Description
Zur Bekämpfung von Schädlingen, insbesondere Nagetieren, haben sich Metallphosphidverbindungen als ausgezeichnet wirksam erwiesen. Es genügt die Aufnahme einer verhältnismäßig kleinen Menge, um den Schädling mit Sicherheit abzutöten. Hauptsächlich wird Zinkphosphid für diese Zwecke verwendet. Ein Nachteil der Metallphosphidverbin'-dungen ist ihre leichte Zersetzbarkeit durch Säuren, Laugen und selbst durch Wasser. Die Metallphosphide können deshalb nur in Verbindung mit trockenen Köderstoffen·, wie z. B. Getreide, verwendet werden.To control pests, especially rodents, metal phosphide compounds have been used Proven to be extremely effective. It is sufficient to take in a relatively small amount to kill the pest with certainty. Mainly zinc phosphide is used for these purposes. A disadvantage of the metal phosphide compounds is their easy decomposability by acids, Alkalis and even water. The metal phosphides can therefore only be used in conjunction with dry bait substances, such as B. cereals can be used.
Für bestimmte große Anwendungsgebiete, z. B. zur Ratten-, Wühlmaus- und Werrenbekämpfung, ist jedoch die Verwendung einer streichbaren Paste erforderlich, die auch in Verbindung mit nassen Köderstoffen, z. B. Kartoffelbrei, frischen Rüben usw., gebraucht werden kann.For certain large areas of application, e.g. B. to control rats, vole and advertising, however, the use of a spreadable paste is required, also in conjunction with wet Bait substances, e.g. B. mashed potatoes, fresh beets, etc., can be used.
Die Herstellung einer solchen haltbaren Paste stößt wegen der Zersetzlichkeit der Metallphosphide auf Schwierigkeiten. Die Verwendung von wasserhaltigen, plastischen Stoffen, ζ. Β. Agar-Agar, Methylcellulose, verbietet sich, da das Phosphid in einer solchen; Paste sich zersetzt. Auch die Verwendung reiner Fette, z. B. Schweinefett, führt nicht zum Erfolg, da bereits der geringe Wassergehalt und die bei längerem Lagern entstehenden Fettsauren das Metallphosphid zersetzen.The manufacture of such a durable paste is uncomfortable because of the decomposability of the metal phosphides on difficulties. The use of water-based, plastic materials, ζ. Β. Agar-agar, methyl cellulose, Prohibited as the phosphide in such a; Paste decomposes. Also the use pure fats, e.g. B. pork fat, does not lead to success, since the low water content and the fatty acids formed during prolonged storage decompose the metal phosphide.
Es wurde gefunden, daß als Trägerstoff für Metallphosphidpasten hochmolekulare Kohlenwasserstoffe, wie z. B. Vaseline, geeignet sind. Obwohl man erwarten sollte, daß solche indifferenten Ver-It has been found that, as a carrier for metal phosphide pastes, high molecular weight hydrocarbons, such as B. Vaseline are suitable. Although one should expect that such indifferent
bindungen, die den Darm unzersetzt passieren und sogar noch als Gleitmittel wirken, die Einwirkung des Giftstoffes weitgehend verhindern würden, zeigte sich überraschenderweise, daß die Abtötung trotzdem rasch und sicher, auch bei Aufnahme von kleinen Mengen der Giftpaste, eintritt. Die Wirkung wird auch bei Verwendung von wasserhaltigen Köderstoffen, z.B. Kartoffelbrei, erzielt, wobei hier die hochmolekularen Kohlenwasserstoffe in idealer Weise das empfindliche Zirikphosphid vor dem Einfluß des Wassers schützen.bindings that pass through the intestine undecomposed and even act as lubricants are affected of the toxin would largely prevent, it was surprisingly found that the destruction nevertheless occurs quickly and safely, even if small amounts of the poisonous paste are absorbed. The effect is also obtained when using water-based Bait substances, e.g. mashed potatoes, achieved, with the high molecular weight hydrocarbons in ideal Way to protect the sensitive Zirikphosphid from the influence of water.
Die nach diesem Verfahren hergestellte Paste läßt sich daher ohne weiteres in Verbindung mit allen in Frage kommenden Ködern verwenden.The paste produced by this process can therefore be easily combined with use all bait in question.
