Abstract

Summary: Résumé: Zusammenfassung In a series of experiments carried out in the Leeton‐Yanco area of southern New South Wales, molinate was applied to drill‐sown rice at rates ranging from 2.24 to 6.73 kg/ha, and at times ranging from pre‐sowing to 36 days after sowing‐Applications were made to dry soil, and pre‐sowing applications were shallowly incorporated. All other treatments were followed within 24 h by either a flushing irrigation, or by permanent flooding All molinate applications reduced Echinochloa spp. populations but best results were obtained with early post‐emergence applications. At this time of application 3.36 kg/ha was usually as effective as higher rates. Molinate caused no damage to the rice crop, and herbicide application resulted in yield responses where significant Echinochloa spp. infestations were present. Le molinate pour la lutte contre les Echinochloa spp. dans les cultures de riz en Nouvelle Galles du Sud Dans une série d'essais réalisés dans la région du Leeton‐Yanco, dans la Nouvelle Galles du Sud, le molinate a été appliqué sur du riz semé en lignes à des doses allant de 2,24 à 6,73 kg/ha et à des époques se situant depuis le présemis jusquà 36 jours après le semis. Les traitements ont été effectués sur sol sec et les applications en présemis ont été suivies d'une incorporation superficielle. Tous les autres traitements ont été suivies dans les 24 heures soit par une irrigation temporaire soit par une submersion permanente. Toutes les applications de molinate ont réduit les populations d'Echinochloa spp. mais les meilleurs rédultats ont été obtenus avec les traitements en post levée précoce. A cette époque d'application, la dose de 3,36 kg/ha a été habituelle‐ment aussi efficace que les doses supérieures. Le molinate n'a pas causé de dégâts sur le riz et les traitements n'ont provoqué des fluctuations du rendement que là où des infestations significatives d'Echinochloa spp étaient présentes. Bekämpfung von Echinochloa spp. in Reis mit Molinate in Neusüdwales In der Gegend von Leeton‐Yanco im südlichen Neusüd‐wales wurde in einer Reihe von Versuchen Molinate in ge‐drilltem Reis in Aufwandmengen von 2,24 bis 6,73 kg/ha eingesetzt. Behandelt wurde im Zeitraum von vor der Saat bis 36 Tage nach der Saat. Es wurde auf trockenen Boden gespritzt und die s Vorsaatbehandlungen wurden flach ein‐gearbeitet. Bei allen anderen Behandlungen folgte inner‐halb von 24 Stunden entweder ein Überfluten oder ein ständiges Überstauen. Sämtliche Behandlungen mit Molinate verminderten den Besatz an Echinochloa spp., die besten Bekämpfungserfolge wurden jedoch mit früher Vorauflaufspritzung erzielt. Zu diesem Behandlungszeitpunkt waren im Normalfall 3,36 kg/ha genau so wirksam wie höhere Aufwandmengen. Molinate verursachte keine Schäden beim Reis. Die Herbizi‐danwendung wirkte sich auf die Erträge aus, wenn starke Verunkrautung mit Echinochloa spp. vorhanden war.
