Abstract

The present invention relates to a preparation process of a biotic broad-spectrum pesticide 'Plant Protection 102' which is prepared by using pure traditional Chinese medicines. The present invention is characterized in that the traditional Chinese herbal medicines, such as grand torreya seed, lightyellow sophora root, hairyvein agrimonia herd, stemona root, euphorbia, calcined alum, belvedere fruit, etc., are adopted, and the biotic broad-spectrum pesticide is prepared in the steps of sorting, pulverization (grinding into fine powder), boil, filtration, precipitation, refiltration, concentration and antiseptic treatment. The pesticide has obvious control efficiency to destructive insects of crops, such as manchurian fruit moths, oriental fruit moths, peach fruit moths, red spiders, scale insects, leaf borers, wheat aphids, cabbage worms of vegetables, etc., and the pesticide has no pollution to environment, and no harm for people and animals; thereby, the pesticide is an ideal pesticide for replacing chemical pesticide and producing nuisance-free agricultural food.

Description

Preparation of wide-spectrum plant pesticide

The preparation method who relates to a kind of nuisanceless green environment protection biological agricultural chemicals broad spectrum pesticide in the time of this.

Agricultural chemicals has critical role in agricultural production.But people find that in production practices chemical pesticide is very harmful to natural environment and human beings'health in recent years.The meeting of " Pesticide Action Network " international organization is pointed out: 60% chemical pesticide has been proved to be and has contained carcinogen, also have 118 kinds of agricultural chemicals can destroy the hormonal balance of human body, the a research report of the United Nations shows, 2,500 ten thousand of chemical pesticide poisonings take place every year in the whole world at least at present, cause nearly 20,000 people's death." Pesticide Action Network " international conference calls upon States to reduce the use chemical pesticide as far as possible, to guarantee the safety of agricultural food product, conservation of nature ecotope.China Ministry of Agriculture has stopped ratifying the registration of acephatemet, the contour malicious organophosphorous pesticide of parathion from 2 000 on July 12,, has cancelled the application registration on fruit tree of parathion-methyl and parathion; And require the various places active development, promote low toxicity, the low-residual biopesticide.At present, develop plant-biological pesticide energetically, progressively the instead of chemical agricultural chemicals is a new revolution on the agricultural chemicals development history.

Aphid, heart-eating worm, two spotted spider mite, star caterpillar, scale insect, cabbage caterpillar etc. are insects common on fruit tree and the crops, and the hairworm area is wide, breeding is fast, harm is big, usually causes heavy losses such as fallen leaves, decayed fruit, crops total crop failure.For a long time acephatemet, parathion, the contour poison of Rogor, high residue chemical pesticide are used in this disease control more; Polluted ecotope, residual exceeding standard, insect pest has produced pesticide resistance.Therefore, country expressly forbids that height poisons the medicine of learning to farm and uses in agricultural production.In recent years Northwest Agricultural University's public nuisance-free agricultural chemicals factory with LS92379 was registered 0.5% plain insecticidal emulsifiable concentrate and Shanxi Province's Chinese herbal medicine agricultural chemicals head factory with LS95569,1.1% matrine pulvis of registration, respectively with a bitter bark, it is raw material that Chinese scholartree is really waited arbor, and there is lack of raw materials, and bigger to the forest destructiveness, product is difficult to the formation scale, this product insect protected face is narrow simultaneously, and contains industrial missible oil, contaminated environment.

The biopesticide that the purpose of this invention is to provide a kind of pure Chinese medicinal preparation.It has tag, stomach kills and strong osmosis, can infiltrate in plant tissue and the polypide, destroys insect pest cephalomere, body segment, makes insect spasm such as heart-eating worm on the crops such as fruit tree, vegetables, two spotted spider mite, aphid, star caterpillar, cabbage caterpillar, a red-spotted lizard shell class and dead.And people, animal are not injured environmentally safe.

The present invention relates to a kind of preparation method of broad spectrum pesticide of plant-biological pesticide.This insecticide is selected for use Chinese herbal medicine Chinese torreyanut, kuh-seng, hairyvein agrimony, the tuber of stemona, the root of langdu, alumen, the fruit of summer cypress to boil and formed, and its formula rate is: 20-35: 15-30: 12-25: 10-20: 10-15: 7-10: 5-10 also pulverizes (grinding).

This invented technology is simple, cost low, high efficiency, the saving of labor, save time, easily batch production production; The plant-biological pesticide insecticide of producing with this manufacture method is a kind of nuisanceless green wide spectrum agricultural chemicals; it has substituted chemical pesticide; reduced residual, protected environment; and desinsection is thorough rapidly, penetration is strong, lasting medicine, easy to use; people and animals are not had injury, are a kind of desirable biopesticides.

Attached one: the technological process of this plant-biological pesticide broad spectrum pesticide is as follows:

Annex II: embodiment

To produce one ton of product is example:

1, select materials: with Chinese torreyanut, kuh-seng, hairyvein agrimony, the tuber of stemona, the root of langdu, fruit of summer cypress dry product through impurity elimination soil, impurity elimination, rogue stand-by.

2, make up a prescription: 150 kilograms of 160 kilograms of 200 kilograms of 200 kilograms of Chinese torreyanuts, kuh-sengs, hairyvein agrimonies, the tubers of stemona, root of langdu 120 kg, the fruit of summer cypress got after selected fit over together for 70 kilograms.

3, pulverize: the Chinese herbal medicine Chinese torreyanut that will prepare in proportion, kuh-seng, hairyvein agrimony, the tuber of stemona, the root of langdu, the fruit of summer cypress mix pulverizes (fineness does not have strict demand).

4, grind: 100 kilograms of alumens are ground (the husky net of 60 orders).

5, tinning: divide 4 five equilibriums with Chinese herbal medicine that crushes and the alumen of grinding into powder, be respectively charged into 4 volumes that cleaned and be in the stainless cylinder of steel more than 500 kilograms.

6, Jia Shui: in installing four jars of medicine, inject 300 kg of water respectively.

7, vapour is endured: by opening the steam valve infusion 2 hours in the medicinal cupping that in the boiler steam pipe is fed injecting good water respectively.

8, cooling is soaked: steam valve is closed cooling soak every 2 hours with artificial or mechanical agitation once, soaked altogether 4 hours.

9, filter (preceding filter): open tapping valve, with 100 orders sand net with soaked medical filtration in sedimentation basin.

10, precipitation: the stoste of filtering is precipitated 2 hours in sedimentation basin.

11, refilter (back filter): will precipitate good stoste with 120 orders sand net filtration in concentration tank.

12, concentrate: under 80-100 ℃ of situation, be condensed into concentrate by the different proportion requirement.

13, preservative treatment: by per hundred jin of soups, get 1.0% water-soluble new azone and add in the soup.

14, homogeneous: with machinery and artificial the stirring half an hour.

15, canned: being contained in the can packing machine medicine liquid tank that homogeneous is good in 0.25 or 0.5 kilogram the plastics or vial, just is one ton of this product.

16, packing: go in the carton labeled product is bottled, 20 bottles in every case (10 kilograms) is put into the quality certification, joint sealing.

17, warehouse-in (treating pin): every batch of product is transported into warehouse for finished product with product after finishing technology, hands over administrator's warehouse-in of keeping accounts.
