Description

Compound chinaberry-Radix Sophorae Flavescentis pesticide for animal and plant protection

Patent name of the present invention is a compound chinaberry-Radix Sophorae Flavescentis pesticide for animal and plant protection.

Patent of the present invention relates to a kind of botanical pesticide that is novel, wide spectrum, nontoxic, noresidue.

At present, known various agricultural chemicals major parts are chemical pesticide, have toxicity more, contaminated environment, and can be residual in animals and plants, the health of harm humans.Simultaneously, damage by disease and insect is developed immunity to drugs.Develop the highly effective pesticide of a kind of nontoxic, wide spectrum, noresidue, then be a global problem always.

Patent of the present invention is finished by exploitation motherland medical treasure-house.The compound China tree kuh-seng plant protection insecticide that it provided then is the great revolution that the traditional chemical agricultural chemicals is done.Compound chinaberry-Radix Sophorae Flavescentis pesticide for animal and plant protection is a brand-new product, and at present, the farmland of China reaches 1,500,000,000 mu.Count in together with multiple cropping area and plant area, then more surprising, annual agricultural chemicals requirement is more than 500,000 tons, and market is very wide.External agricultural chemicals market is then more wide.Along with human culture level and growth in the living standard, more and more clear to the understanding of residue of pesticide in the crop, it is also more and more urgent to settle the matter once and for all.Yet since what years, thoroughly solve in the animals and plants crop residue of pesticide is a hard nut to crack always.Because chemical pesticide is easy to make damage by disease and insect to develop immunity to drugs, so people have to strengthen the dosage of use, so that in the animals and plants crop, agricultural chemicals residual more and more serious directly threatening human healthyly, destroying the environment around ours.And this product is undoubtedly a big Gospel for wide farmers so that for the whole mankind.Its market will be very wide.This fauna and flora protection insecticide can also be developed and be exclusively used in the product of eliminating the mosquitos and flies class in public arena, city, refuse depot and the family and the product that is exclusively used in aquaculture (killing the insect in river embankment, stream, lake and the sewer water), livestock culturing aspect.In addition, at vegetables, these need the material object and the grain of immediate access fruit, tobacco, trees, the grassland, the needs of non-immediate access such as rubbish heap, can produce different products discriminatively, to develop market, plug a gap (China does not still have the medicine that is exclusively used in rubbish at present) extensively act on the ground vegetables, fruit tree, tobacco, cereal crops, tealeaves, the thorn Siphonata of flowers and forest etc., Aristotle's lantern class damage by disease and insect such as aphid, cabbage caterpillar, cotton sandfly worm, the cicada class, the flea class, lice class etc., simultaneously, to underground all kinds of damage by disease and insect also have a very strong killing action, have wide spectrum, efficiently, nontoxic, noresidue, characteristics such as be difficult for developing immunity to drugs.The effect that volume increase, diseases prevention are also arranged simultaneously.

The purpose of patent compound chinaberry-Radix Sophorae Flavescentis pesticide for animal and plant protection of the present invention is achieved in that common chinaberry; kuh-seng; the tuber of stemona; tobacco leaf; garlic; Dalmatian chrysanthemum; subprostrate sophora (asiatic moonseed rhizome); the root of large-flowered skullcap; isatis root; the fruit of Rangoon creeper; melia; Lappula echinata; fructus ulmi; betel nut; stone-like omphalia; rhizome of cyrtomium; pomegranate root skin; Chinese torreyanut; Chinese herbal medicines such as pumpkin seeds (siccative or wet feed); according to chinaberry; kuh-seng; the tuber of stemona; tobacco leaf is main; garlic; Dalmatian chrysanthemum; the fruit of Rangoon creeper; melia; Lappula echinata; fructus ulmi; betel nut; stone-like omphalia; rhizome of cyrtomium; pomegranate root skin; Chinese torreyanut; pumpkin seeds are the formulation principle of assisting; get by decocting essence respectively; ways such as methanol extraction; extract its effective ingredient, separate exchange then and form.Under normal conditions, chinaberry accounts for 10 parts, and kuh-seng accounts for 30 parts, and the tuber of stemona accounts for 5 parts, and tobacco leaf accounts for 30 parts, and garlic accounts for 5 parts, and Dalmatian chrysanthemum accounts for 5 parts, and other account for 15 parts proportional arrangement.In order to prevent to go mouldy, can also suitably add the non-toxic anticorrosion agent of trace.

The tuber of stemona is the plant that belongs to the Stemonaceae Stemona, subterraneous root piece for Stemonaceae herbaceos perennial Radix stemonae japonicae and radix stemonae sessilifoliae, majority clusters, and meat is done spindle usually, dry product is about 2---and 4 cun, thick 2-3 branch, two ends are narrow thin, the yellowish-white or lark of appearance, shrinkage is dark, shows irregular dark longitudinal furrow; Matter is pliable and tough, section yellow-white, band meat, the sweet and little hardship of distinguishing the flavor of, China all produces in most of area, mainly is distributed in provinces such as Shaanxi, Shandong, Anhui, Jiangsu, Fujian, Jiangxi, Hunan, Sichuan, the digging in autumn, go into boiling water after cleaning and scald a moment, promptly got to deliquescing, segment is used as medicine.Its nature and flavor are sweet, bitter, and tepor has the delousing disinsection efficiency, can kill insect and all the trees moths of crops, also can kill lice and fly midge.The composition of the tuber of stemona is an alkaloid, it is documented nine kinds more than, and stemonine STEMONINE is wherein arranged, and is prismatic crystallization, fusing point 151 degree, and specific rotation is-113,8.Stenine PAIPUNINE, fusing point 105,5-106,5 degree.The extraction method of tuber of stemona effective ingredient is as follows:

Kuh-seng is the root of the perennial undershrub kuh-seng of pulse family, and dry root is grey black, and is sturdy and grow, and skin is rough significant vertical wrinkle, becomes channel form; The hole skin projection of growing crosswise, matter is hard.Kuh-seng is distributed in all parts of the country, and spring and autumn is adopted, dry, and the nature and flavor hardship, cold, go into liver, small intestine, large intestine, stomach warp, have removing damp-heat, wind dispelling insecticide, the effect of Li Shui is usually used in wind dispelling insecticide, sore scabies etc.

Matrine (MATRINE) extracts from radix sophorae, and it is about 2% to contain matrine, is column or acicular crystal, and fusing point 75-77 degree all can dissolve in cold water, alcohol, chloroform, ether, benzene, be slightly soluble in benzinum, but hot water is littler than cold water solubility.Under heating, can be dissolved in the dense potassium hydroxide.Extraction method is: get radix sophorae and chop up, with ethanol hot dipping 2-3 time, merge alcohol extracting and follow the example of, after the evaporation and concentration, add suitable quantity of water and hydrochloric acid and make acidity, remove by filter resin.Acid filtrate extracts for several times with moving the ether jolting, removes foreign pigment, and water layer use chloroform extraction after adding ammoniacal liquor or potash alkalization, after carrying most alkaloid, combined chloroform liquid, the recovery chloroform and be evaporated to dried, again with extracted by ether.The ether extract promptly gets matrine after reclaiming ether.Also kuh-seng can be pressed into fragment, add 0,5% salt sour water about three times, soak and use filtered through gauze after one hour.So repeatedly for several times, concentrate cooling then, the alcohol that adds three times stirs, and filters the back and reclaims ethanol, transfers to pH value more than 8 with sodium carbonate liquid, adds equal amounts of chloroform and is extracted into stoste inanimate object alkali reaction, reclaims chloroform, adds water, transfers to pH value about 6 with watery hydrochloric acid.

Active principle in the chinaberry is a toosendanin.The extraction of toosendanin can be adopted wet carbon adsorption, with chinaberry or amargosa chopping, leaches for several times each about one hour with hot water thermal insulating.The consumption of hot water is three to five times of spice.After merging leachate for several times and being cooled to 50 ℃, with the flow velocity of 300 to 500 milliliters of per minutes, by wet charcoal absorption (wet charcoal consumption be raw material once measure about 1/2nd to 2/3rds, can use repeatedly).Get charcoal end after the absorption with the hot water wash decontamination, use 70% ethanol at 50 ℃ of flush away toosendanins then, consumption of ethanol is about three times of raw material, and flow velocity is per hour about 12 liters.Then ethanol is reclaimed in the ethanol eluate decompression distillation, the residue drying is got.

The extracting method of other batchings slightly.

Above-mentioned spice is prepared after extracting respectively, and the concentration of working good is about about 0,5% to 5%.During use, according to the prevention and the different needs of desinsection, spray after dilute 300 times to 400O times, its effective killing rate is more than 90 percent.
