Description

Unkrautvertilgungsmittel. Es wurde gefunden, daß sich sowohl Formamid als auch die Salze der Ameisensäure bzw. diese Verbindungen enthaltende Mischungen oder Lösungen vorzüglich zur Bekämpfung von Unkraut, insbesondere von Hederich u. dgl., eignen. Zu diesem Zweck werden die verunkrauteten Felder, die mit Halmfrüchten bestellt sein können, einfach mit der betreffenden Verbindung bzw. der diese enthaltenden Mischung oder Lösung bestreut oder bespritzt, worauf nach kurzer Zeit die Unkrautpflanzen zu Grunde gehen, während die Halmpflanzen weiter gedeihen. Auf die Bodenbakterien wirken die genannten Verbindungen in keiner Weise schädigend; Formamid und Ammoniumformiat können sogar als Stickstoffquellen von diesen verwertet werden. Beispielsweise wurde ein Morgen eines mit Hederich bewucherten Haferfeldes mit ;,5 kg Formamid in Form einer 5prozentigen wäßrigen Lösung bespritzt. Nach a bis 3 Stunden begann der Hederich zu welken und sich zu verfärben. Am nächsten Tage waren die Hederichpflanzen vollständig abgestorben, während die Haferpflanzen praktisch unverändert waren und höchstens vereinzelte gelbe Flecken aufwiesen, die das weitere Wachstum in keiner Weise beeinträchtigten.Herbicides. It was found that both formamide as well as the salts of formic acid or mixtures containing these compounds or solutions excellent for combating weeds, especially by Hederich u. Like., are suitable. For this purpose, the weed-covered fields are covered with stalk crops can be ordered, simply with the relevant compound or the one containing it Mixture or solution sprinkled or sprinkled, whereupon after a short time the weed plants perish while the stalk plants continue to thrive. On the soil bacteria the compounds mentioned do not have a damaging effect in any way; Formamide and ammonium formate can even be used by these as nitrogen sources. For example, was one morning of an oat field overgrown with hederich with;, 5 kg of formamide in the form a 5 percent aqueous solution sprayed. Hederich began after a to 3 hours to wither and discolor. The next day the hederich plants were complete dead, while the oat plants were practically unchanged and at most exhibited isolated yellow spots which did not impair further growth in any way.
