Abstract
Summary: Résumé: Zusammenfassung Response of weeds and sugarbeets (Beta vulgaris L.) to post‐emergence treatments of phenmedipham and mixtures of phenmedipham plus EP 475 applied alone and as a complementary treatment with cycloate was evaluated in two field studies. The mixtures of phenmedipham plus EP 475, applied at 0.84 and 1–12 kg/ha a.i., reduced the stand of red‐root pigweed ( Amaranthus retroflexus L.) three to five times more than did phenmedipham. Post‐emergence treatments of phenmedipham alone, or mixtures of phenmedipham plus EP 475, applied as complementary treatments with cycloate reduced the average stand of foxtails (Setaria spp.), redroot pigweed, and kochia ( Kochia scoparia (L.) Schrad.) by 82 to 94 %. With the complementary treatments, this level of weed control was obtained by reducing the rate of either cycloate or the post‐emergence herbicide treatment. Complementary treatments of cycloate plus phenmedipham, or the mixtures of phenmedipham plus EP 475, reduced sugarbeet seedling vigour temporarily, but they did not reduce the stand or yield. Désherbage des betteraves sucriéres avec le cycloate, le phenmédiphame et le produit EP 475 La réaction des mauvaises herbes et des betteraves sucrieres (Beta vulgaris L.) a étéévaluée dans deux essais au champ, à la suite de traitements effectues avec le phenmédiphame et des melanges de phenmfediphame et de EP 475 appliqués seuls et comme traitements compléementaires du cycloate. Les mé1anges de phenmé diphame plus EP 475, appliques a 0,84 et 1,12 kg/ha m.a. ont réduit le dé veloppement de l'amarante (Amarantus retroflexus L.) 3 à 5, fois plus que le phenmédiphame. Les traitements de post‐levé e avec le phenmédiphame seul ou avec les mélanges phenmé diphame EP 475 appliqués en complément d'un traitement avec le cycloate ont rdduit le développement moyen des sétaires (Setaria spp), de l'amarante et du Kochia (Kochia scoparia (L.) Schrad.) de 82 à 94%. Avec les traitements complé‐mentaires ce niveau de désherbage a été obtetiu en réduisant le taux soit du cycloate soit du traitement herbicide de post‐Ievée. Les traitements compl6mentaires avec le cycloate plus le phenmédiphame ou les mélanges de phenmédiphame plus EP 475 ont réduit temporairement la vigueur des plantules de betteraves mais n'ont pas eu d'influence sur le développement ni sur le rendement. Unkrautbekämpfung in Zuckerrüben mit Cycloat, Phenmedipham und EP 475 In zwei Feldversuchen wurde die Reaktion von Unkräutern und Zuckerruben (Beta ulgaris L.) auf Nachauflauf behand‐lungen mit Phenmedipham und Mischungen von Phenmedipham mit EP 475 sowohl bei alleiniger Ausbringung als auch nach zusätzlicher Behandlung mit Cycloat unter‐sucht. Die Mischungen von Phenmedipham mit EP 475 in Aufwandmengen von 0–84 und 1.12 kg/ha A.S. fuhrten zu einer drei‐ bis fünffach stärkeren Reduktion des Zurück‐gekrümmten Fuchsschwanzes (Amaranthus retrofiexus L.) als Phenmedipham. Wurden Phenmedipham allein oder Mischungen von Phenmedipham und EP 475 als zusStzliche Nachauflauf‐Behandlung zu Cycloat gegeben, so verringerte sich der durchschnittliche Bestand an Borstenhirsen (Setaria spp.) und Besenkraut (Kochia scoparia (L.) Schrad.) um 82 bis 94%. Bei den Zusatzbehandlungen wurde der gleiche Wirkungsgrad mit verringerten Aufwandmengen von Cycloat Oder dem im Nachauflauf eingesetztem Herbizid erzielt. Die zusatzlichen Behandlungen von Cycloat plus Phenmedipham Oder den Mischungen aus Phenmedipham und EP 475 hemmten zeitweilig das Wachstum der Keimpflanzen von Zuckerruben, die Bestandesdichte und der Ertrag wurden jedoch nicht beeinflusst.
