Description

  

  Verfahren zum Beizen von Saatgut.    Der Formaldehyd besitzt eine anerkannt  gute     fungizide        Beizwirkung,    doch sind     die     durch     diesen    Stoff beim     Saatgut    veranlassten  Schädigungen, wie sie besonders durch die  Arbeiten von     Kiessling    (Journal für Land  wirtschaft, Band 66, 1918) und     Hurd    (Jour  nal of     Agriculture,        XX.    1920) aufgedeckt  wurden, derart gross, dass heute der Formal  dehyd von fortschrittlichen Landwirten kaum  noch zur Saatgutbeize verwandt wird.

     Es wurde nun gefunden, dass diese Schä  digungen des Formaldehyds dadurch vermie  den werden können, dass man ihm Chlor  wasserstoffsäure zusetzt. Dadurch wird eine  restlose Verdampfung des Formaldehyds vom  Saatgut     herbeigeführt    und so die Schaden  quelle beseitigt.

   Die restlose Verdampfung  des Formaldehyds ist dem Umstande zu ver  danken, dass er sich beim     Abdunsten    inner  halb einer Mischung mit Chlorwasserstoff  säure nicht polymerisiert.     hur        die        Polymeri-          sationsprodukte    des Formaldehyds äussern  aber, wie Müller und     Molz        (Fühlings    land  wirtschaftliche Zeitung 1914, Seite 742 bis  752) und später     Hurd    (Journal of Agricul-         ture    1920, Seite 209) festgestellt haben, nach  teilige Wirkungen auf das Saatgut.  



  Man kann solchen Präparaten noch be  liebige andere Fungizide, zum Beispiel       Quecksilberchlorid    oder     inerte    Füllstoffe zu  setzen.

  Method of dressing seeds. Formaldehyde is recognized as having a good fungicidal dressing effect, but the damage caused to seeds by this substance is, as it is particularly evident from the work of Kiessling (Journal für Landwirtschaft, Volume 66, 1918) and Hurd (Journal of Agriculture, XX. 1920 ) were discovered, so large that today the formaldehyde is hardly used by progressive farmers for seed dressing.

     It has now been found that this damage to the formaldehyde can be avoided by adding hydrochloric acid to it. This brings about complete evaporation of the formaldehyde from the seed and thus eliminates the source of damage.

   The complete evaporation of the formaldehyde is due to the fact that it does not polymerize when it evaporates within a mixture with hydrochloric acid. However, as Müller and Molz (Fühlings agricultural newspaper 1914, pages 742 to 752) and later Hurd (Journal of Agriculture 1920, page 209) found out, only the polymerisation products of formaldehyde have adverse effects on the seeds.



  You can add any other fungicides to such preparations, for example mercury chloride or inert fillers.
