CS200602B1 - Bait for the destruction of small rodents - Google Patents

Description

The subject of the invention is a bait composition for controlling small rodents, small rodent control, Mus musculus, Field mouse Apodermus agrarius, Field Vole Microtus arvalis, Ground Vole Microtus egrestis, etc. only a small amount of rodenticidal agents are currently available in field and wildlife, the effectiveness of which is reduced by the low attractiveness of the used bait forms, the instability of the rodenticidal effect of the toxic substance itself, and the riskiness of these preparations for domestic, farm and wild animals. The rhodonticides and baits used so far are listed in the List of Authorized Plant Protection Products 1975, issued by the Federal Ministry of Agriculture and Food in March 1975 and in the company literature. These baits in the form of dusts, nobo loose or liquid mixtures are the most commonly used form. Solid baits are produced only sporadically, based on the formation of a mixture of cereal or scrap, or flour with hardeners, which contain mainly only solid paraffin, nobo only beef tallow, or food fat. For example, a preparation made by us containing oatmeal, sunflower or similar oil, beef tallow, starch or gelatin hardener, dye and phosphide are zinc formed into granules. Or, for example, an imported preparation containing coarsely ground maize, a dye, Warfarin as a solid paraffin binder. Currently, the main form of rodent control and rodenticide baits is a mixture of cereal with its own rodenticide and some

200 602 orchards, eventually it is used directly cereelii seaweed (impregnated) with the active substance. In the first case, loose or. semi-loose mixture, which after nastrožoni Jo in a short time lumbered and devalued animals. so that its efficacy is significantly reduced within a few days. Considering the economic question, it is evident that cereals, scrap and vegetable oil are used to prepare baits of this kind. These are the tints of euro coins that are farmed nationwide. A further point in the unsuitability of such baits is that the baits thus prepared are laid in a quantity which far exceeds the real need corresponding to the procedure being performed. One lure of this nature is 150 to 500 g of bait containing about 90% of cereals or scrap; for example in a farm, these baits are laid in a total volume of 250 kg, even more. Also, baits of this kind are not controllable in a short time after being set up, they are devalued and are not reusable, making the methods of rodent control conducted in this way generally ineffective. The use of grains impregnated with a rodentide is similarly assessed for similar reasons. Deko perspective is generally considered to be those bait compositions that are manufactured, distributed and applied in solid form while achieving rodent attraction, environmental resistance, and health and safety in production, distribution and application.

The above drawbacks are further reduced by the rodent control composition of the present invention. It consists of 6.25 to 33.25% by weight of greaves, 2.75 to 29.75% by weight of cereal scrap, 3 to 8% by weight of cereal, 5 to 27.75% by weight of wood sawdust, 1 to 1% by weight of sugar, 0.1 to 0.25% by weight of a preservative, for example p-nitrophenol, dinitro-o-krezoz, organotin compounds, 7 to 9% by weight solid paraffin, 25 to 36% by weight fat, for example melted tallow , hardened shortening, confectionary fat, edible, camphoric fat, 0.001 to 0.002% by weight of a fat-soluble organic dye, e.g. anticoagulant rodentide derivatives, zinc foefide, chloro-dimethylamino-methyl-pyrimidine, eclolroeld.

A preferred solution is a non-baiting composition comprising 2.5 to 2.8 weight percent alpha-chloroelea. When coumarin anticoagulant rodentide derivatives are used, these are dosed in amounts of 0.25 to 1.5 wt. percent active ingredient. When using cumachlor, it is dosed in an amount of 0.25 to 1.5 wt. percent active ingredient. When using zinc phosphide, this is dosed in an amount of 2 to 10 wt. % of the active ingredient, when using chloro-dimethyl-amino-methyl-pyrimidine, it is dosed in an amount of 0.5 to 10 wt. percent active ingredient. When scilliroside is used, it is dosed in an amount of 0.25 to 10% by weight of the active ingredient. When using the active ingredient alpha-chloraloeye, this non-bait composition is sought after by small rodents, preferably consumed, and due to the rapid absorption of the active substance from the fat-related nutrients, a manifestation of an appropriate rodonticidal effect occurs shortly after use of the bait.

The bait prepared in this way is permanent in compact form, it can be stored for a long time under normal conditions of storage and is also resistant in the environment! High humidity. At the place of laying or boiling it is long-term resistant to environmental influences, while maintaining efficiency. The prepared bait is firm, formed, well and safely storable, distributable, applicable and controllable. The bait allows a constant and accurate control of its consumption by rodents. In the case of an extermination operation, the remaining parts of the bait can be reused or left on the long term. The composition of the bait ensures its attractiveness, acceptabilnoat for rodents even in the presence of feed, food and their residues. The bait of the present invention contributes to a reduction of about 75% in material deratization and to a reduction in cereal consumption of baits of about 95.25%, as well as to a reduction in the epithelium of active rodenticidal substances which are in most cases imported. The bait according to the invention will also be used for small-scale household household and the like, also taking into account the above-mentioned safety, hygiene and economic considerations. A comparison of the use of the baits of the present invention with the bait forms used so far shows that only 25% by weight of the bait form used so far is needed when using the first bait forms, i.e. the bait form used so far. to a procedure wherein, when using the bait of the invention, to a complex procedure, including the addition of consumable and consumed bait. Only 50 kg, as opposed to 200 kg of consumption, are required using existing, mainly loose baits, provided that the bait of the invention, not consumed by rodents, is not degraded and can be further used. Thus, it can be seen that not only the bait, about 75%, but also the savings of the rodenticide active substance, which is largely imported, but also significant savings in cereal consumption can be achieved. The cereal consumption of the bait according to the present invention is 9.5 kg versus 200 kg of the cereals in the old method of preparing the rodenticide bait in the above procedure. This means that the cereal savings are 95.25%. The improved effect of the formulation according to the invention is shown in the table.

The baits according to the invention can be used, for example, by placing them in rodent habitats, such as offices, warehouses, basements, attics, production areas, sanitary and sanitary facilities, sewers, and inserting them into rodent wells at their habitat. The bait can be set up by one trained worker, and the baits according to the invention can therefore be used by retailers as well as by specialists in specialized equipment.
