Description

Mittel zum Vernichten von Ackerunkräutern Die pflanzenvernichtende Wirkung sowohl der schwefligen Säure als auch ihrer Lösungen ist bekannt. Die unter dem Namen Rauchgasschäden zusammengefaßten Erscheinungen sind ebenfalls Vergiftungen von Pflanzen durch Schwefeldioxyd. Die schweflige Säure wirkt hier gleichmäßig auf alle Pflanzen ein, und zwar derart (s. N o a c k , Zeitschrift für angewandte Chemie, 1929, S. i23), daß durch die Ablenkung der photooxydativen Wirkung des Chlorophylls auf das Protoplasma die Pflanze vernichtet wird.Means for destroying arable weeds The plant-destroying The effects of sulphurous acid as well as its solutions are known. The under Phenomena summarized under the name smoke gas damage are also poisoning of plants by sulfur dioxide. The sulphurous acid acts here evenly all plants, in this way (see N o a c k, Journal for Applied Chemistry, 1929, p. I23) that by deflecting the photo-oxidative effect of chlorophyll on the protoplasm the plant is destroyed.

Es wurde nun gefunden, daß sich Schwefeldioxyd in geringen Konzentrationen, zweckmäßig in besonderen Zubereitungen angewendet, zur selektiven Vernichtung von Unkräutern in Halmfrüchten eignet. Gegen Hederich nimmt man z. B. bis zu 2o'oige wässerige Lösungen, gegen blühenden Hederich entsprechend mehr. Man kann die schweflige Säure auch in Form von Bisulfit anwenden. Auch stark schwefelhaltige Polysuifidlösungen sind brauchbar. Das Schwefeldioxyd entsteht dann erst durch Oxydation auf der Pflanze. Die Calciumpolysulfidlösung bereitet man aus 195 Schwefel, 56 Kalk, 4.oo Wasser und nimmt eine Spritzlösung von 6 % Polysulfid.It has now been found that sulfur dioxide can be found in low concentrations, expediently used in special preparations for the selective destruction of Weeds in crops. Against Hederich one takes z. B. up to 20'oige aqueous solutions, correspondingly more against blooming Hederich. You can use the sulphurous Use acid also in the form of bisulfite. Also high sulfur polysulfide solutions are useful. The sulfur dioxide then only arises through oxidation on the plant. The calcium polysulphide solution is prepared from 195 sulfur, 56 lime, 400 water and takes a 6% polysulfide spray solution.
