Verfahren zur Bekämpfung von Schädlingen.
Es ist bereits bekannt, bei der Bekämpfung von pflanzlichen und tierischen Schädlingen Seife oder. seifenartig sich verhaltende Produkte, wie z. B. Salze von Sulfosäuren, mit zu verwenden, jedoch dienen sie hier lediglich als Lösungs-oder Emulgierungsmittel für die eigentlichen Insektizide bzw. Fungizide, wie z. B. Nikotin, Schwefel u. dgl. Auch hat man bereits aromatische Sulfosäuren selbst oder deren Salze in der Schädlingsbekämpfung verwendet, doch wirken derartige Sulfosäuren erst in einer Konzentration, bei der empfindlicher Pflanzen bereits stark geschädigt werden.
Es wurde nun gefunden, dass man zu Schädlingsbekämpfungsmitteln mit weit günstigeren Eigenschaften gelangt, nämlich zu solchen, die schon in sehr geringer Konzentration einwandfrei ohne Schädigung der Pflanzen wirken, wenn man phenolfreie Braunkohlenteerölfraktionen oder ihre Mischungen mit aromatischen oder hydroaromatischen Kohlenwasserstoffen sulfiert. An Stelle der Kohlenwasserstoffe selbst lassen sieh auch ihre Halogenderivat verwenden. Die neuen Mittel wirken nicht nur gegen Pflanzen- schädlinge, sondern auch gegen Ungeziefer auf Tier und Mensch. Selbst die bekanntlich nur schwer bekämpfbaren Blut-und Blattläuse lassen sich in kürzester Zeit sicher abtöten.
Die Sulfierungsprodukte können sowohl in konzentrierter wässeriger Lösung, wie auch in fester Form in den Handel gebracht werden. Man verwendet am besten das Natriumsalz in Konzentrationen von 0-5% und weniger, dioch werden auch stärkere Lösungen ohne Schädigung von Tieren und Pflanzen ertragen. Die Wirkung bleibt auch bei Zusatz saurer oder alkalischer Stoffe erhalten.
Beispiel :
Ein Gemisch von 1000 Teilen Solaröl von Braunkohlenteer und 500 Teilen Xylol werden bei 10--20'zuerst mit 1000 Teilen Schwefelsäure 100% ig und hierauf mit 1500 Teilen rauchender Schwefelsäure (65% SOg) behandelt. Die erhaltene Sulfosäure wird von der unverbrauchten Schwefelsäure und vom unveränderten Öl getrennt und in bekannter Weise in das Natriumsalz übergeführt. Zur Bekämpfung dar Blutlaus verwendet man eine 1 ige Lösung dieses Salzes, während gegen Blattlaus bereits eine 0-3-0'5% igue Lösung genügt. Eine Schädigung selbst empfindlicher Pflanzen tritt erst bei Konzentrationen von 2-3% auf.

Methods of combating pests.
It is already known to use soap or soap in combating plant and animal pests. products that behave like soap, such as B. salts of sulfonic acids to be used with, but they are used here only as solvents or emulsifiers for the actual insecticides or fungicides, such as. B. nicotine, sulfur and the like. Like. Aromatic sulfonic acids themselves or their salts have already been used in pest control, but such sulfonic acids only work in a concentration at which sensitive plants are already severely damaged.
It has now been found that pesticides with far more favorable properties are obtained, namely those which work perfectly even in very low concentrations without damaging the plants if phenol-free brown coal tar oil fractions or their mixtures with aromatic or hydroaromatic hydrocarbons are sulfated. Instead of the hydrocarbons themselves, you can also use their halogen derivatives. The new agents not only work against plant pests, but also against vermin on animals and humans. Even blood and aphids, which are known to be difficult to control, can be safely killed in a very short time.
The sulfonation products can be placed on the market both in concentrated aqueous solution and in solid form. It is best to use the sodium salt in concentrations of 0-5% and less, but stronger solutions can also be tolerated without harming animals and plants. The effect is retained even when acidic or alkaline substances are added.
Example:
A mixture of 1000 parts of solar oil from lignite tar and 500 parts of xylene is treated at 10-20 'first with 1000 parts of 100% sulfuric acid and then with 1500 parts of fuming sulfuric acid (65% SOg). The sulfonic acid obtained is separated from the unused sulfuric acid and from the unchanged oil and converted into the sodium salt in a known manner. A 1% solution of this salt is used to control blood lice, while a 0-3-0,5% solution is sufficient against aphids. Even sensitive plants will only be damaged at concentrations of 2-3%.
