Description

0.36% aqueous matrine solution

The invention belongs to a vegetative insecticide.

Though agricultural chemicals is to guarantee that agricultural is stable, the key factor of high yield, but the present chemical pesticide that uses, not only the environment to human living has caused severe contamination, and grain, vegetables, fruit and other edible economic crops of using chemical pesticide are caused severe contamination.Chemical pesticide pollutes has become global public hazards.According to incompletely statistics, at present the chemical pesticide kind reached hundreds of more than, annual sales amount has broken through 30,000,000,000 dollars, on average everyone uses volume to surpass 5 dollars, the annual whole world has surpassed 4,000,000 people because of the pesticide poisoning number that causes death.The production of China's chemical pesticide and use are also increasing rapidly, and pesticide species has reached kind more than 120, and annual production is at the beginning of liberation more than 130 times, and the tremendous development that promotes China's agricultural production has been played important function.Yet also bring serious pollution effect.1/7th of China's arable area by pesticide pollution according to the statistics made by the departments concerned, and this pollution comprises the pollution to atmosphere, soil, water quality and crop, and the health of human body has been caused infringement in various degree.Solve the chemical contamination problem, become very urgent task.

Purpose of the present invention is to provide a kind of to environment, the free of contamination 0.36% aqueous matrine solution agricultural chemicals of crop at the problems referred to above.

Purpose of the present invention realizes by following technical proposals, that is:

0.36% aqueous matrine solution is mixed with by vegetable insecticide and anticorrosion synergist.The weight ratio of vegetable insecticide and anticorrosion synergist is 1: 1.Vegetable insecticide is risen by pure natural plant kuh-seng, tobacco, the tuber of stemona, chinaberry, Dalmatian chrysanthemum, catharanthus roseus, Thunder God and is mixed with, and its compatibility is: kuh-seng 40%, tobacco 20%, the tuber of stemona 10%, chinaberry 15%, Dalmatian chrysanthemum 5%, catharanthus roseus 4%, Thunder God rise 6%.Anticorrosion synergist is mixed with by turpentine oil, ethanol, emulsifier, bleeding agent, preservative, and its charge ratio is: turpentine oil 29%, ethanol 44%, emulsifier 18%, bleeding agent 8%, preservative 1%.Above-mentioned percentage is weight percentage.Emulsifier can be that tween 30-60, bleeding agent can be dimethyl sulfoxide (DMSO), preservative can be Sodium Benzoate.

The production method of 0.36% aqueous matrine solution:

By the charge ratio requirement, get kuh-seng respectively, tobacco, the tuber of stemona, chinaberry, Dalmatian chrysanthemum, catharanthus roseus, Thunder God is risen, and pulverize respectively, soaked 6 hours down at 30 ℃, it is interior after 90 ℃ of following boilings are extracted 6 hours to be put into extractor then, filter, be decompressed to-0.5～-1 in the triple effect inspissator, concentrate down at 70～90 ℃, each concentrate of gained is put into reactor to be mixed, put into the settling tank precipitation again, filter,, send into to return in the reflux column and heat up in a steamer gained filtrate, collect mother liquor, the mother liquor of collecting is put into reactor, add turpentine oil successively by charge ratio again, ethanol, emulsifier, bleeding agent and preservative reacted 2 hours, be the aqueous matrine solution finished product, matrine content is 0.36%.

The matrine empirical formula:

C ₁₅H ₂₄N ₂O。

The physicochemical property of aqueous matrine solution of the present invention.

The effective content of matrine in soup is 0.36%.

Outward appearance: the dark brown homogeneous liquid, do not have visible suspension.

Density: 995kg/m ³

Acidity: with H ₂SO ₄Meter＜1.0%.

Stability of emulsion (extension rate): 800,1000,1200.

Storage at normal temperature stability: store under shady and cool lucifuge condition, the shelf-life is 2 years.

With other agricultural chemicals mixcibility mutually: to use preventive effect with better with chrysanthemum lipid and acid agrichemical.

The insecticidal mechanism of 0.36% aqueous matrine solution:

The Main Ingredients and Appearance of Chinese medicine kuh-seng is matrine (C ₁₅H ₂₄N ₂O) good insecticidal action is arranged.When medicine contacts with polypide, can pass to central nervous system through peripheral nerve by the epidermis internal layer that penetrates to the skin, make polypide produce overwrought poisoning symptom, cause at last being choked to death.Mainly to tag, the stomach of also holding concurrently kills effect.

0.36% aqueous matrine solution agricultural chemicals, through in Beijing, ground such as Tianjin, Henan, Hunan, Liaoning, Hebei, Zhejiang, Fujian, Shandong have following characteristic and advantage to the test of pesticide effectiveness proof in farmland, gardens:

1, has efficient, broad spectrum activity

This agricultural chemicals is applicable to the Lepidoptera of vegetables, fruit tree, flowers, forest, field crop, Semiptera, sticks up the control of 40 various pests such as wing order, Homoptera and diptera, its efficient 85-98% that reaches.

2, hypotoxicity

0.36% aqueous matrine solution not only insecticidal properties is good, and low toxicity.Through entrusting the Ministry of Chemical Industry's chemistry security to estimate " toxicological test of 0.36 aqueous matrine solution " that the supervision and inspection center is done, regard as low toxicity.It is a kind of novel plant aqueous pesticide.

3, has the noresidue characteristic

General chemical pesticide is also had residual (being residual hazard) problem of toxicity except that the higher toxicity of tool, and residual life is long, and damaging range is wide, even can precipitate in human body, animal body and accumulate and cause serious harm.For example, scientist competes to have found the molecule of hexachlorcyclohexane in the penguin body that this piece of the South Pole is not lived by large-scale development, and how extensive and serious the pollution of visible chemical pesticide is.0.36% plant pesticide is natral plant ingredients sheerly, and there is not the toxic residue problem in the low toxicity product through science processes with the application proof after testing, thereby also can be to humans and animals and ecological formation harm.

4, has the nothing of production " three wastes " characteristic

" three wastes " are the important sources of environmental pollution, also are the objects that manufacturing enterprise should pay attention to administering.But the present invention facts have proved by development and production, does not have " three wastes " problem.(1) remaining waste residue in the production can fully utilize " turning waste into wealth ".Promptly useless dregs of a decoction fermentation makes it to produce biogas, as good using energy source.The dregs of a decoction after the fermentation can be prepared serial high-quality composite fertilizer, as having made " genseng fertilizer ", " grape fertilizer ", " fruit and vegetable fertilizer " etc., good future and wide market are arranged.(2) industrial water after the use can be recycled after simple process again, can utilize winter full thermal cycle to do heating and use.(3) nonpollution environment waste gas.
