Description

Schädlingsbekämpfungsmittel Es wurde gefunden, daß Kupfer- oder Zinkphenolammoniak- bzw. Aminokomplexverbindungen sich sehr gut zur Desinfektion, zum Imprägnieren von pflanzlichen oder tierischen Stoffen und zur Saatgutbeizung eignen.Pesticides It has been found that copper or zinc phenol ammonia or amino complex compounds are very good for disinfecting, for impregnating vegetable or animal substances and suitable for seed dressing.

Die neuen Komplexverbindungen, welche in erster Linie als Schädlingsbekämpfungsmittel, zur Bekämpfung von Holzpilzen und Getreidekrankheiten dienen sollen, sind erhältlich durch Einwirkung von in Ammoniak oder Aminen gelösten Kupfer- oder Zinksalzen auf Lösungen von negativ substituierten, phenolische Hydroxylgruppen enthaltenden Verbindungen. So ist z. B. ein mit solchen Verbindungen imprägniertes Holz gegen die Angriffe der holzzerstörenden Pilze weitgehend geschützt. Ebenso wird das mit diesen Verbindungen nach einem der üblichen Verfahren gebeizte Saatgut weitgehend vor Krankheitsbefall geschützt.The new complex compounds, which are primarily used as pesticides, to combat wood fungi and cereal diseases are available by the action of copper or zinc salts dissolved in ammonia or amines Solutions of negatively substituted compounds containing phenolic hydroxyl groups. So is z. B. a wood impregnated with such compounds against the attacks the wood-destroying fungi are largely protected. It is the same with these connections seeds dressed by one of the usual methods largely before disease infestation protected.

Gegenüber den freien Phenolen und ihren bisher bekannten Salzen haben diese Komplexverbindungen den Vorteil, daß sie geruchlos und nicht flüchtig sind. Die Verbindungen sind zum Teil wasserunlöslich, teils schwer, teils leichter löslich. Soweit diese unlöslich sind, gelingt es teilweise, sie durch Zugabe von überschüssigen wäßrigen Aminen bzw. Ammoniak zu lösen. Da beim Verdunsten der überschüssigen Basen die ursprünglichen Verbindungen wieder unlöslich abgeschieden werden, so gelingt es, auf diese Weise dem zu imprägnierenden Material, wie Stoffgewebe, Holz, Torf, Kork USW., das Schutzmittel in einem Arbeitsgange in unlöslicher Form einzuverleiben. Selbstverständlich können die Komplexverbindungen, soweit sie in organischen Lösungsmitteln löslich sind, auch in dieser Form Verwendung finden. Vor den bekannten anorganischen Ammoniakkomplexverbindungen haben die neuen Körper den Vorteil, daß sie mit der Wirkung des Metalls auch noch die starke Wirkung des Phenols verbinden. Beispiel r Dinitrokresoläthylendiaminkupfer, in Wasser gelöst, hemmt das Wachstum von Coniophora in o,oz°/oiger Konzentration.Compared to the free phenols and their previously known salts, these complex compounds have the advantage that they are odorless and non-volatile. The compounds are partly insoluble in water, partly sparingly, partly more easily soluble. If these are insoluble, it is partially possible to dissolve them by adding excess aqueous amines or ammonia. Since the original compounds are insoluble again deposited when the excess bases evaporate, it is possible in this way to incorporate the protective agent in insoluble form in the material to be impregnated, such as fabric, wood, peat, cork, etc., in one operation. Of course, the complex compounds, provided they are soluble in organic solvents, can also be used in this form. The new bodies have the advantage over the well-known inorganic ammonia complex compounds that they combine the action of the metal with the strong action of the phenol. Example r Dinitrocresolethylenediamine copper, dissolved in water, inhibits the growth of Coniophora in oz% concentration.

Example s Trichlorocresol ethylenediamine zinc, dissolved in dilute alcohol, inhibits the growth of Penicillium in 0.06% concentration.
