chemical Decomposition means with determination of activity, be respectively triptophenolide methylether, triptophenolide, triptonide, triptolide, wilforlide A, wilfordine, euonine, wilforgine and wilforine; Study on mechanism shows that triptolide can disturb the release of mythimna separata cholinergic synapse position acetylcholine mediator, suppresses Na+, the k+-ATP enzymic activity, and the endomembrane system of midgut cell is had to certain influence; Velamen of Tripterygium wilfordii powder and root bark extract are raw material, develop 68% velamen of Tripterygium wilfordii powder wetting powder and 25% triperygium wilfordii extractive breast, two kinds of preparations of oil, to the field efficacy of cabbage caterpillar all more than 75%.Product is efficient, low toxicity, can be widely used in the agriculturals such as cabbage caterpillar, diamond-back moth, mythimna separata, vegetable-crop pest-insect improvement.

Bactericide prepared by a Plant Extracts of the present invention, its beneficial effect is: for the pest control of vegetables, fruit tree, tealeaves and Chinese herbal medicine plantation aspect, also there is the effect of killing mosquitos and flies, the effect that also there is control plant virus and bacterium, the growing environment of crops is purified, reduces the generation of damage by disease and insect; The present invention is to the crop noresidue, to the person poultry safety, do not kill natural enemy, without teratogenesis, mutagenesis, carcinogenic harm, free from environmental pollution to mammal, be suitable for suitability for industrialized production, the compound preparation that belongs to Chinese medicine, compound consists of numerous active substance groups, is the nuisanceless environmentally friendly machine with bright prospects, is the agricultural chemical of natural plant that has safety and extensive use most.

Embodiment

Following examples are that the present invention further goes out to set forth.
