    05 The invention relates to the manufacture of ear tags for animals that are capable of combating pest infestations. Animals, in particular. D7, domestic cattle (cattle, sheep, Senni, goats, horses) are often disturbing types of pests (facial, flies, lice, fleas, mosquitoes, mites) that are irritated by fi infection of the skin, eyes, and ears. This not only leads to disruption of normal feeding and grazing, but can also lead to serious illnesses and even chsepTU / KiiBOTHOio, because time-like 1 transfer is often transference and infection is a cyanotic disease. A test is used to manufacture yiuiiofi tags from a polymer material containing volatile insecticides, for example, 2,2-dichlor |: shnildsh.getil-fosyat (DVDF), which surrounds crayfish} The first part of the ear of an animal, 1) to prevent ticks that swarge out) The disadvantage of this method is that when using such a tape (ear tape), the protection is purely MecTHbrfi harasster, the protection period is two to three months, after which new tapes are to be attached to the animal's ears. . A known method for the manufacture of animal tags includes the preparation of a matrix from a mixture of thermoplastic SMOR-polyvinyl chlorine plasticizer dioctyl adipate and a stabilizer, dispersion in it of a insecticide and injection molding of a mixture z. The disadvantage of this method is that the tag contains insecticide / 3-chloro-1 (2, 4, 5-triclil prhenyl) -vinyl dimethyl phospliate, which is not sufficiently effective in the destruction of pests. IJej4b of the invention - enhancing the insecticide effect of the tag. The goal is achieved by the fact that according to the method, which includes the study of the matrix from a mixture of ter mollasisi resin — polyvinyl chloride, a plasticizer — dioctic adipate and a stabilizer, dispersing the insecticide in it in an insecticide molding the mixture, using an insecticide needle and using pytho – phenoxibs. 1-isopr (g or - h-chlorophenylacetate in the following ratio of components, wt.%: (X-Cyano-3-phenoxybenzyl-K-isopropyl-4 chlorophenyl acetate 8 Poly vinyl chloride 61 Dioctyl adipate. 28 Stabilizer 3 Manufactured by DINan animal tag is designed to be attached to the ear of an animal, at least part of the tag is made of a material that is represented; it is a polymer resin matrix in which at least one of the liquid insecticidal oC-cyo-3- isomer is dispersed phenoxybenzyl- (H.isopropyl-4-chlorophenylacetate. A tag can be made from the decree of the whole material. In the alternative, only part of the tag, for example, one component of a two-component tag can be made of the specified material. For convenience, the tag is completely made of the specified material. The proposed ear tags are of particular, but not exceptional, utility with respect to controlling pests, especially flies and ticks, in the area of cattle and other livestock, or on the animals themselves. The C-Cyano-3-phenoxybenzyl-about-isopropyl-4-chlorophenylacetate in this material contains at least 10% by weight of 3 - (-) - cx-cyano-3-phenoxybenzyl-S- (+) - (X-isopropyl- 4-chlorophenylacetate, In ear tags for animals obtained by the proposed method, the material consists of 35-75 wt.% Thermoplastic resin, 10-45 wt.% Plasticizer and 1–20 May.% (C-cyano-3 phenoxybenzyl X -isopropl-4-chlorophenyl acetate, os-cyano-3-phenoxybenzyl-о-о propyl-4-chlorophenylacetate is 3-15%, preferably 8-10% by weight of the material. If necessary, other ear tags can be added to the ear tags. Either add-on pesticides for enhancing or expanding (neither the spectrum of the activity of β-cyano-3-feioxybenzyl-o-iso propn.p-4-chloro-phylacetate, the polymer matrix, the resin in which the dispersed cs-cyano-3-phenoxy-benzyl is dispersed o-isopropyl-4-chlorophenyl acetate (hereinafter referred to as an insecticide), can be a thermoplastic or flexible thermosetting resin and an elastomer. It should be compatible with the insecticide and capable of releasing pesticidally effective amounts of the insecticide when the tag is attached to the ear of the animal to be treated. elastomers can be selected by matching the Gil solubility parameter, derbrand for the matrix material with a similar parameter for the insecticide. The solubility parameter for the insecticide was estimated to be approximately 8.3 cal 1/2 cm at 25 ° C based on the heat of evaporation and obtained from measured vapor pressure / temperature. The thermoplastic resins used include plasticized solid polyvinyl resins, in which the insecticide itself is one component of the plasticizer used. Such thermoplastic resins include polyvinyl halides, such as polyvinyl chloride (PVC), polyvinyl ethers, polyvinyl idenchloride, and chlorinated polyethylene. Plasticizers that can be used in combination with an insecticide to plasticize thermoplastic resins contain esters of polybasic acids: phthalic, sebacic, adipic and citric. Preferred plasticizers are dioctyl adipate and dioctyl phthalate. Plasticizer concentrations are 10-45 May.% Of the total composition, with 25-30 May being most desirable. The elastomers used include Brazilian hevea (hevea brasiliensis), c-is -1, -polyisoprene, polybuta diene and chlorinated natural and synthetic rubbers, thermoplastic elastomers, such as SBS (styrene-butadiene-styrene), SEPS (after roll-propylene -sti15nol), CEPS (hexane-ethylene-propylene-cyclohexane cycle) and CEVI (cyclohexane-ethylenebutylene-cyclohexane), in which the I 1t insecticide can perform the function of an oil for filling. As the flexible thermosetting resins, they can be used as ingredients for filling materials. dl coz after setting the solubility parameter of the insecticide after the mass has been cured to the desired shape. Examples of such resins are polyurethanes in which the bifunctional isocyanate (toluene-diisocyanate or diphenylmethane diisocyanate) is cured, for example, with a polyol, a polyol, KOTopbrii, a mixture, a solution, a set, and a solution, a space, a set, and a solution, a solution, a set, and a solution, a set can be used, a solution, a solution, a set, –– –– –– –– –– ––– ––– ––––––––) insecticide.In this case, the insecticide acts as an external plastic-fixer and gives flexibility to the device. Epoxy resins are also useful, for example, based on bisphenol A diglycidyl ether, where the curing agent is a long chain polyamine or long chain polybasic acid, and where the curing ingredients are specifically selected to act as an internal plasticizer to give the device additional flexibility. In order for the polymer resin material to be sufficiently strong and at the same time flexible, and also to have low CTotTMocTb, plasticized thermoplastic resins are used, in particular polyvinyl chloride, plasticized with dioctyl adipate or dioctyl phthalate. As a rule, the flexible polymer resin used in the ear tags is 35-75% by weight of the total composition, preferably 40-70% by weight. In the proposed ear tags, it is possible to use other ingredients: stabilizers, attractants, dyes, fillers, coloring agents or other biocides. For coloring the polymer matrix, additives such as carbon black, titanium dioxide and other insoluble pigments and fillers can be used, which are added in small amounts (1 wt.% Or less). For example, o-cyano-3-phenoxybenzyl, α-isopropyl-4-chlorophenylacetate may be dry blended with a thermoplastic resin and plasticizer and then mixed to form a homogeneous melt that is directly used for pressure casting. Alternatively, cyano 3-phenox 1-benzyl-oi-isopropyl-4 chlorofennl-ketar can be dispersed in 1% of the mixtures of the thermosetting composition, which is then formulated and retained. Ushna tag may have different forms. For example, it can be made as a single element or ribbon, one end of which can be used to pierce the ear of an animal. In the alternative, a two-element fastening system may be used, based on the use of screws, pins or pins. The liquid insecticide-active isomers of oi-cyano 3-phenoxy benzllI-i .-- isopropyl-4-chlorophenylacetate have a high level of insecticide, activity, and the animal that wears an ear tag according to the invention is free from flies and other jellyfish, and also the animal wearing nose ear tag is free from flies and other jellyfish, and also the animal that wears the ear tag of the invention is free from flies and other jelly fish, and also the animal that wears the ear tag of the invention is free from flies and other jelly fish. ticks, over a period before the snake, or more. The efficacy of the ear tag is related to the insecticide migraine from the ear tag to its surface and from there to the skin of the animal, the latter migration being associated with the natural dvgokeniyu of the animal and its ear. A significant positive effect of the invention is that the use of ear tags is necessarily identification targets and is an established practice. In this case, the proposed ear tag can be identical in shape and appearance with a well-known, but in addition it is able to maintain the tag-bearing animal in a state that is substantially free from flies. Example 1. Ear tags containing, in wt%, oi-ciaio-3-ebluexy benzyl o6-isopropyl-4-chlorophenylacetate insecticide, 8 (about 23% of which are stereoisomer (-) - 5-cyano) -3-phenoxybeisyl (+) 3o-isopropyl-4-chlorofenster acetate); Dio-tiladipate-plasticizer-28; ITBX 61 and stabilizer for PVC 3.0 are prepared by mixing liquid ingredients (insecticide, plasticizer and stabilizer) with powder, PVC, and heating the resultant mixture to obtain a dry free flowing powder (dry mixture). the mixture is fed into the hopper of the injection molding machine 5 where it is heated, to withstand melt, mixed until homogenized. and forced into matrix cavities having confines. Gurazgao ear tags, after which the matrix is cooled with the receipt of tags. PREMIER- 2, Obtained in example 1, ear tags are used to determine their effectiveness in the fight against face flies and cow flies, in small cattle, Upscale tags are attached to ears of goby herds for 25 heads. After that, the farm is placed on a 20-acre square of grazing for six weeks and then transferred to a 40-acre area of pasture for the rest of the period. A week before tags are attached and the number of flies and flies is calculated weekly in one day at ten arbitrariness, selected ANIMALS TX. The control is a herd of 19 gobies; i those ,, OK5 which are located near the marked animals. The results obtained during these examiners are presented in Table. 1 and 2, Efficiency in relation to gigal-alo-to bovine small cattle is given in Table 1, 1, where the number of flies, percentage of st-shephee and weeks after treatment are given. Efficiency in relation to facial flies on cattle is given in tab. 2, where the number of flies is indicated, and the percentage of decrease and weeks after treatment, EXAMPLE 3. Ear tags, similar to those used. in example 2, it is used to determine their effectiveness in relation to ixodic ticks of the western and w-needles of bovine small ones. A herd of 31 mixed breed cows into two groups., Of 15 and 16 animals corresponding to "Animal" from a group of 15 cows are attached to: each one with the right tag, whereas. A group of 16 animals. Pets are made and it serves as a control. The number of ticks located on the ears of animals is counted on the treated and untreated animals with time. at the intervals indicated in the table. 3. And the same animals spend. Counting the zhiga.pok when processing in the described way. Specified in the table. four
    71
    the number is a complete estimate for the carcass. .
    The untreated, with which the above herd was compared, consisted of 16 cows and 11 cross-delusional bodies in the next room.
    The effectiveness against small bovines is presented in table. four.
    Example 4. Stability with l-points of evaporative loss for insecticide-containing plasticized PVC materials, which are used to make ear tags according to examples 1-3, are determined by placing the 0.1-inch thick molded under pressure. mm) from the proposed composition to the furnace at a temperature of 130 ° C (54,) for different time intervals, after which the plates are analyzed for the content of the insecticide (cyano-3-phenoxybenzyl-c-isopropyl-4-chlorophenylacetate) and the plasticizer (disk, tiladipate ), and Performan presented in Table. five.
    eleven . eight
    The figures show that neither the insecticide nor the plasticizer is lost in any significant amounts during the prolonged exposure to a temperature of 130 ° C (54.5 s), which is significantly higher than the normal temperature of the cows or other livestock. From the above data it is obvious that the unexpectedly high efficiency of the proposed ear tags is not related and not predictable in terms of the evaporative characteristics of the material from which the ear tags according to the invention are made.
    Example 5. Molded. casting under pressure shchastinki 0.1 inches thick; (2, -54 mm), from which make the proposed ear tags, by. Example 1, is stored in a plastic bag for 11 months, after which the surfaces are examined under a microscope using polarized incident light at 120x magnification. No evidence of crystallinity of the insecticide on the surface was detected. Composition. I. Table 1
