Description

Trockenbeizmittel Es ist bereits versucht worden, durch hohe Düngemittelgaben gleichzeitig eine Bekämpfung von Krankheitserregern im Boden vorzunehmen. So wollte beispielweise H i 1 t n e r durch starke Kalkstickstoffgaben den Weizensteinbrand bekämpfen, allerdings mit dem Ergebnis, daß nur dort, wo besonders große Gaben von Kalkstickstoff verabreicht wurden, eine günstige Wirkung desselben gegen Wenzensteinbrand sich zeigte. Da die fungizide Wirkung des Kalkstickstoffes an sich zu gering war, hat H i 1 t n e r auch bereits vorgeschlagen, seine Giftigkeit durch entsprechende Zusätze, z. B. Teeröl usw., zu erhöhen. Trockenbeizmittel mit Zusatz von Harnstoff, welche neben ihrer fungiziden Wirkung gleichzeitig oine gewisse Düngewirkung ausüben, wurden bisher noch nicht verwendet. Trockenbeizmittel, so z. B. Kupfer-, Quecksilber-, Arsenvrrbindungen oder andere für diesen Zweck getügnete Fungizide, werden im allgemeinen in größerer Menge als bei der Naßbeize angewandt. Trotzdem ist diese Substanzmenge an sich sehr unerheblich, und insbesondere bei der Beizung kleinerer Saatgutmengen, speziell Gemüsesämereien u. dgl., ergibt =sich der Nachteil, daß eine derartig geringe Menge an Beizmittel zur Anwendung kommen muß, bezogen auf die Saatgutmenge, daß ein Abwägen bzw. ein genaues Dosieren in der Praxis schwer .angängig ist.Dry dressing agents Attempts have already been made by applying high amounts of fertilizer to combat pathogens in the soil at the same time. So wanted For example, H i 1 t n e r the wheat stone brandy through the use of strong calcium cyanamide fight, however, with the result that only where particularly large gifts of Calcium cyanamide was administered, a beneficial effect of the same against Wenzenstein fire showed up. Since the fungicidal effect of calcium cyanamide itself was too low, H i 1 t n e r has already suggested its toxicity by appropriate Additives, e.g. B. tar oil, etc. to increase. Dry pickling agent with the addition of urea, which in addition to their fungicidal effect also exert a certain fertilizing effect, have not yet been used. Dry pickling agents, e.g. B. copper, mercury, Arsenic compounds or other fungicides suitable for this purpose are generally used used in larger quantities than with wet stain. Even so, this amount of substance is in itself very insignificant, and especially when dressing smaller amounts of seed, especially vegetable seeds and the like, there is the disadvantage that such a small Amount of seed dressing must be used, based on the amount of seed that weighing or precise dosing is difficult in practice.

Es wurde nun gefunden, daß man Trockenbeizmittel in vorteilhafter Weise mit Harnstoff in jedem Verhältnis mischen und auf diese Weise eine geringere oder erheblichere Streckung des Trockenbeizmittels erreichen kann. Beispielsweise kann man mit einer Mischung von ioo Teilen fein gemahlenem Harnstoff und ioo Teilen Kupfercarbonat ein ausgezeichnetes Trockenbeizmittel erhalten.It has now been found that dry pickling agents can be used in a more advantageous manner Mix way with urea in any ratio and in this way a lower one or more substantial stretching of the dry dressing agent. For example can be made with a mixture of 100 parts finely ground urea and 100 parts Copper carbonate is an excellent dry pickling agent.
