Description

NagetierbekämpfUngsmittel Es wurde gefunden, daß a-Halogenpyrimidine, die in 4-Stellung eine tertiäre Aminogruppe und in 6-Stellung eine Methylgruppe tragen, hochgiftige, zur Vertilgung von Nagetieren geeignete Stoffe sind. Sie werden mit Ködern von diesen Tieren gut angenommen. Als besonders wirksam haben sich solche a-Halogenpyrimidine erwiesen, .die in 4.-Stellung eine durch niedere Akylgruppen substituierteAminogruppe, besonders eine Dimethylaminogruppe, gebunden enthalten. Als Halogen finden vorzugsweise Chlor und Brom Verwendung, aber auch Jodverbindungen sind brauchbar. Die .genannten Stoffe finden gewöhnlich in Form ihrer Salze in Verdünnung mit Streckmitteln ,und Köderstoffen, z. B. in Form verdünnter Lösungen, von Pulvern oder Pasten, gegebenenfalls in Mischung mit anderen geeigneten Nagetierbekämpfungsmitteln, Verwendung. Die Salze lösen sich ausreichend in Wasser, welche Lösungen Pastengrundlagen, z. B. von Stärke, Fetten oder Methylcellulose, zugesetzt werden können. Beispiel z 300:g z-Chlor-q.-dimethylamino-6-methylpyrimidinhydrochlorid werden in 4.o Liter Wasser gelöst, dem außerdem 13g eines wasserlöslichen roten Farbstoffes, wie Diamantfuchsin, zugesetzt sind. Diese Lösung wird in einem Bottich auf roo kg Weizen gegossen, der durch Rührer bewegt wird. Nachdem .die Körner die Lösung aufgenommen haben, werden sie ausgebreitet. Von diesem roten Giftgetreide genügen wenige Körner, um eine Maus zu töten. Entsprechende Wirkung zeigen die mit 2 -Brom -.4- dimethvlamino-6-znethvlpy rimi din und mit 2-Chlor-.j-methyläthylamino-6-methylpyrimidin hergestellten Giftkörner. Beispiel 2 Eine Paste zur Vertilgung von Ratten wird in der Weise hergestellt, daß einer üblichen Pastengrundlage 5oo g auf ioo kg der in Beispiel i genannten Verbindung zugesetzt werden. Zur Paste fügt man noch d0 g eines intensiven Farbstoffes, wie Alkaliechtgrün, um sie als Giftpaste kenntlich zu machen. Zu Ködern, wie Kartoffelbrei oder Essenresten, können etwa i o °/o der Paste zugefügt werden, um ein sicher wirkendes Rattenvertilgungsmittel zu schaffen. Ratten fressen die vergiftete Speise leicht und gehen danach in einigen Stunden ein.Rodent Control Agents It has been found that α-halopyrimidines, those in the 4-position a tertiary amino group and in the 6-position a methyl group are highly toxic substances suitable for the destruction of rodents. you will be well accepted with bait by these animals. These have proven to be particularly effective α-Halopyrimidines have been shown to have a lower alkyl group in the 4th position substituted amino group, especially a dimethylamino group, bound. The halogen used is preferably chlorine and bromine, but also iodine compounds are useful. The substances mentioned are usually found in the form of their salts in dilution with extenders, and baits, e.g. B. in the form of dilute solutions, of powders or pastes, optionally mixed with other suitable rodent control agents, Use. The salts dissolve sufficiently in water, which solutions are paste bases, z. B. of starch, fats or methyl cellulose, can be added. example z 300: g of z-chloro-q.-dimethylamino-6-methylpyrimidine hydrochloride are added to 4.o liters Dissolved water, which also contains 13g of a water-soluble red dye, such as diamond fuchsin, are added. This solution is poured onto roo kg of wheat in a vat is moved by stirrer. After the grains have absorbed the solution spread them out. A few grains of this red, poisonous grain are enough to make a mouse to kill. Corresponding effects are shown by those with 2 -Bromo -.4- dimethvlamino-6-znethvlpy rimi din and poison grains produced with 2-chloro-.j-methylethylamino-6-methylpyrimidine. Example 2 A paste for the extermination of rats is prepared in such a way that a conventional paste base 5oo g to 100 kg of the compound mentioned in example i can be added. To the paste is added d0 g of an intense dye, such as Alkali green to make it recognizable as a poison paste. To bait, like mashed potatoes or leftover food, about i o per cent of the paste can be added to make it look safe To create rat killers. Rats easily eat the poisoned food and then come in in a few hours.
