Description

Schädlingsbekämpfungsmittel Gegenstand der Erfindung ist die Verwendung von Acyl-z, 2-dioxymethylen-q.-propylbenzolen der allgemeinen Formel in der R einen aliphatischen Kohlenwasserstoffrest bedeutet, als Schädlingsbekämpfungsmittel.Pesticides The invention relates to the use of acyl-z, 2-dioxymethylene-q.-propylbenzenes of the general formula in which R is an aliphatic hydrocarbon radical, as a pesticide.

Die erfindungsgemäß vorgeschlagenen Acyl-x, 2-dioxyrnethylen-q.-propylbenzole sind bereits für sich insekticid wirksam. Ihre technische Bedeutung liegt jedoch darin, daß sie die insektentötende Wirkung bekannter Insekticide, insbesondere der natürlich vorkommenden Pyrethrine, sowie der synthetisch hergestellten, den Pyrethrinen nahestehendenVerbindungen, wie des Allethrins, ferner der wirksamen Substanzen der Derriswurzelextrakte, bei gleichzeitiger Anwendung um ein Vielfaches zu erhöhen vermögen. Dieser synergistische Effekt der Acyl-r, 2-dioxymethylen-q.-propylbenzole ist insofern überraschend und technisch vorteilhaft, als man bisher genötigt war, zur Erzielung einer mit den neuen Mitteln vergleichbaren synergistischen Wirkungssteigerung schwerer zugängliche Dioxymethylenverbindungen zu verwenden, wie z. B. das =, 2-Dioxymethylenbenzol-.4-propylen-n-octyjsulfoxyd oder das z, 2-Dioxymethylenbenzol-q.-propyl-butoxyäthoxyäthoxymethylenbenzol. Gegenüber diesen bekannten Verbindungen zeichnen sich die erfindungsgemäßen Acyl-i, 2-dioxy-4-propylbenzole bei vergleichbarem Wirkungsgrad durch ihre leichte Zugänglichkeit aus. Sie können auf einfache Weise nach der Methodevon Frie d el-Cr af t s durchKondensationvon i, 2-Dioxymethylen-4-propylbenzol mit den entsprechenden Carbonsäureanhydriden oder Carbonsäurehalogeniden in Gegenwart eines Katalysators gewonnen werden. Als besonders vorteilhaft hat sich die Verwendung von Propionyl-i, 2-dioxy-4 propylbenzol als Synergist für Pyrethrine und die oben bezeichneten anderen Insekticide erwiesen. Diese Verbindung vermag die insekticide Wirkung z. B. der Pyrethrine in starkem Maße zu erhöhen. Da sich die Herstellung von Propionyl-i, z-dioxymethylen-4-propylbenzol sehr wirtschaftlich aus der entsprechenden aromatischen Komponente und dem leicht zugänglichen Propionylhalogenid bzw. Propionsäureanhydrid gestaltet, ist die Verwendung besonders dieses Acylabkömnnlings des i, 2-Dioxymethylen-4-propylbenzois gegenübers den bisher bekannten Synergisten in der Schädlingsbekämpfung mit erheblichen Vorteilen verbunden.The acyl-x, 2-dioxyrnethylen-q.-propylbenzenes proposed according to the invention are already insecticidal in themselves. However, their technical importance lies in that they have the insecticidal effect of known insecticides, especially the naturally occurring pyrethrins, as well as the synthetically produced pyrethrins related compounds, such as allethrin, as well as the active substances of Derris root extracts, when used at the same time, can be increased many times over capital. This synergistic effect of the acyl-r, 2-dioxymethylene-q.-propylbenzenes is surprising and technically advantageous insofar as it was previously necessary to achieve a synergistic increase in effectiveness comparable to the new agents to use more difficult to access dioxymethylene compounds, such as. B. the =, 2-Dioxymethylenbenzol-.4-propylene-n-octyjsulfoxyd or the z, 2-dioxymethylene benzene-q.-propyl-butoxyethoxyethoxymethylene benzene. Opposite to These known compounds are distinguished by the acyl-i, 2-dioxy-4-propylbenzenes according to the invention with comparable efficiency due to their easy accessibility. You can in a simple manner according to the method of Frie d el-Cr af t s by condensation of i, 2-Dioxymethylene-4-propylbenzene with the corresponding carboxylic acid anhydrides or Carboxylic acid halides are obtained in the presence of a catalyst. As special The use of propionyl-i, 2-dioxy-4 propylbenzene has proven advantageous Proven synergist for pyrethrins and the above-mentioned other insecticides. This compound is capable of the insecticidal effect z. B. the pyrethrins in strong To increase dimensions. Since the production of Propionyl-i, z-dioxymethylene-4-propylbenzene very economical from the corresponding aromatic component and the easy accessible propionyl halide or propionic anhydride, is the use especially this acyl derivative of i, 2-dioxymethylene-4-propylbenzois the previously known synergists in pest control with considerable advantages tied together.

Als weitere Schädlingsbekämpfungsmittel nach der Erfindung kommen vor allem solche in Betracht, die Acyl-i, 2-dioxymethylen-4-propylbenzole enthalten, in denen der Acylrest Acetyl, Butyryl, Valerianyl, Caproyl und Butoxyacetyl bedeutet. Beispiel Durch Aufsprühen von Pyrethrumextrakt auf Glasflächen wird ein insekticider Rückstand erzeugt, der Insekten, die mit den Flächen in Berührungskommen, abtötet. Bringt man z. B. Kornkäfer (Calandra granaria) 17 Stunden mit den so behandelten Glasflächen in Kontakt, so werden bei einem Aufwand von 1,9 Mikrogramm Pytrethrin (auf ioo°/jgesPyrethrinberechnete, natürliche Mischung von Pyrethrin I und II) je Quadratzentimeter Glasfläche mehr als 5001, der Versuchstiere abgetötet. Sprüht man Pyrethrin in Kombination mit Propionyl-i, 2-dioxymethylen-4-propylbenzol im Verhältnis x : io auf die Glasflächen, so genügen bereits o,12 Mikrogramm Pyrethrin in der Mischung jeQuadratzentimeter, umdieKornkäfer nach 17stündigem Kontakt zu mehr als 50 °/o abzutöten.As further pesticides come according to the invention especially those that contain acyl-i, 2-dioxymethylene-4-propylbenzenes, in which the acyl radical is acetyl, butyryl, valerianyl, caproyl and butoxyacetyl. Example By spraying pyrethrum extract on glass surfaces, an insecticider This creates residue that kills insects that come into contact with the surfaces. If you bring z. B. Corn beetle (Calandra granaria) 17 hours with those treated in this way Glass surfaces in contact are pytrethrin at an expense of 1.9 micrograms (natural mixture of pyrethrin I and II calculated on 100% pyrethrin) each Square centimeters of glass area more than 5001, the test animals killed. Sprays one pyrethrin in combination with propionyl-i, 2-dioxymethylene-4-propylbenzene im Ratio x: io on the glass surfaces, 12 micrograms of pyrethrin are sufficient in the mixture per square centimeter to the beetles after 17 hours of contact kill more than 50%.

Die insektentötende Wirkung der Pyrethrine wird durch Zusatz von Propionyl-i, 2-dioxymethylen-4-propylbenzol, mengenmäßig betrachtet, auf etwa das 15fache gesteigert.The insecticidal effect of pyrethrins is enhanced by the addition of propionyl-i, 2-dioxymethylene-4-propylbenzene, in terms of quantity, increased by about 15 times.
