Description

Verfahren zur Bekämpfung schädlicher Pilze. Die Verwendung von nitrierten Phenolen, und zwar in der Hauptsache von Dinitrophenolen und ihren Salzen, zum Schutz des Holzes gegen Fäulnis ist bekannt. Es wurde nun gefunden, daB die löslichen Salze von Nitrosophenolen, und zwar auch von solchen, die nur eine Nitrosogruppe im Molekül enthalten, ebenfalls eine sehr erhebliche hemmende Wirkung auf das Wachstum schädlicher Pilze ausüben und damit den für den Pflanzenschutz wichtigen Vorteil verbinden, lebende Organe höherer Pflanzen wenig zu schädigen. Als Beispiel geeigneter Verbindungen seien die Natronsalze des p-Nitrosophenols, des N itroso-m-kresols und der i-Nitroso-2-naphthol-3-karbonsäure genannt. Man kann die Verbindungen sowohl allein wie im Gemisch mit bekannten Konservierungsmitteln oder mit Streckungsmitteln anwenden. Beispiel i.Methods of combating harmful fungi. The use of nitrided Phenols, mainly dinitrophenols and their salts, for protection of wood against rot is known. It has now been found that the soluble salts of nitrosophenols, including those that have only one nitroso group in the molecule also contain a very significant inhibitory effect on the growth of harmful Exercise mushrooms and thus combine the important advantage for plant protection, little damage to living organs of higher plants. As an example of suitable connections be the sodium salts of p-nitrosophenol, nitroso-m-cresol and i-nitroso-2-naphthol-3-carboxylic acid called. The compounds can be used either alone or in admixture with known preservatives or apply with extenders. Example i.

Man imprägniert Kiefernholz mit-einer Lösung, die im Liter 3 g p-Nitrosophenolnatrium enthält, in üblicher Weise unter Anwendung von Vakuum und Druck. Das Holz ist gegen Pilzbefall immun. Beispiele. Man verwendet an Stelle des in Beispiel i genannten Nitrosophenolnatriums eine Mischung von 1,5 Teilen desselben Salzes und 7,5 Teilen Fluornatrium für jeden Liter der Lösung. Auch kann man das Nitrosophenolnatrium :durch die gleiche Gewichtsmenge Nitroso-m-kresolnatrium, Natronsalz des i-Nitroso-2-naphthols .oder Dinatriumsalz der i - Nitroso - 2 - naphthols oder Dinatriumsalz der i - Nitroso - 2 - naphthol - 3 - karbonsäure ersetzen.Pine wood is impregnated with a solution containing 3 g of sodium p-nitrosophenol per liter contains, in the usual way using vacuum and pressure. The wood is against Fungal attack immune. Examples. One uses in place of that mentioned in example i Sodium nitrosophenol is a mixture of 1.5 parts of the same salt and 7.5 parts Fluorosodium for every liter of the solution. You can also use the sodium nitrosophenol : by the same weight of nitroso-m-cresol sodium, sodium salt of i-nitroso-2-naphthol .or disodium salt of i - nitroso - 2 - naphthols or disodium salt of i - nitroso - Replace 2 - naphthol - 3 - carboxylic acid.

Beispiel 3. Example 3.

Zur Bodendesinfektion, z. B. gegen Kohlhernie, versetzt man den verseuchten Boden pro Kubikmeter mit 0,4 kg Nitrosonaphtholnatrium.For soil disinfection, e.g. B. against cabbage hernia, one relocates the contaminated one Soil per cubic meter with 0.4 kg of nitrosonaphthol sodium.
