Description

Verfahren zur Unkrautbekämpfung Die günstige Wirkung der Sulfate, Nitrate und Chloride des Kupfers und des Eisens bei der Bekämpfung von Acker- und Gartenunkräutern ist bekannt.Weed control method The beneficial effect of sulfates, Nitrates and chlorides of copper and iron in the fight against arable and Garden weeds are known.

Nach vorliegender Erfindung ist es nun wesentlich vorteilhafter, an Stelle der obenerwähnten Schwermetallsalze, deren Anion keinerlei schädigende Wirkung auf die Unkräuter ausübt, solche Schwermetallsalze zu verwenden, deren Anion ebenfalls auf Unkräuter schädigend einwirkt. Als derartiges Anion wurde die Kieselfluorwasserstoffsäure erkannt, deren Wirkung gegen tierische Parasiten bereits bekannt war.According to the present invention, it is now much more advantageous to Place of the above-mentioned heavy metal salts, the anion of which has no harmful effect exercises on the weeds to use such heavy metal salts, their anion as well has a damaging effect on weeds. Hydrofluoric acid became such an anion recognized whose effect against animal parasites was already known.

Ein besonderer Vorteil der Verwendung von Schwermetall-Silicofluoriden, z.B. Eisensilicofluorid, ist darin zu erolicken, daß Eisensilicofluorid gegenüber dem Eisensulfat, Eisenchlorid oder Eisennitrat eine weit höhere unkrautschädigende Wirkung besitzt, also ein wirksames Unkrautvernichtungsmittel darstellt, und außerdem die in den meisten Fällen verwendeten eisernen Geräte nicht angreift. Das Eisensilicofluorid beispielsweise steht bezüglich der unkrautvernichtenden Wirkung etwa auf gleicher Höhe wie Kupfernitrit oder Kupfernitrat, die jedoch in eisernen Geräten infolge der Auszementierung" des Kupfers kaum angewandt werden können.A particular advantage of using heavy metal silicofluorides, e.g. iron silicofluoride, is to be found in that iron silicofluoride is opposite Iron sulfate, iron chloride or iron nitrate have a far higher weed damage Has an effect, so it is an effective herbicide, and also does not attack the iron devices used in most cases. The iron silicofluoride for example, it is about the same with regard to the weed-killing effect Height like copper nitrite or copper nitrate, which however in iron devices as a result the cementation "of the copper can hardly be used.

Die Silicofluoride der Schwermetalle, vor allem die des Kupfers, Eisens und Zinks, können für sich allein in wässeriger Lösung, kristallisiert und gemahlen als streufähiges Pulver, sowie zusammen mit anderen Mitteln, die entweder nur zum Strecken dienen oder auch so ausgewählt werden, daß die Wirkung der Silicofluoride verstärkt wird, angewandt werden.The silicofluorides of the heavy metals, especially those of copper and iron and zinc, on their own in aqueous solution, can be crystallized and ground as a sprinkle powder, as well as together with other means that either only for Stretching are used or selected so that the effect of the Silicofluoride be applied.

Von den erprobten Mischungen seien genannt i. 15 °/o Kupfersilicofluorid mit # 85 0'a Eisenvitriol, z. 2o % Eisensilicofluorid, 70 °/o Ammonsulfat, io °1o Ammonsalpeter.Of the mixtures tested, i. 15% copper silicofluoride with # 85 0'a iron vitriol, e.g. 20% iron silicofluoride, 70% ammonium sulphate, 10% 10 Ammonite nitrate.

Die genannten Kombinationen üben bereits in 1,8 bis 2,5 °/oiger Lösung eine vollkommene Wirkung aus.The combinations mentioned exert a perfect effect even in a 1.8 to 2.5% solution.

Für Streuzwecke werden die Silicofluoride allein oder mit den erwähnten Streckmitteln, zweckmäßig mit Torfpulver oder Kieselgur, vermischt verwandt. Eine besonders wirkungsvolle Form eines -Pulvers für Streuzwecke wird dadurch erzielt, daß eine trockene Mischung von Kieselgur mit Ferrohydroxyd oder Kupfercarbonat und Ammonnitrat mit wässeriger Kieselfluorwasserstoffsäure vermischt wird, wodurch nach dem Trocknen ein Produkt erhalten wird, das die wirksamen Silicofluoride in feinstverteilter bzw. in adsorbierter Form enthält.For scattering purposes, the Silicofluoride alone or with the mentioned Extenders, appropriately mixed with peat powder or kieselguhr, related. One A particularly effective form of powder for spreading purposes is achieved by that a dry mixture of kieselguhr with ferrohydroxide or copper carbonate and Ammonium nitrate mixed with aqueous silicofluoric acid is obtained, whereby after drying a product is obtained which the effective Silicofluoride contains in finely divided or in adsorbed form.
