Abstract

Summary: Résumé: Zusammenfassung In three experiments, glyphosate (1.0 kg/ha) and aminotriazole (1.5 kg/ha) killed volunteer potatoes. Glyphosate (0.5 kg/ha) gave acceptable control in the field but not in the two pot experiments; in these latter, addition of ammonium sulphate to glyphosate improved its performance. Field applications of both herbicides at the end of May were less effective than those in June and July, because not all the sprouts had emerged in May. Aminotriazole killed those daughter tubers already pre sent, whilst glyphosate affected sprout viability and hence their ability to produce new plants. The practical potential of these two herbicides for the control of volunteer potatoes is discussed. Activité du glyphosate el de l'aminotriazole contre les repousses de pommes de terre et leurs tubercules fils Dans trois expériences, le glyphosate (1,0 kg/ha) et l'aminotria‐zole (1,5 kg/ha) ont tue les repousses de pommes de terre. Le glyphosate (0,5 kg/ha) a fait preuve d'une efficacité acceptable au champ mais pas dans les deux expériences en pots; dans celles‐ci, I'addition de sulfate d'ammonium au glyphosate a amélioré ses performances. Les applications au champ des deux herbicides à la fin de mai ont été moins efficaces que celles effectuées en juin et juillet parce que toutes les repousses n'étaient pas sorties en mai. L'aminotriazole a tué les tubercules fils déjà présents, alors que le glyphosate a affecté leur germina tion et par suite leur capacitéà produire de nouvelles plantes. La valeur pratique de ces deux herbicides pour lutter contre les repousses de pommes de terre est discutée. Die Wirkung von Gtyphosat und Aminotriazot auf Unkraut‐Kar‐toffelpflanzen und deren Tochterknollen In drei Versuchen wurden durch Glyphosat (1,0 kg/ha) und durch Aminotriazol (1,5 kg/ha) Unkraut‐Kartoffeln abgetotet. Glyphosat (0,5 kg/ha) ergab unter Feldbedingungen eine brauchbare Bekampfung, nicht jedoch in zwei Gefassver‐suchen; in letzteren wurde die Wirkung von Glyphosat durch den Zusatz von Ammoniumsulfat verbessert. Die Feldbehan‐dlung Ende Mai war bei beiden Herbiziden weniger wirksam wie im Juni und Juli, weil im Mai das Kraut noch nicht voll entwickelt war. Durch Aminotriazol wurden alle bereits vor‐handenen Tochterknollen getötet, wogegen Glyphosat das Kraut schädigte und damit auch die Bildung neuer Pflanzen beeinflusste. Es werden die Möglichkeiten diskutiert, die sich durch die beiden Herbizide für die Bekämpfung von Unkraut‐Kartoffeln ergeben.
