Abstract

The preparation method of a Chinese medicine preparation biological pesticide "Zhibao 102" with broad spectrum is characterized by that said pure Chinese medicine pesticide is made up by using 7 Chinese medicinal materials of torreya nut, flavescent sophora root, agrimony, stemona root, Chinese wolfsband root, calcined alum and kochia fruit through the processes of selecting material, pulverizing (grinding), decoding, filtering, precipitating, secondary filtering, concentrating and preservation treatment. Said pesticide possesses the obvious control effect for controlling insect pests of core-eating insect, red mite, scale louse and cabbageworm, etc. It has no environmental pollution, and is harmless for human body and animals.

Description

The preparation method of plant-biological pesticide broad spectrum pesticide " plant protection 102 "

The present invention relates to the preparation method of a kind of nuisanceless green environment protection biological agricultural chemicals broad spectrum pesticide " plant protection 102 ".

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, be raw material with arbors such as a bitter bark, Chinese scholartree fruits respectively, there is lack of raw materials, and bigger to the forest destructiveness, product is difficult to row on a large scale, and this product insect protected face is narrow simultaneously, and contain 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 to people, animal do not injure, environmentally safe.

The present invention relates to a kind of preparation method of broad spectrum pesticide of plant-biological pesticide.This insecticide " plant protection 102 " 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 into powder).

The technological process of this plant-biological pesticide broad spectrum pesticide is as follows:

Select materials

|

Make up a prescription

|

Pulverize (fineness does not have strict demand)

|

Grind (fineness is the husky nets of 60 orders) into powder

|

Tinning

|

Add water (1200 kilograms in the water that adds per ton)

|

Vapour is endured (100 ℃ of vapour were endured 2 hours)

|

(soaking 4 hours fluid temperature falls in the cooling immersion

| to below 35 ℃)

Filter (the husky net of 100 orders)

|

Precipitation (2 hours)

|

Refilter (the husky net of 120 orders)

|

Concentrate (concentrating) by difference requirement concentration

|

The synergy preservative treatment (is mixed 1.0% water-soluble new azone

| and 2.5% food antiseptics)

Homogeneous (with machinery or manually stir evenly)

|

Filling and sealing

|

Labeling

|

Packing

|

Warehouse-in (treating pin)

This invented technology is simple, cost is low, high efficiency, the saving of labor, save time, easily batch production production; The plant-biological pesticide insecticide of producing with this manufacture method " plant protection 102 " 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.

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 into powder: 100 kilograms of alumens are ground into powder (the husky net of 60 orders).

5, tinning: divide 4 equal portions 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.
