Description

Verfahren zur Bekämpfung von Schädlingen in geschlossenen Räumen In den Patenten 597 554 und 625 865 wird die Verwendung der Doppelverbindungen von anorganischen Halogeniden mit Estern, Äthern, Aldehyden, Ketonen und sonstigen für die Schädlingsbekämpfung geeigneten Verbindungen für die Bekämpfung von Schädlingen in geschlossenen Räumen beschrieben. Die Anwendung geschieht dabei in der Weise, daß die Doppelverbindungen durch Wasser oder feuchte Luft in den zu begasenden Räumen zersetzt oder die entwickelten Dämpfe in diese Räume eingeführt werden.Method for combating pests in closed spaces Patents 597 554 and 625 865 describe the use of double compounds of inorganic halides with esters, ethers, aldehydes, ketones and other compounds suitable for pest control for combating pests in closed spaces. The application takes place in such a way that the double compounds are decomposed by water or moist air in the spaces to be fumigated or the vapors developed are introduced into these spaces.

Es wurde nun weiter gefunden, daß man bei der Bekämpfung von Schädlingen in lose liegenden Körner- und Hülsenfrüchten in einfacher Weise zum Ziele gelangt, wenn man die genannten Doppelverbindungen in das zu behandelnde Gut einmischt. Überraschenderweise zeigt sich nämlich, daß selbst die bei trocken neingelagertem Gut anhaftende natürliche Feuchtigkeit zu seiner so schnellen Zersetzung der Doppelverbindungen ausreicht, um trotz der Absorption der entwickelten Gase durch das Gut und nicht zu vermeidender Undichtigkeiten beim Abdichten .die für die Vernichtung der Schädlinge notwendige Konzentration zu erzielen.It has now been found that one can control pests achieves the goal easily in loosely lying grains and pulses, if the double compounds mentioned are mixed into the material to be treated. Surprisingly namely, it shows that even the natural adhering to goods that have not been stored dry Moisture is sufficient for its rapid decomposition of the double compounds, to despite the absorption of the evolved gases by the good and unavoidable Leaks when sealing. The necessary for the destruction of the pests Achieve concentration.

Unter Umständen ist @es vorteilhaft, die Doppelverbindungen, gemischt, mit Neutralisierungsmitteln, wie Kalkoder Magnesia, -oder mit reinen Streckmitteln, wie Talkum ,oder Biolus, zu verwenden. Auch steht einer Mitverwendung anderer bekannter fester insekticid ioder baktericid wirkender Mittel nichts im Wege.Under certain circumstances @es is advantageous, the double connections, mixed, with neutralizing agents such as lime or magnesia, or with pure extenders, like talc, or biolus, to use. There is also a use of other well-known nothing in the way of solid insecticidal or bactericidal agents.

Das Verfahren (eignet sich z. B. zur Bekämpfung von Kornkäfern in Lagerhäusern, Getreidespeichern und Silos. Ebenso kann man die Schädlinge anderer Nahrungs- und Futtermittel; z. B. Erbsen- und Linsenkäfer in Hülsenfrüchten, vernichten.The method (is suitable e.g. for combating grain weevils in Warehouses, granaries and silos. Likewise one can pest others Food and feed; z. B. pea and lentil beetles in legumes, destroy.

Beis piiel Ein Behälter von etwa r cbm Inhalt wird mit 15 Zentner seines stark von Kornkäfern befallenen Getreides gefüllt. Gleichzeitig werden 6oo g seiner Chlormagnesium - Äthylformiat-Djoppelverbindung mit einem Gehalt von ,etwa 5o0jö an Ester eingemischt. Nach 24stündiger Einwirkung sind die Käfer restlos abgetötet.Example A container with a volume of about r cbm is filled with 1 5 quintals of his grain, which is heavily infested with grain beetles. At the same time 600 g of its chloromagnesium - ethyl formate double compound with a content of about 50% of ester are mixed in. After 24 hours of exposure, the beetles are completely killed.
