Description

Anti-mildew repellent pesticide and preparation method thereof

The invention belongs to the insecticide technical field, particularly, belong to a kind of anti-mildew repellent pesticide.

Books, archives insect are one of key factors of defective book, archives.These insects can make books, archives channel innumerable, lack the few page or leaf in limit, also can cause stained, adhesion of books, archives or the like simultaneously, punish severely the storage custody of defective book, archives, this class pest has kind more than 60, and primary pest has archives death watch beetle, lasioderma serricorne, Stegobium paniceum, Silvefish, coptotermes formosanus etc.Outside adding, mould also is one of key factor of defective book, archives, and it is a kind of microorganism, is grown on the nutrient matrix, forms fine hair shape, spider reticulation or cotton-shaped mycelial fungi.The books of grow mold, archives variable color.In addition, many moulds produce toxin in metabolic process, damage people's liver, kidney, and the direct damage people's who has brain and nervous system are that have even carcinogenic, the serious harm human health.And existing insecticide is not good especially for the insecticide insecticidal effect of books, archives, and also can work the mischief to staff and surrounding environment in production and use.

The object of the present invention is to provide a kind of collect desinsection, repellent, mildew-resistant be one, be easy to prepare, easy to use, to human body safety, novel sanitation Biocidal medicament free from environmental pollution, that materials such as books, archives paper, film, film are had no adverse effects.The preparation method of this insecticide is provided simultaneously.

In order to realize purpose of the present invention, the invention provides following technical scheme:

Anti-mildew repellent pesticide is the medicament of being made by following weight percentages:

Pyrethrins 10% eucalyptus oil 3% turpentine oil 5% menthol 2%

In the above-mentioned anti-mildew repellent pesticide, Chinese herbal medicine powder is preferably used rhizoma atractylodis, Jehol Ligusticum Rhizome, Ligusticum wallichii.

The present invention provides the method for preparing above-mentioned insecticide simultaneously:

A, get that rhizoma atractylodis, Jehol Ligusticum Rhizome, Ligusticum wallichii were pulverized by weight 1: 1: 1, mixing is standby;

B, get pyrethrins, eucalyptus oil, turpentine oil mixing, add menthol and camphor, add 5% sustained release agent shake well, add the Chinese herbal medicine mixing that the A step prepares at last;

C, get paraffin and put water-bath fusion, add residue diatomite and stir evenly, place and be cooled to 35-60 ℃;

D, B and C two parts are mixed, pour the model cooled and solidified while hot into and get final product.

Medicament of the present invention is a kind of natural compound insecticide, mainly by various plants with effects such as desinsection, repellent, mildew-resistant through processing, refining, rationally formulated.Insecticidal active ingredient is chrysanthemum ester class and part volatility terpene, have tag, repellent action, the anti-mildew repellent active component is aromaticity monoterpene and sesquiterpenoids composition, has strong repellent and mildew-proof function in various degree.

The main effect of each component and effect are in the prescription particularly:

Natural pyrethrin (containing six compounds): desinsection, mothproof, repellent.

Plants essential oil: eucalyptus oil-repellent, desinsection, anti-mildew.Turpentine oil-mothproof, repellent.

Diatomite: the sustained release agent of active component.

Paraffin: coagulating agent.

The action of contace poison of chrysanthemum ester constituents, main by contact intraepidermal fat of insect bodies and protein adsorption, the mixed-functional oxidase effect of insect is hindered, phenomenon is knocked down in generation, it invades blood by insect body wall or tracheae, stimulate each histiocytic nervous system of polypide and nerve fibre on every side thereof, benumb polypide fast and poison, last dead.Benezet, H.J. etc., the toxicity test of lasioderma serricorne Lasioderma serricome shows on corn flour-yeast or tobacco to raising to evaluate 11 kinds of insecticides by the drop processing in 1986: pyrethrins is stronger than cigarette alkali, dichlorvos, chlorophos etc. to the killing action of lasioderma serricorne.

The action of contace poison of part volatility ter penoids mainly enters polypide through respiratory system, and absorbing the back through tissue stimulates central nervous system that it is overexcited to cause polypide to shy Jue, tic, spasm and extremely, as turpentine oil, eucalyptus oil, Chinese prickly ash etc.

The anti-mildew repellent active component is plants essential oil and aromaticity Chinese herbal medicine.Wherein major part is monoterpene and sesquiterpenoids, as has menthol, Cineole, nopinene, rhizoma atractylodis, Jehol Ligusticum Rhizome of strong repellent action etc.Krishnarajah, S.R. etc., 1985 to certain plants oil and terpenes composition thereof to the primary pest gelechiid Sitotrgacerealella that stores rice avoid keeping away property and the toxicity test result shows: nopinene is the most effective repellant.Plants essential oil: eucalyptus oil, turpentine oil and aromaticity Chinese herbal medicine have all that contained geraniol composition has strong mildew-resistant and killing action to mould in various degree the antibacterial anti-mildew effect, particularly Chinese herbal medicine fine powder.

Below in conjunction with further specifying excellent beneficial effect of the present invention with embodiments of the invention, but content of the present invention is not limited thereto.

Detection through Yunnan Province health and epidemic prevention station, the biological effect test result of this insecticide is:

24 ℃ of temperature, humidity 80% time:

1, repellency test: examination worm: MonomoriumMayr, weevil, American cockroach

Result: the examination worm is had certain repellent action.

2, poison test: carry out according to GB13917.7-92

The result

The examination worm	Examination borer population (only)	24 hours lethality	48 hours lethality	72 hours lethality
					American cockroach	?????20	???30％	????90％	????100％
