Description
Winterspritzmittel zum Bekämpfen von Schädlingen an unbelaubten Pflanzen Die Erfindung betrifft ein Mittel zum Bekämpfen von Schädlingen an unbelaubten Pflanzen mittels sogenannter Winterspritzmittel.Winter spray for combating pests on leafy plants The invention relates to an agent for controlling pests on non-leafy plants by means of so-called winter spraying agents.
Es ist bekannt, Dinitroorthokresole, besonders Dinitro-3, g-methyl-a-phenol oder deren Ammoniumsalze, als aktive Bestandteile in Schädlingsbekämpfungsmitteln anzuwenden. Diese Mittel können in bekannter Weise Füllstoffe, Lösungsmittel, Dispergiermittel usw. enthalten. Auch andere Stoffe mit toxischen Eigenschaften können zwecks Erhöhung der Wirkung und bzw. oder zur Erzielung einer spezifischen Wirkung zugesetzt werden. Oft werden die Dinitrokresole in Mineralöl, besonders hochraffiniertem Schmieröl, gelöst und diese Lösungen in Wasser emulgiert. Es ist bekannt, daß Dinitroorthokresole in saurem Medium die größte Wirkung besitzen. Wahrscheinlich ist dies so zu erklären, daß die Verbindungen in undissoziiertem Zustand Schädlingen gegenüber größere Toxizität haben. Es wäre dann begreiflich, daß, wie festgestellt wurde, Salze im allgemeinen geringere Wirkung haben wie die Dinitrokresole selbst.It is known that dinitroorthocresols, especially dinitro-3, g-methyl-a-phenol or their ammonium salts, as active ingredients in pesticides apply. These agents can be fillers, solvents, dispersants in a known manner etc. included. Other substances with toxic properties can also help to increase the effect and / or are added to achieve a specific effect. The dinitrocresols are often found in mineral oil, especially highly refined lubricating oil, dissolved and these solutions emulsified in water. It is known that dinitroorthocresols have the greatest effect in an acidic medium. This can probably be explained by that the compounds in the undissociated state are more toxic to pests to have. It would then be understandable that, as has been stated, salts in general have less effect than the dinitro cresols themselves.
Es wurde gefunden, daß überraschenderweise Lösungen oder Suspensionen, welche neben Dinitroorthokresol dessen Ammoniumsalz enthalten, eine hohe Wirksamkeit besitzen, welche größer ist als die Summe der Wirksamkeiten der Komponenten. Dies trifft auch zu, wenn die Bekämpfungsmittel nach der Erfindung bei niedrigeren Temperaturen angewandt werden. Das Verhältnis zwischen den Mengen des Dinitroorthokresols und des Ammoniumsalzes desselben kann innerhalb weiter Grenzen variieren; 4o bis 8o Gewichtsprozent kann als Ammoniumsalz vorhanden sein.It has been found that, surprisingly, solutions or suspensions, which contain its ammonium salt in addition to dinitroorthocresol, are highly effective which is greater than the sum of the efficacies of the components. this also applies when the control agents according to the invention at lower temperatures can be applied. The ratio between the amounts of dinitroorthocresol and the ammonium salt thereof can vary within wide limits; 4o to 80 percent by weight can be present as the ammonium salt.
Die Schädlingsbekämpfungsmittel nach der Erfindung können sowohl durch Vermischung der Komponenten wie durch partielle Neutralisation des Dinitroorthokresols mit Ammoniak hergestellt werden. In vielen Fällen ist es zweckmäßig, nach der Herstellung der Mischung diese zu einem feinen Pulver zu vermahlen, vorzugsweise in Gegenwart eines Füllstoffes wie Kieselgur, Kaolin, Kreide oder Gips. Es ist auch möglich, die partielle Neutralisation mit Ammoniak, in diesem Fall vorzugsweise mit gasförmigem Ammoniak, erst nach Vermischung des Dinitroorthokresols mit dem Füllstoff stattfinden zu lassen.The pesticides according to the invention can both by Mixing of the components as by partial neutralization of the dinitroorthocresol be made with ammonia. In many cases it is useful after manufacture the mixture to grind them to a fine powder, preferably in the presence a filler such as kieselguhr, kaolin, chalk or plaster of paris. It is also possible, partial neutralization with ammonia, in this case preferably with gaseous Ammonia, take place only after the dinitroorthocresol has been mixed with the filler allow.
Die erhaltenen Mischungen können eventuell nach Zugabe von Stärke und ähnlichen Stoffen zu Plätzchen gepreßt werden, die am Gebrauchsort in Wasser aufgeschwemmt werden.The mixtures obtained can possibly after the addition of starch and similar substances are pressed into cookies that are placed in water at the place of use to be bloated.
Beispiel 28 kg Dinitro-3, 5-methyl-2 phenol, 46 kg des Ammoniumsalzes dieser Verbindung und 26 kg Kieselgur wurden durch gemeinsames Vermahlen innig gemischt. i4o g der erhaltenen Mischung wurden aufgeschwemmt in ioo kg Wasser von 3°. Mit dieser Flüssigkeit wurden bei 6° Apfelbäumebespritzt, die mit Blattläuseeiern besetzt waren. Die Eier wurden praktisch vollständig abgetötet.Example 28 kg of dinitro-3, 5-methyl-2 phenol, 46 kg of the ammonium salt this compound and 26 kg of kieselguhr were intimately mixed by grinding together. 14o g of the mixture obtained were suspended in 100 kg of water at 3 °. With this liquid was sprayed at 6 ° on apple trees populated with aphid eggs was. The eggs were practically completely killed.
Mit Flüssigkeiten, welche äquivalente Mengen des Dinitroorthokresols oder des Ammoniumsalzes an sich enthielten, d. h. ioo g Dinitroorthokresol und iio g Ammoniumsalz auf ioo kg. Wasser von 3°, wurden unter im übrigen gleichen Umständen nur Abtötungen von 75 °/o, erzielt.With liquids containing equivalent amounts of the dinitroorthocresol or contained the ammonium salt per se, d. H. ioo g dinitroorthocresol and iio g of ammonium salt to 100 kg. Water of 3 °, were under otherwise identical circumstances deaths of only 75 per cent were achieved.
