This insecticide is an insecticide that the inorganic or organic substrate containing a pyrethroid volatile at ordinary temperature is enclosed in the plastic film pouch which possesses many pores with a pore diameter of 0.02-2.0 mm&phiv all over the surface in a proportion of 0.005-0.3 as the ratio of the whole pore area to the film area.
Description
The present invention relates to contain the insect-proof agent of normal temperature volatility pyrethroid.
In order to remove the insect of living in the family, particularly the bag casemaking clothes moth, the curtain casemaking clothes moth, the black wool khapra beetle, dress material insects such as roundlet khapra beetle are being sold various insect-proof agents on the market.
These insect-proof agents were with paracide in the past, naphthalene, and sublimability insect-proof agents such as camphor are main, but at aspects such as insect protected effectiveness problem are arranged.In recent years, use the insect-proof agent of normal temperature volatility pyrethroid such as Prallethrin to popularize gradually.
For example, Prallethrin demonstrates than paracide for the dress material insect the active and anti-worm-eaten effect of higher insect protected, low dose is promptly very effective, but its shortcoming is for metal (especially copper compounds) is influential on every side, is easy to generate variable color and rotten problems such as (hereinafter referred to as " copper changes ").For this reason, for the insect-proof agent that contains this Prallethrin, from for reaching vermins-proof effect, the volatile quantity that is necessary and prevent that the viewpoint that copper becomes from setting out has proposed various schemes.
One of them puts into plastic casing with the insect protected tablet, can be described as the effective ways that prevent that copper from becoming, but the undeniable cost that improved.
In addition, also there are several schemes to propose with packings such as impregnation with agent body and function nonwoven.For example the spy opens clear 63-101301 communique proposition, is main component with the normal temperature volatile medicine, will contain the impregnation body of the medicament composition that keeps coloured or variable color in time, pays (Japanese basis weight) 35～70 gram/rice with order
2The Drug packing body of nonwoven packing of synthetic fibers system.This insect-proof agent is by the specific order amount of paying of nonwoven, also can prevent when guaranteeing volatile quantity because of the pollution due to the contact, but the copper that can't avoid causing because of Prallethrin becomes.In addition, open in fact flat 6-65402 communique and propose, in imbibition material, place the evaporant bag that graininess that a plurality of interpolations have mixed inorganic powder keeps impregnation evaporated liquor in the body, but this insect-proof agent can not solve because of the copper due to the Prallethrin and becomes problem.Contain normal temperature volatility pyrethroid like this, especially contain the insect-proof agent of Prallethrin, do not propose the motion that can solve all problems as yet.
The purpose of this invention is to provide can the temperature remains within the normal range the good insect protected activity of volatility pyrethroid, especially Prallethrin, and can worry to become insect-proof agent with brand-new function because of pollution and copper due to the contact of medicament.
In order to solve above-mentioned problem, the present inventor furthers investigate repeatedly, found that medicament carrier has been packaged in special pore size distribution and specific porose area ratio, and penetrating in the plastic film bag of many holes arranged, obtain the insect-proof agent that achieves the above object, thereby finished the present invention.
Promptly, the 1st invention of the present invention is the relevant inorganic or organic carrier that will contain the volatile pyrethroid of normal temperature, be packaged in the aperture is 0.02～2.0mm, and the hole is almost overall distribution, and it is insect-proof agent in 0.005～0.3 the plastic film bag that is installed with many holes that hole area/film size ratio is always arranged.
The used normal temperature volatility pyrethroid of the present invention can be enumerated chrysanthemum monocarboxylic acid 1-acetenyl-2-methyl-2-amylene ester (Prallethrin), 2,2-dimethyl-3-(2, the 2-dichloroethylene) cyclopropane-1-carboxylic acid 1-acetenyl-2-methyl-2-amylene ester (hereinafter referred to as " compd A "), 2,2,3,3-Tetramethylcycloprop-ne-ne carboxylic acid 1-acetenyl-2-methyl-2-amylene ester, 2,2-dimethyl-3-(2, the 2-dichloroethylene) cyclopropane-1-carboxylic acid 1-acetenyl-2-fluoro-2-amylene ester, 2,2,3,3-Tetramethylcycloprop-ne-ne carboxylic acid 5-propargyl-2-furans methyl esters (tetramethyl PH tefuramethrin), 2,2-dimethyl-3-(2, the 2-dichloroethylene) cyclopropane-1-carboxylic acid 2,3,5,6-phenyl tetrafluoride methyl esters (transfluthrin), 2,2-dimethyl-3-(2, the 2-dichloroethylene) cyclopropane-1-carboxylic acid 2,3,4,5,6-phenyl-pentafluoride methyl esters (fenfluthrin) etc.But be not limited to these.In addition, when optical isomer that produces owing to the asymmetric carbon atom in the chemical constitution or the geometric isomer due to two key existed, the independent or any mixture of isomer was also contained among the present invention certainly separately.In above-mentioned pyrethroid, render a service from insect protected, the aspect such as easily purchase, Prallethrin easily uses, but as alcohol moiety, has the pyrethroid of 1-acetenyl-2-amylene part, as previously mentioned, generally needs to consider prevent that copper from becoming.
Among the present invention except that the normal temperature volatility pyrethroid that adds as the insect protected composition, only otherwise diminish the invention characteristic, add allethrin, PH, other pyrethroid such as phenothrin if suitably cooperate, デ ィ-ト, insecticides such as repefral, pine camphor, linalool, citronellol, antibiotic property spices such as Eugenol, o-phenyl phenol, parachlorometaxylenol, 3-methyl-4-isopropyl-phenol, mould inhibitors such as allyl isothiocyanate, preventing microorganism agent and other deodorizer, aromatic, stabilizing agent, colouring agents etc. also can become multiduty insect-proof agent.
Among the present invention, as the inorganic or organic carrier of the temperature remains within the normal range volatility pyrethroid, can enumerate inorganic porous matter carrier (silicate, silica, zeolite, aluminium oxide etc.), paper, paper pulp, organic polymer carrier (cellulose, polyethylene, polypropylene, polyvinyl alcohol, ethylene-vinyl acetate copolymer etc.), gelation carrier (spiny dogfish dish glue, gelatin, alginic acid etc.), sublimability carrier (adamantane, the ring hendecane, norbornane etc.), above-mentioned one or two or more kinds the carrier of use also capable of being combined.Also can use graininess in addition, Powdered, drug sheet, bulk, formulation such as laminar.
