Abstract

The invention discloses a biopesticide for pest control and a preparation method thereof, and belongs to the technical field of biopesticides. Chinese herbal medicines such as artemisia japonica, fructus evodiae, asafoetide, Chinese wingnut bark, celastrus angulatus, thickfruit millettia seeds or fruits, artemisia rupestris and hairypetal millettia root stems and leaves are selected, and then extracted with ethanol to prepare the biopesticide. Tests show that the biopesticide can be widely applied to prevention and control of injurious insects of vegetables, fruit trees, medicinal materials, flowers, plants and grasslands, and in vitro insects of poultry and livestock, thereby being good in prevention and control effect, non-toxic to people and livestock, and pollution-free to the environment.

Description

A kind of biopesticide of pest control and preparation method

Technical field

The invention belongs to field of pesticides, particularly relate to a kind of biopesticide and preparation method of pest control.

Background technology

At present, the insecticide of prior art mostly is chemical pesticide, and its drug effect is low, and Residual time is long, has a strong impact on crop growth environment and human and livestock health.According to the literature, agricultural chemicals availability is generally 10%, and the residual margin of about 90% in the environment, causes the pollution to environment.A large amount of agricultural chemicals evaporate in air, flow in water body, sedimentation is gathered in soil, pollutes farming animals fishing fruit product, and transfers in human body by the enrichment of food chain, produce harm to human body.The agricultural chemicals of efficient severe toxicity, toxicity is large, and the time residual is in the environment long, when people and animals have eaten the food containing remains of pesticide, accumulation property will be caused poisoning.This kind of harm often just will demonstrate symptom through the accumulation of long period, and it is again the enrichment by food chain, finally just enters human body, not easily Timeliness coverage, and harm is serious.Therefore, development a kind of to indoor flower and crops without poisoning, noresidue, free from environmental pollution and agricultural product, to the biopesticide of people and animals also safety, very important.

Summary of the invention

For solving above technical problem, the object of this invention is to provide a kind of biopesticide and preparation method of prevention and elimination of disease and pests.

The object of the invention is to be achieved through the following technical solutions, this biopesticide is made up of the Chinese herbal medicine of following weight portion: Artemisia japonica 32-38 part, evodia rutaecarpa 40-50 part, asafoetide 23-30 part, Chinese wingnut bark 40-50 part, bitter bark 38-44 part, thickfruit millettia seed or fruit 34-40 part, rock wormwood artemisia 23-32 part, malicious trifoliate jewelvine 40-50 part.

Preferred: Artemisia japonica 35 parts, evodia rutaecarpa 45 parts, asafoetide 27 parts, Chinese wingnut bark 45 parts, bitter bark 41 parts, thickfruit millettia seed or fruit 37 parts, rock wormwood artemisia 28 parts, malicious trifoliate jewelvine 45 parts.

Preparation method: take medicinal material by above weight portion and assort pulverizing, after mixing, the water adding 20L, 12L, 12L respectively endures 3 times, often all over boiling 2L merging filtrate, and with multilayer gauze and Filter paper filtering, the filtrate after heating merges is concentrated into 2L and makes aqua, obtains this biopesticide.

The characteristic of each Chinese herbal medicine: evodia rutaecarpa has good inhibitory or killing effect to ascaris suum, earthworm, leech etc., inhibited to multiple fungi; Asafoetide, Chinese wingnut bark, have desinsection removing toxic substances, itching-relieving action; Bitter bark, heat-clearing and damp-drying drug, removing toxic substances desinsection; Thickfruit millettia seed or fruit, desinsection, attack malicious analgesic effect; Rock wormwood artemisia, malicious trifoliate jewelvine, Artemisia japonica have wider disinsection efficiency.

Effect experiment

Adopt and dilute by the biological pesticide solution made by preferred Chinese medicine part, extension rate is 150-350 times.The Chinese herbal medicine biological agricultural chemicals of this concentration can be used in the extermination of disease and insect pest on greengrocery crop, fruit tree kind, medicinal material, flowers tealeaves and meadow, vaporific even complete stool sprays 1-2 time, can kill the insects such as aphid, cabbage caterpillar, mite class, dish pretty young woman and tortrix moth, two spotted spider mite, trialeurodes vaporariorum; Can be used in growing of the outer sick worm of animal body, in medicine pond, embathe 40 minutes comprehensively, the sick worms such as the external parasite of poultry or livestock, fungi, sarcoptic mite can be killed, prevent the generation that scabies, tinea and leprosy etc. are sick.

The application process of above-mentioned botanical pesticide and result:

In sum: biopesticide drug effect of the present invention plays fast, and drug effect is long, after spraying 1 day, insect inhibiting rate is more than 87%, and after 5 days, insect inhibiting rate is more than 90%, and this biopesticide is based on formula of tagging, and it is auxiliary that suction is killed, and insect does not develop immunity to drugs.

Embodiment
