Abstract
Summary; Résumé; Zusammenfassung Unrestricted weed growth reduced the yield of transplanted onions ( Allium cepa L.) by 26–48%. Hand‐weeding once, 42 days after transplanting reduced the yield loss to 15%. Application of oxadiazon (1.1–1.3 kg ai ha −1 ), pendimethalin (1.2–1.8 kg ai ha −1 ), oxyfluorfen (0.14–0.43 kg ai ha −1 ) and chlorthal‐dimethyl (8.3–13.1 kg ai ha −1 ) resulted in yields comparable to the hand‐weeded control (82–126%). When sprayed at transplanting these herbicides gave excellent and persistent control of grasses (86–100%). However, they were less effective on broad‐leaved weeds (38–94% control). Désherbage chimique de l'oignon repiqué (Allium cepa L.) dans la Gezireh soudanaise La croissance incontrôlée des mauvaises herbes réduit le rendement des oignons repiqués de 26–48%. Un désherbage manuel, 42 jours après le repiquage, ramène la baisse de rendement à 15%. L'application d'oxadiazon (1,1–1,3 kg ma ha −1 ), de pendiméthalin (1,2–1,8 ka ma ha 1 ), d'oxyfluorfen (0,14–0,43 ka ma ha −1 ) et de chlortal‐diméthyle (8,3–13,1 kg ma ha −1 ), a permis d'atteindre des rendements comparables aux témoins désherbés manuellement (82–126%). Lorsqu'ils ont été administrés au moment du repiquage, ces herbicides ont permis un contrôle efficace et persistant des monocotylédones (86–100%). Toutefois, ils se sont montrés moins efficaces à l'égard des dicotylédones (38–94% du témoin). Chemische Unkrautbekämpfung in verpflanzten Zwiebeln (Allium cepa L.) in der Region Gezira (Sudan) Ungehinderte Unkrautentwicklung in verpflanzten Zwiebeln ( Allium cepa L.) verringerte die Ernte um 26–48%. Eine Handjätung, 42 Tage nach dem Auspflanzen, reduzierte den Ernteverlust auf 15%. Die Applikation von Oxadiazon (1,1–1,3 kg ai ha −1 ), Pendimethalin (1,2–1,8 kg ai ha −1 ), Oxyfluorfen (0,14–0,43 kg ai ha −1 ) und Chlorthal‐ dimethyl (8,3–13,1 kg ai ha −1 ) erbrachte Ernten, die mit denjenigen, der von Hand gejäteten Kontrollparzellen vergleichbar waren (82–126%). Diese Herbizide, zur Ausflanzzeit ausgebracht, ergaben eine ausgezeichnete und andauernde Kontrolle von Gräsern (86–100%), während die Wirkung gegen breitblättrige Unkräuter geringer ausfiel (38–94%).
