Man kennt bereits eine große Anzahl von aliphatischen und aromatischen Quecksilberverbindungen. Schon im Jahre 1930 wurden merkurierte aliphatisch^ und aromatische Kohlenwasserstoffe für die Zwecke der Saatbeize in Vorschlag gebracht. In der deutschen Patentschrift 515 075 wird besonders darauf hingewiesen, daß merkurierte aromatische Kohlenwasserstoffe wesentlich besser fungicid wirken als merkurierte aliphatische Kohlenwasserstoffe.A large number of aliphatic and aromatic mercury compounds are already known. Already in 1930, aliphatic ^ and aromatic hydrocarbons were mercurated for the purpose the seed dressing brought up in proposal. In the German patent specification 515 075 it is particularly pointed out that that mercurized aromatic hydrocarbons have a much better fungicidal effect than mercured ones aliphatic hydrocarbons.

Phenylquecksilbersalze als Beiz-, Spritz- und Stäubemittel zur Vernichtung von schädlichen Mikroorganismen an Pflanzen werden in der schweizerischen Patentschrift 253 422 erwähnt. Das Löslichmachen der Phenylquecksilbersalze wird durch pH-Verschiebung in das saure oder alkalische Gebiet erreicht. Ein Löslichmachen der Phenylquecksilbersalze mit einem neutral reagierenden Lösungsvermittler ist bislang nicht bekanntgeworden.Phenylmercury salts as pickling, spraying and dusting agents for destroying harmful microorganisms on plants are mentioned in Swiss patent 253 422. The solubilization is achieved by the phenylmercuric p H -shift in the acidic or alkaline region. A solubilization of the phenyl mercury salts with a neutrally reacting solubilizer has not yet become known.

Es wurde nun gefunden, daß sich Zellpech als Lösungsvermittler für merkurierte aromatische Kohlen-Wasserstoffe, vorzugsweise Phenylquecksilberacetat, eignet.It has now been found that cell pitch can be used as a solubilizer for mercurized aromatic hydrocarbons, preferably phenyl mercury acetate.

Die Vorteile dieser Methode werden besonders in der praktischen Anwendung augenscheinlich.The advantages of this method are particularly evident in practical application.

Spritzt man z. B. auf die ersten grünen Blätter junger Apfelbäume dieselbe Menge eines gelösten Phenylquecksilberacetates — erstens mit Soda oder Bicarbonat, zweitens mit Sulfitpech —, so zeigt es sich, daß ζ. B. die mit Sulfitpech löslich gemachten Phenylquecksilbersalze doppelt so hoch konzentriert gespritzt werden können wie die mit Soda löslich gemachten Quecksilbersalze, ohne die Blätter 'zu verbrennen.If you spray z. B. on the first green leaves of young apple trees the same amount of a solution Phenylmercury Acetates - firstly with soda or bicarbonate, secondly with sulfite pitch - it turns out that ζ. B. the phenyl mercury salts made soluble with sulfite pitch sprayed twice as concentrated like the mercury salts made soluble with soda without burning the leaves.

809 695/57809 695/57

Zum Beispiel verbrannte bereits eine o,2°/0ige Lösung eines in Soda gelösten Phenylquecksilbersalzes die Blätter junger Apfelbäume, während dies bei einer o,4°/0igen Lösung eines mit Sulfitpech löslich gemachten Phenylquecksilbersalzes noch nicht der Fall war. Daraus ergibt sich der besondere Vorteil obengenannter Methode fm die Praxis.For example burned already an o, 2 ° / 0 solution of a dissolved in soda Phenylquecksilbersalzes the leaves of young apple trees, whereas this was not the case with an o, 4 ° / 0 solution of a Phenylquecksilbersalzes solubilized with Sulfitpech. This results in the particular advantage of the above-mentioned method in practice.

Beispielexample

Ein Spritzmittel folgender Zusammensetzung: 5% Phenylquecksilberacetat, 30% Zellpech, 0,5% Oleylmethyltaurid, 64,5% Natriumsulfat wird 0,20Z0Ig gegen Apfelschorf gespritzt.A spray with the following composition: 5% phenyl mercury acetate, 30% cell pitch, 0.5% oleyl methyl tauride, 64.5% sodium sulfate is injected 0.2 0 Z 0 Ig against apple scab.
