  Saatbeize. 



   In dem deutschen Reichspatent Nr. 397836 ist gezeigt worden, dass die fungizide Wirkung alkalilöslicher Verbindungen, welche Quecksilber komplex gebunden enthalten, dadurch wesentlich gesteigert werden kann, dass man Salze der Zyanwasserstoffsäure bzw. Ferrozyanwasserstoffsäure beimischt. 



   Es wurde nun gefunden, dass diese Erhöhung des fungiziden Wertes nicht auf die Salze der Zyanwasserstoffsäure und   Ferrozyanwasserstoffsäure beschränkt   ist, sondern auch den Salzen der Jodwasserstoffsäure zukommt. Da letztere an sich keine fungizide Wirkung   1 esitzen,   musste es   überraschen,   dass durch ihre einfache Zumischung eine weit bessere sporenabtötende Wirkung erzielt wird, als wenn man   alkalilösliche   organische Quecksilberkomplexverbindungen allein verwendet. 



   Beispiel : 25 Gewichtsteile   o-Kresolqueeksilberhydroxyd   werden mit 10 Gewichtsteilen Jodkalium gemischt. 0-5 Gewichtsteile dieser Mischung werden mit Wasser und Alkali zu 1 1 gelöst. Die mit dieser Lösung behandelten Steinbrandsporen keimen nicht mehr aus, während bei der Verwendung einer auf denselben Queeksilbergehalt abgestimmten Lösung von   o-Kresolqueeksilberhydroxyd   allein noch Keimung eintritt.

  Seed dressing.



   In the German Imperial Patent No. 397836 it has been shown that the fungicidal effect of alkali-soluble compounds which contain mercury in complex bound form can be increased significantly by adding salts of hydrocyanic acid or hydrocyanic acid.



   It has now been found that this increase in the fungicidal value is not limited to the salts of hydrocyanic acid and ferrocyanic acid, but also applies to the salts of hydroiodic acid. Since the latter have no fungicidal effect per se, it was surprising that simply adding them in has a far better spore-killing effect than using alkali-soluble organic mercury complex compounds alone.



   Example: 25 parts by weight of o-cresol queeksilver hydroxide are mixed with 10 parts by weight of potassium iodide. 0-5 parts by weight of this mixture are dissolved to 1 liter with water and alkali. The stone blight spores treated with this solution no longer germinate, whereas when a solution of o-cresol queeksilver hydroxide is used alone, germination occurs.
