Description
Technical field
The present invention relates to a kind of Pesticidal and sterilizing fumigant, especially a kind ofly control composite dose of the vikane that the worm sterilization kills mouse with fumigating method.
Background technology
Fumigant is stifling to be a kind of effective ways of control pest.Both at home and abroad import quarantines that insect pest processing, the building of control, food and job shop equipment and installation of all kinds of stored grain insects is stifling, heritage archive protection and soil-fumigating sterilization etc. adopt all that fumigant is stifling to be handled.But the situation that at present domestic and international fumigant faces is but very severe, the old kind of original fumigant, and all because of reason major parts such as hypertoxic, carcinogenic, inflammable and explosive, deep-etching, heavily contaminated, pesticide resistance have been eliminated, and new fumigant kind seldom appears on the market.
Now domestic also a large amount of use fumigant aluminum phosphate and Celfume are only arranged, aluminum phosphate is because inexpensive, (tablet pulvis) easy to use, its fumigant insect killing is almost all used in domestic silo, cigarette storehouse, but aluminum phosphate is by absorbing phosphine gas desinsection that water in air part decomposites, this is a kind of inflammable and explosive hypertoxic gas, exists bigger potential safety hazard, but also be corrosive, problem such as pesticide resistance and residue pollution; Celfume is a kind of good fumigant kind originally, but because it is the material that consumes atmospheric ozone layer, " Montreal Protocol Copenhagen amendment " stipulated its superseded process.
In the face of country very needs fumigant under the very short situation of real fumigant kind, vikane is is constantly researched and developed as the substitute of Celfume, yet though vikane itself has inhibitory action to fungi, invalid to bacterium, and the cost height, can't popularize on a large scale.
Summary of the invention
In order to solve the shortcoming and defect that above-mentioned prior art exists, the invention provides a kind of Pesticidal and sterilizing efficient height, environmental pollution is little and cost is low controls composite dose of the vikane that the worm sterilization kills mouse with fumigating method.
Technical scheme of the present invention: a kind ofly control composite dose of the vikane that the worm sterilization kills mouse with fumigating method, this composite dose composite the forming of assistant agent that is formed by one or more compatibilities in host vikane and oxirane, propylene oxide, chloropicrin, the Ethyl formate, the mass ratio of host and assistant agent is 1:0.5-2.Compatibility by host vikane and each analog assistant can overcome the defective that the former medicine of vikane is invalid to bacterium and cost is higher, makes composite dose of dual-use function and the synergistic effect with pesticide-germicide, and can reduce cost, and increases economic efficiency.
Preferably, described assistant agent is an oxirane, and the proportion compatibility of vikane and oxirane is 2:1.This kind compatibility mode makes composite dose in that to have under the dual-use function of pesticide-germicide an insecticidal effect better.
Preferably, described assistant agent is an oxirane, and the proportion compatibility of vikane and oxirane is 1:2.This kind compatibility mode makes composite dose in that to have under the dual-use function of pesticide-germicide a sterilization effect better.
Preferably, described composite dose also contains carbonic acid gas, and the mass ratio of host vikane and carbonic acid gas is 1:4-8.Add carbonic acid gas and can reduce composite dose production cost, but the pesticide-germicide performance significantly do not reduce, also increased the composite dose of efficacy of a drug permeability when stifling on the contrary.The carbonic acid gas consumption is during greater than four times of vikane consumptions, and its permeability is improved largely, and production cost also significantly reduces.
Preferably, this composite dose forms by vikane, oxirane and carbonic acid gas are composite, and the proportion compatibility of described vikane, oxirane, carbonic acid gas is 1:0.5:5.
Preferably, this composite dose forms by vikane, oxirane and carbonic acid gas are composite, and the proportion compatibility of described vikane, oxirane, carbonic acid gas is 1:2:5.
The present invention adopts one or more composite forming of host vikane and each analog assistant, has both solved the problem of existing insectofungicide Celfume environmental pollution, has also solved the defective that the former medicine of vikane is invalid to bacterium and cost is higher simultaneously.
