Description

Insektenvertilgungsmittel Wie gefunden wurde, lassen sich die vom Tetrahydronaphthol ableitbaren Äther bzw. deren Derivate und Substitutionsprodukte in ausgezeichneter Weise zur Insektenbekämpfung verwenden. Derartige Verbindungen sind z. B. a-Tetrahydronaphtholmethyl- bzw. -äthyläther und ß-Tetrahydronaphtholmethyl-bzw. -ätlivläther. Sie können entweder allein oder in Mischung mit anderen synthetischen oder natürlichen Insektiziden, z. B. Pyrethrum bzw. ihren in beliebiger Weise hergestellten Extrakten, Streck- und Haftmitteln, als Stäubemittel Lind Spritzmittel Verwendung finden. Durch Zusatz von viskosen Ülen, wie Paraffinöl u. dgl., läßt sich die Schwebefähigkeit solcher Spritzmittel noch steigern.Insecticides As has been found, the Tetrahydronaphthol derivable ethers or their derivatives and substitution products Use excellently for insect control. Such connections are z. B. a-Tetrahydronaphtholmethyl- or -äthyläther and ß-Tetrahydronaphtholmethyl- or. -ätlivläther. They can either be used alone or mixed with other synthetic or natural insecticides, e.g. B. pyrethrum or their produced in any way Extracts, extenders and adhesives, used as dusts and sprays Find. The ability to float can be reduced by adding viscous oils such as paraffin oil and the like such pesticides even increase.

Man hat zwar schon N aphthole für die Zwecke der Schädlingsbekämpfung vorgeschlagen, jedoch sind -diese, wie aus folgenden Vergleichsversuchen hervorgeht, völlig unbrauchbar.It is true that naphthols are already available for the purposes of pest control suggested, but these are, as can be seen from the following comparative tests, completely useless.

Ein Raum von i cbm Inhalt wurde mit einer größeren Anzahl Fliegen beschickt, worauf bei den in der Tabelle angegebenen Versuchen i. eine Lösung von gleichen Teilen ß=-"Z aphtliol und Aceton, 2. ß-Tetrahydronaphtliolmethyläther, 3. Aceton vernebelt wurde. Beispiel i Man zerstäubt in :einem von Fliegen stark besetzten Raume pro chm i bis 2 ccm ß-Tetrahydronaphtholmethyläther; nach kurzer Zeit ist eine restlose Abtötung erfolgt. Beispiel e Man löst 5 Teile a-Tetrahydronaphtholäthyläther in 5 Teilen Butylalkohol und versetzt mit 15 Teilen Emulgierungsmittel, z. B. einer 5oprozentigen Lösung des Natronsalzes der Dibutylnaphthalinsulfosäure. Hierauf wird auf ioo Teile mit Wasser verdünnt. Eine etwa 2prozentige Lösung dieser Stammlösung ergibt die hervorragend wirkende Gebrauchslösung.
