Description

Saatguttrockenbeize, insbesondere zur Bekämpfung von Helminthosporium gramineum Die Streifenkrankheit der Gerste ist bekanntlich von allen durch chemische Mittel bekämpfbaren infektiösen Getreidekrankheiten am schwersten zu beseitigen. Wirksame Mittel gegen Streifenkrankheit sind auch ohne weiteres zur Bekämpfung von Weizensteinbrand, Gerstenhartbrand, Haferflugbrand und Fusarium brauchbar.Dry seed dressing, in particular for combating Helminthosporium gramineum The streak disease of barley is known to all by chemical Means of combating infectious cereal diseases the most difficult to get rid of. Effective remedies for streak disease are also readily available for combating Wheat stone brandy, barley brandy, oat brandy and Fusarium can be used.

Man hat bis jetzt gegen Streifenkrankheit nur Quecksilberverbindungen, und zwar meist teure und schwer herzustellende organische Verbindungen, mit Erfolg verwendet. Von "" den anorganischen Quecksilberverbindungen @' hat G a ß n e r (Arb. Biol. Reichsanst. II. Bd. S. 374) Quecksilbercyanid und Quecksilbercyanid-Cyankali gegen Steinbrandsporen im' Laboratorium versucht. Die Dosis curativa war bei beiden Verbindungen größer als 1,75 °/a Hg, die Dosis toxica war o,i5 °/o Hg.Up to now one has only mercury compounds against streak disease, mostly expensive and difficult to manufacture organic compounds, with success used. G a ß n e r (Arb. Biol. Reichsanst. II. Vol. P. 374) Mercury cyanide and mercury cyanide cyanide Tried against stone fire spores in the laboratory. The dose curativa was with both Compounds greater than 1.75% Hg, the toxica dose was 0.15% Hg.

Auch Gemische mehrerer Fungicide, zu denen zur Verstärkung auch Quecksilberverbindungen kommen können, wurden schon angewendet, und zwar in alkoholischer Lösung (zur besseren Abtötung der Sporen) oder in ammoniakalischer Lösung, um das Ausfällen von Kupfersalzen zu verhindern. An Stelle der ammoniakalischen Lösung können auch Doppelverbindungen wie Kupferammoniaksalze verwendet werden.Also mixtures of several fungicides, including mercury compounds for reinforcement can come, have already been used, in an alcoholic solution (for the better Killing the spores) or in ammoniacal solution to prevent the precipitation of copper salts to prevent. Instead of the ammoniacal solution, double compounds can also be used how copper ammonia salts are used.

Ouecksilbercyanidammoniak, durch Imprägnieren in Kaolin usw. zu einer Trockenbeize verarbeitet, hat sich nun als ein vorzügliches Mittel gegen Helminthosporium gramineum, den Erreger der Streifenkrankheit, erwiesen. Als Trockenbeizmittel beseitigt es bei sehr niedrigem Quecksilbergehalt nach den unten angegebenen Versuchen Streifenkrankheit vollständig, ohne das Getreide zu schädigen. Versuche: kranke Pflanzen Unbehandelt ............ - 5,6 Ouecksilbercyanidammo- niak als Trockenbeize, 150 g/Ztr ............. 2,o 0,3 Desgleichen, i5o g/Ztr.... 2,4 0,= - 150 g/Ztr.... 2,8 0,0 Mercury cyanide ammonia, processed into a dry stain by impregnation in kaolin etc., has now proven to be an excellent remedy against Helminthosporium gramineum, the pathogen that causes streak disease. As a dry dressing agent with a very low mercury content, according to the tests given below, it completely eliminates streak disease without damaging the grain. Try: sick plants Untreated ............ - 5.6 Mercury cyanidammo- niak as dry stain, 150 g / Ztr ............. 2, o 0.3 Likewise, i5o g / Ztr .... 2.4 0, = - 150 g / Ztr .... 2.8 0.0
