Abstract

Bait for protecting stores from rats and mice consists of the active ingredient Diferacoum and a warning dye in a carrier which is polyethylene glycol and/or diethylene glycol. Pref. the dyestuff is Duasyn blue AG VP280. (Hoechst) or DOOW 305 Renastral-Bordo R new (Hoechst). The bait is a liq. and the carrier is polyethylene glycol PEG 100-600 separately or mixed and the soln. is mixed with water in ratio 1:2-4, esp. 3 vol. pts. Alternatively the bait is solid and the carrier is polyethylene glcyol PEG 1000-35000. USE/ADVANTAGE - The bait is readily accepted by the vermin, acts rapidly, is highly effective and easy to prepare. The bait smells and tastes fresh and sweet and is thus attractive to the vermin. As a liq. the vermin drink more of the bait than they would of fresh water. There is apparantly a synergistic effect between the diferacoum, polyethylene glycol and water. Transport of the poison is rapid and it reaches all the vital organs of the vermin. The bait can also be solid.

Description

Die Erfindung betrifft einen Köder für den Einsatz im Vorratsschutz gegen Ratten und Mäuse, bei dem als Wirkstoff Difenacoum eingesetzt ist, das einen Farb­ warnstoff enthält und in einen Trägerstoff eingebracht ist.The invention relates to a bait for use in Storage protection against rats and mice, where as Active ingredient Difenacoum is used, which is a color contains warning substance and introduced into a carrier substance is.

Bisher wird Difenacoum in trockenen Ködern eingesetzt. Meist wird als Trägerstoff Getreideschrot verwendet, in welchen Difenacoum gelöst in Äthanol, Äthylazetat, Glyzerol oder Polyäthylenglykol unter Rühren einge­ sprüht wird. Die Akzeptanz derartiger Köder ist insbesondere in der Lebensmittelvorratshaltung gering, da sich den Schädlingen dort attraktivere Nahrungsquel­ len bieten. Als Flüssigköder findet Difenacoum keine Anwendung, da es unlöslich in Wasser ist. Die anderen Lösungsmittel sind für Schädlinge wenig attraktiv, oft sogar abstoßend. Auch tritt die Wirkung dieses Giftes erst nach vielen Tagen oder Wochen ein.So far, Difenacoum has been used in dry baits. Mostly grain is used as a carrier, in which difenacoum dissolved in ethanol, ethyl acetate, Glycerol or polyethylene glycol inserted with stirring is sprayed. The acceptance of such baits is low, especially in food storage, because the pests have more attractive food sources there len offer. Difenacoum does not find any as a liquid bait Use because it is insoluble in water. The others Solvents are often not very attractive to pests even repulsive. The effect of this poison also occurs only after many days or weeks.

Die Erfindung vermeidet die Nachteile des Standes der Technik. Es ist die Aufgabe der Erfindung, einen den Wirkstoff Difenacoum enthaltenden Köder zu schaffen, der eine gute Akzeptanz bei den Schädlingen findet, schnell wirkt und eine hohe Wirksamkeit bei einfacher Herstellungsmöglichkeit aufweist.The invention avoids the disadvantages of the prior art Technology. It is the object of the invention, the one Creating bait containing active ingredient difenacoum which is well accepted by the pests, acts quickly and is highly effective with simple  Has manufacturing ability.

Überraschend wurde gefunden, daß bei einer hervorragenden Akzeptanz die Wirkung außerordentlich schnell und sicher eintritt, wenn als Trägerstoff Poly­ äthylenglykol (PEG) und/oder Diethylenglykole verwendet werden.Surprisingly, it was found that one excellent acceptance the effect extraordinary occurs quickly and safely when poly ethylene glycol (PEG) and / or diethylene glycols used will.

Der Köder läßt sich sowohl als Flüssigköder als auch als Festblock herstellen. Im einen Falle ist es zweckmäßig, wenn der Köder ein Flüssigköder ist, dessen Trägerstoff Polyäthylenglykol PEG 100 bis 600 allein oder im Gemisch ist, und wenn diese Lösung mit Wasser im Verhältnis 1:2 bis 4, vorzugsweise 3 Volumenteile zu mischen ist, im anderen Falle, wenn der Köder ein Festblock ist, dieser Trägerstoff PEG 1000 bis 35 000 ist.The bait can be used as both liquid bait and produce as a fixed block. In one case it is useful if the bait is a liquid bait, the Carrier polyethylene glycol PEG 100 to 600 alone or in a mixture, and if this solution with water in a ratio of 1: 2 to 4, preferably 3 parts by volume mix is, otherwise, if the bait is one Fixed block, this carrier PEG 1000 to 35 000 is.

Die überraschend gute Akzeptanz insbesondere bei Nagetieren trotz eines verwendeten Farbwarnstoffs dürfte darauf zurückzuführen sein, daß dieser Köder so frisch und süßlich riecht und schmeckt. Als Flüssigköder riecht und schmeckt er gut wie frisches, gesüßtes Wasser und lockt dadurch die Schädlinge an. Versuche haben ergeben, daß die Schädlinge von diesem Gemisch mehr aufnehmen als sie es beim Trinken von Frischwasser tun; Die Wirkung dieses Rodentizides ist so gut, da eine synergistische Wirkung zwischen Difenacoum, Polyäthylenglykol und Wasser besteht. Der Transport des Giftes verläuft außerordentlich schnell, und zwar in alle lebenswichtige Organe des Schädlings. Die Herstellung dieses Rodentizides ist höchst einfach:
In Polyäthylenglykol bzw. Diethylenglykol wird Difenacoum eingemischt, bis das Difenacoum vollständig emulgiert ist. Die enthaltene Emulsion ist völlig stabil, frostunempfindlich und verändert sich bei langem Stehen nicht.The surprisingly good acceptance, in particular in rodents, despite a color warning agent used, may be due to the fact that this bait smells and tastes so fresh and sweet. As a liquid bait, it smells and tastes like fresh, sweetened water and thus attracts the pests. Experiments have shown that the pests absorb more of this mixture than they do when drinking fresh water; The effect of this rodenticide is so good because there is a synergistic effect between difenacoum, polyethylene glycol and water. The poison is transported extremely quickly, to all vital organs of the pest. The preparation of this rodenticide is extremely simple:
Difenacoum is mixed into polyethylene glycol or diethylene glycol until the difenacoum is completely emulsified. The emulsion it contains is completely stable, insensitive to frost and does not change if you stand for a long time.

Es hat sich als besonders zweckmäßig erwiesen, als Farbwarnstoff einen in Glykol lösbaren, insbesondere das im Handel erhältliche, von der Hoechst AG hergestellte pulverförmige Duasyn-Blau A-G VP 280 oder das pulverförmige DOOW 305 Remastral-Bordo R neu zu verwenden. Dieser Farbwarnstoff wird nach dem Zumi­ schen von Difenacoum in das Polyäthylenglykol oder in die Lösung von Difenacoum in Polyäthylenglykol eingerührt. Dieser Farbwarnstoff ist in Polyäthylen­ glykol löslich. It has proven to be particularly useful as Color warning substance, a detachable in glycol, in particular that commercially available from Hoechst AG Powdered Duasyn Blue A-G VP 280 or the powdery DOOW 305 Remastral-Bordo R use. This color warning substance is after the Zumi Difenacoum in the polyethylene glycol or in the solution of difenacoum in polyethylene glycol stirred in. This color warning material is in polyethylene glycol soluble.
