The preparation according to the invention has a lower corrosion activity and good stability. 3 table. The invention relates to a means of combating harmful insects, namely, to insecticide products based on pyrethroids.It is known that a PYRETHROID insecticide of low mammalian toxicity widely used in spray household insecticide products.Known portovoi solvent (KBO. INF. The means of control of household insect repellents, raticide, dedamiwa drugs. - M, Niitekhim, 1978, S. 41).A disadvantage of the known tool is the low efficiency and low residual insecticidal activity.The closest to the invention is an insecticidal product containing permethrin, tetramethrin, synergist of piperonylbutoxide, solvent and hydrocarbon propellant (Patent USSR N 1466635, a 01 N 53/00, 1989).The disadvantage of this drug is that when high efficiency of its toxicity is low enough due to the high concentration of poisons-pyrethroids factor of 1.5 to 40 wt.%. The composition also has corrosion resistance, which affects the lifetime of aerosol cans.In addition, it is possible incomplete dissolution of poisons in the solvent, which leads to their poor respisense, reduced activity of the drug and to clogging of the valve of the aerosol container.The technical result achieved with the invention is increased insecticidal activity while decreasing the toxicity of the drug while reducing its corrosion activity, and improved RA containing permethrin, tetramethrin, piperonylbutoxide, solvent and hydrocarbon propellant, contains cypermethrin, diethanolamide fatty acids and dimethyl sulfoxide, and the solvent it contains hydrocarbon or alcohol solvent in the following ratio, wt.%:
Cypermethrin is 0.01 to 0.70
Permethrin - 0,05-1,0
Tetramethrin is 0.01 to 1.2
Diethanolamide fatty acids - 0,01-0,5
Piperonylbutoxide - 0,1-20

In insecticide preparation according to the invention, as active substances (ADV) used pyrethroids - cypermethrin, permethrin and tetramethrin. As a synergist amplifier action ADV - used piperonylbutoxide and diethanolamide fatty acids, the latter is also a corrosion inhibitor. Dimethyl sulfoxide enhances the action ADV by improving their penetration through the chitinous integument of insects, and also contributes to a more complete dissolution ADV mainly hydrocarbon or alcohol solvent.Using diethanolamine fatty acids and dimethyl sulfoxide for Tipam, that significantly reduces the toxicity of the drug. At the same time decreases the corrosion activity of the drug.Insecticidal preparation is prepared as follows.In the reactor, pre-tested for purity and treated with an inert gas, load the estimated amount of the solvent is a synthetic ethyl alcohol or kerosene, or nefras. Weighed and loaded into the reactor, the estimated number of piperonylbutoxide, then tetramethrin. Include the stirrer. The mixture is heated to 30 - 40oC and stirred for 30 to 60 minutes until complete dissolution of tetramethrin. Then pump into the reactor cypermethrin and permethrin, preheated to 40 - 42oC, and stirred for 15 to 20 minutes. Then download the sulfoxide and again stirred for 5 to 10 minutes until complete dissolution of the components.Latest download diethanolamide fatty acid, stirred for 15 - 20 minutes, then turn off the mixer and select the sample for analysis to verify the quality of the finished product.Table 1 shows examples of formulations of the drug.The stability of the resulting preparation was examined to determine the shelf life and expiry date on the basis of henia original values of the content of active substances (ADV), founded in the recipe (THE project) was placed in a thermostat and kept at a temperature of 40oC for 5 months, which corresponds to the storage at a temperature of 20oC for 18 months. The stability of the preparation was checked during the whole period of "accelerated aging" with a periodicity corresponding to 3, 6, 9, 12, 15 and 18 months of storage at a temperature of 20oC.Table 2 shows the dynamics of the content of ADV in insecticide drug during storage, determined by gas chromatography.Table 2 shows that the active substances within 18 months of almost not lose activity. Comparing examples a and B, you can see that the introduction of a composition consisting of three ADV-cypermethrin, permethrin and tetramethrin - diethanolamide provides the claimed composition due to the discovery of new synergies significant sharply improved properties, namely, increased insecticidal activity and increased chemical stability of the drug. At the same time, the variation of the components in the claimed limits, you can adjust the nature of the activity, i.e. depending on its destination, you can increase or residual action, or acute, not reduce the To determine the insecticidal activity experiments were set on the fly (Musca domestica), mosquitoes (Cuiex pipiens pallens) and red cockroaches (Beattella germanica).Acute insecticidal activity of the drug was determined in the cell volume of 2.0 m3when the temperature and relative humidity of the air in the room 20 - 25oC and 60 to 70%, respectively. Each concentration of the drug experience in triplicate.To determine the acute effect against flies and mosquitoes camera were treated with aerosol insecticidal composition corresponding to the composition and the consumption of the drug is 1 mg per 1 m3premises, directing a jet of aerosol and witnessed the destruction of insects, specifying the time within which kills 99% of insects. Then the expected value of C15 - concentration that causes death in 99% of insects in 15 minutes.The analysis of table 3 shows high acute insecticide action claimed the drug.The duration of the residual effect of the drug was determined on test surfaces that were treated with the drug and kept within a certain period of time. To do this, as the test surfaces used plate glass, which was treated by drug aerosol from the calc is within 5 and 15 minutes. Each experiment was performed at least four times using not less than 30 insects. The contacts were in the first week every day, and then at intervals of 2 to 3 days. The criterion for assessing the validity of the drug served as insects, expressed as a percentage. For the final result took the average of three parallel definitions, allowable differences between them does not exceed 10%.The results of the experiments for conducting acute and residual effect are given in table. 3. The camera was placed at least 100 flies and mosquitoes or cockroaches, respectively.To determine the acute effect in respect of houseflies treated the camera aerosol preparation of the composition. When the consumption of the drug is 1 mg per 1 m3premises, directing a jet of aerosol in the air. The chamber was closed and witnessed the destruction of flies, determining the time during which kills 99% of the flies. Then, the counted value C is the concentration that causes death 99% of the flies in 15 minutes.
