Description

Selektiv wirkende, kupferhaltige Unkrautvertilgungsmittel Die vorliegende Erfindung betrifft selektiv wirkende, kupferhaltige Unkrautvertilgungsmittel.Selectively acting, copper-containing weedkillers The present one The invention relates to selectively acting, copper-containing weedkillers.

Man hat bereits vorgeschlagen, aus Kupfersalzen bestehenden Unkracütvernichtungsmitteln entweder Chloride öder Nitrate zuzusetzen. Demgegenüber bestehen die erfindungsgemäßen Unkrautvertilgungsmittel nun aus Gemischen eines Kupfersalzes mit Alkalichloriden und- -nitraten... Durch- den geineixi.-samen Zusatz dieser Stoffe zu-Kupfersalzen wird die unkrautvernichtende Wirkung der letzteren ganz besonders günstig beeinflußt, und es wird vor allen Drogeneine beschleunigte Wirkung erreicht. Die obenerwähnten bekannten Mittel müssen zur Erzielung einer entsprechenden Wirkung in sehr viel höheren Konzentrationen benutzt werden, so daß sie sich in ihrer Anwendung erheblich teurer stellten Tals die ,neuen Gemische; Es sind .auch Unkrautvertilgungsmittel bekanntgeworden, die aus anorganischen Säuren, z. B. ,arseniger Säure, und Alkalichloriden und -nitraten bestehen. Die Zusätze der genannten Salze zur arsenigen Säure sollen beispielsweise letztere in Lösung halten. Ein Rückschluß auf die besondere Wirkung der Mischung von Alkalichloriden und -nitraten auf Kupfersalze, nämlich Erhöhung der selektiven Wirksamkeit der letztgenannten, ließ sich aus den bekannten Mischungen in keiner Weise ziehen.Weed killers consisting of copper salts have already been proposed to add either chlorides or nitrates. In contrast, exist the invention Weedkillers now made from mixtures of a copper salt with alkali chlorides and nitrates ... By the common addition of these substances to copper salts the weed-killing effect of the latter is particularly favorably influenced, and an accelerated effect is achieved above all drugs. The above mentioned known means have to be very much in order to achieve a corresponding effect higher concentrations are used, so that they vary considerably in their application Tals made the new mixtures more expensive; They are also herbicides became known, which consists of inorganic acids, eg. B., arsenic acid, and alkali chlorides and nitrates exist. The additions of the salts mentioned to the arsenic acid should for example, keep the latter in solution. A conclusion about the special effect the mixture of alkali chlorides and nitrates on copper salts, namely increase the selective effectiveness of the latter could be deduced from the known mixtures in no way pull.

Weiterhin werden die ungünstigen Einflüsse der Kupfersalze durch die erfindungsgemäßen Zusätze auf die zu schützende Pflanze selbst wesentlich verringert. Man kann daher das Gemisch aus Kupfersalzen, Alkalinitraten und -chloriden z. B. zwecks Erzielung -einer besonders großen Beschleunigung -der Unkrautvernichtwig in-Kupferko"nzeiitrationeri verwenden, die normalerweise bereits eine weseantlic'he Schädigung,der zu schützenden Pflanzen hervorrufen würden.Furthermore, the unfavorable influences of the copper salts by the additives according to the invention on the plant to be protected itself is significantly reduced. You can therefore use the mixture of copper salts, alkali nitrates and chlorides z. B. for the purpose of achieving -a particularly large acceleration -der weed killers in-Kupferko "nzeiitrationeri use, which are normally already essential Damage that would cause the plants to be protected.

Bei den erfindungsgemäßen Mischungen braucht :ein bestimmtes Verhältnis der Kupfersalze zu den Alkalinitraten oder -chloriden nicht. .eingehalten zu werden. Beispiel i Teil Kupfersulfat, 2 Teile N.atriumnitrat, 2 Teile Natriumchlorid. Brei Verwendung von Kaliumsalzen tritt noch der Vorteil hinzu, daß diese gleichzeitig noch eine düngende Wirkung haben.In the case of the mixtures according to the invention: a certain ratio is required the copper salts to the alkali nitrates or chlorides not. .to be complied with. Example 1 part of copper sulfate, 2 parts of sodium nitrate, 2 parts of sodium chloride. Porridge Use of potassium salts has the added advantage that they do so at the same time still have a fertilizing effect.

Die ;erfindungsgemäße, fortschrittliche Wirkung ist gegenüber den bekannten Mitteln auf der Grundlage eines Kupfersalzes mit Zugabe entweder seines Chlorides oder Nitrates in der, folgenden Tabelle- von Vergleichsversuchen enthalten.
