Description
Mittel zur Bekämpfung schädlicher Insekten Es wurde gefunden, daß i, i-Di-fluoraryl-2, 2, 2-trichloräthane mit besonderem Vorteil zur Bekämpfung schädlicher Insekten. verwendet werdenkönnen.Agents for controlling harmful insects It has been found that i, i-Di-fluoroaryl-2, 2, 2-trichloroethane with particular advantage for combating harmful Insects. can be used.
Die Verbindungen sind zur Bekämpfung schädlicher Insekten im Obst-, Wein-, Garben und' Forstbau und in der Ackerwirtschaft, ferner auch zur Vernichtung von Ungeziefer, wie Kleiderläusen, Schaben, Fliegen, Mücken usw., hervorragend geeignet. Man kann die Mittel gegebenenfalls unter Zusatz von Netz-, Haft- und Dispergiermitteln und auch zusammen mit bekannten Fungiciden oder Insekticiden anwenden.The compounds are used to combat harmful insects in the fruit, Viticulture, sheaves and forestry and in agriculture, also for destruction from vermin such as clothes lice, cockroaches, flies, mosquitoes, etc., excellently suited. The agents can optionally be added with wetting agents, adhesives and dispersants and also use together with known fungicides or insecticides.
Man hat für die Bekämpfung von Insekten bereits Dichlordiphen.ylmethane vorgeschlagen. Diese Stoffe konnten aber in der Praxis die arsenikhaltigen Bekämpfungsmittel nicht ersetzen.Dichlordiphen.ylmethane is already available for combating insects suggested. In practice, however, the arsenic-containing pesticides could use these substances do not replace.
Die, durch Fluoratome substituierten i, i-Di-aryl-2, 2, 2-trichloräthane haben den Vorteil, daß sie rasch und sicher wirken, ohne eine schädliche Wirkung auf Menschen und Nutztiere auszuüben. Gegenüber den entsprechenden, durch Chloratome substituierten i, i-Di-aryl-2, 2, 2-trichloräthanen zeichnen sich die Fluorverbindungen dadurch aus, daß sie einen niedrigerem Schmelzpunkt besitzen, so daß die Verbindungen, leichter in, flüssige Form gebracht werden können, die für die Herstellung der für die praktische Anwendung benutzten Emulsionen in vielen Fällen vorteilhaft ist. Die fluorhaltigen Verbind -ungen sind außerdem schneller und stärker wirksam als die entsprechenden chlorsubstituierten Körper,- so daß man beispielsweise bei der Bekämpfung des Kornkäfers mit der Hälfte an wirksamem Stoff auskommen kann.The i, i-di-aryl-2,2,2-trichloroethanes substituted by fluorine atoms have the advantage that they work quickly and safely without any harmful effect exercise on humans and farm animals. Compared to the corresponding, by chlorine atoms substituted i, i-di-aryl-2, 2, 2-trichloroethanes are characterized by the fluorine compounds characterized in that they have a lower melting point, so that the compounds Can be more easily brought into liquid form, which is used for the manufacture of the for the practical application of the emulsions used is advantageous in many cases. The fluorine-containing compound -ung are also faster and stronger effective as the corresponding chlorine-substituted body, - so that one for example can manage with half of the active substance in the fight against the grain beetle.
Die Verbindungen können in an sich bekannter Weise durch Kondensation von Chloral mit Fluorbenzolem hergestellt werden. Beispiel Durch Vermischen von 5 Teilen i, i-Di-p-fiuorphenyl-2, 2, 2-trichloräthan mit io Teilen Zellpech und 8i5 Teilen Schlämmkreide wird ein Mittel hergestellt, das, bei Verwendung in Form einer i%igen Spritzbrühe gegen die verschiedensten Insekten ausgezeichnete Wirkung besitzt. Wenn man z. B. mit einer i%igen Brühe dieses Mittels die Innenwandungeines Glasstutzens bespritzt und nach dem Antrocknen des Belages Fliegen in den Stutzen setzt, so fallen diese bereits nach etwa 15 Minuten mehr oder weniger bewegungsunfähig zu Böden.The compounds can be formed in a manner known per se by condensation of chloral with fluorobenzene. Example By mixing 5 parts of i, i-di-p-fluorophenyl-2, 2, 2-trichloroethane with 10 parts of cell pitch and 8i5 parts whiting chalk is a means that, when used in the form a 1% spray mixture has excellent action against a wide variety of insects owns. If you z. B. with a 1% broth of this agent the inner wall of one Splashed glass nozzle and flies into the nozzle after the covering has dried sets, they become more or less immobile after about 15 minutes to floors.
Zur Herstellung von wirksamen Stäubemitteln genügen bereits 2% des wirksamen: Stoffes in Mischung, z. B. mit 98 0J0 Talkum.To produce effective dusts, 2% of the effective: substance in mixture, e.g. B. with 98 0J0 talc.
Andere geeignete Verbindungen für die Bekämpfung schädlicher Insekten sind z. B. i, i-Di-(p-fluoro-chlor-phenyl)-2, 2, 2-trichloräthan, i, i-Di-(pfluör-m-chlor-phenyl)-2, 2; 2-trichloräthan, i, i-Di-(p-fluor-phenyl)-i-chlor-2, 2, 2-trichloräthan.Other suitable compounds for the control of harmful insects are z. B. i, i-Di- (p-fluoro-chloro-phenyl) -2, 2, 2-trichloroethane, i, i-Di- (pluör-m-chloro-phenyl) -2, 2; 2-trichloroethane, i, i-di (p-fluorophenyl) -i-chloro-2, 2, 2-trichloroethane.
