Description

Saatgutbeizmittel Bekanntlich sind Arylarsinoxyde, z. B. Phenylarsinoxyd, ausgezeichnete Fungicide und daher in der Schädlingsbekämpfung, insbesondere für die Zwecke der Saatgutbeizung, in vorteilhafter Weise verwendbar. Auch ist es bekannt, Phenylarsinsäuren und deren Derivate zum Beizen von Saatgut zu verwenden.Seed dressings It is known that aryl arsine oxides, e.g. B. phenylarsine oxide, excellent fungicide and therefore in pest control, especially for the purposes of seed dressing, usable in an advantageous manner. It is also known To use phenylarsinic acids and their derivatives for dressing seeds.

Es wurde nun gefunden, daß die Alkalisalze der aiylarsinigen Säuren, als deren Anhydride die Arylarsinoxyde aufzufassen sind, eine der der phenylarsinsauren Salze überlegene fLmgicide Wirkung haben und sich daher für die Zwecke der Saatgutbeize besonders eignen. Beispielsweise kann man mit einem Mittel, welches nur o, 8 % As in Form des phenylarsinigsauren Kaliums enthält und daneben aus indifferenten Streckmitteln besteht, bei der Beizung von Weizensaatgut nach der Methode der Tröckenbeizung unter Einstäubung von i Ztr. des Getreides mit i-5o g Beizmittel zur Bekämpfung des Weizensteinbrandes sehr gute Erfolge erzielen.It has now been found that the alkali salts of aiylarsinigen acids, the anhydrides of which are the aryl arsenic oxides, one of the phenyl arsenic acids Salts have superior fLmgicide effects and are therefore suitable for the purposes of seed dressing particularly suitable. For example, you can use an agent that only contains 0.8% As in the form of phenylarsinous potassium and also from indifferent extenders when dressing wheat seeds using the dry dressing method Dusting of 1 cent. Of the grain with 1-50 g of pickling agent to combat the wheat stone brandy achieve very good results.

Die arylarsinigsauren Alkalisalze können bei der Bereitung der Beizmittel zweckmäßig gleich in Gegenwart der in feiner Verteilung befindlichen indifferenten Stoffe, wie Kieselgur, Talkum usw.,- hergestellt werden. Zu diesem Zweck löst man z. B. 32 Teile Ätzkali in 5oo Teilen Alkohol, gibt zu dieser Lösung i oo Teile feiest gemahlene Kieselgur und trägt dann unter Rühren 5o.Teile Phenyl.-arsinoxyd ein. Nach 1/2stündigem Rühren wird die Masse bei 8o° getrocknet und alsdann mit q.oo Teilen naphtholpechsulfosaurem Calcium und i q.5o Teilen Talkum vermahlen.The arylarsinetic acid alkali salts can expediently be prepared in the presence of finely divided inert substances, such as kieselguhr, talc, etc., during the preparation of the pickling agent. For this purpose one solves z. B. 32 parts of caustic potash in 500 parts of alcohol, add 100 parts of finely ground kieselguhr to this solution and then add 50 parts of phenyl arsine oxide with stirring. After stirring for ½ hour, the mass is dried at 80 ° and then ground with 100 parts of calcium naphtholpechsulfosaurem and 100 parts of talc.
