Herbicide tolerance of lupin varieties - Wongan Hills

To identify herbicide sensitivities of new lupin varieties with the view to reduce their yield losses due to herbicide damage. Mandelup was included as a standard variety for comparison in the trial.Blue lupins are problematic in narrow leave lupin production, especially in the Northern Agriculture Region of WA Wheatbelt and no herbicide is registered for their control in this crop. There were earlier reports that blue lupins could be controlled/suppressed with triclopyr (e.g. Garlon®) safely applied at pod setting on main stem of narrow leave lupins (Quinlan and Fleay, 2016). Two timing of application of Garlon® at 30 mL/ha were included in the trial to determine their safety on new narrow leafed lupin varieties.

本试验旨在明确新型羽扇豆（Lupin）品种对除草剂的敏感性，以降低其因除草剂药害引发的产量损失。本试验设置Mandelup作为对照标准品种，用于参试材料的比较分析。在窄叶羽扇豆（narrow leave lupin）种植体系中，蓝羽扇豆（blue lupins）会造成严重生产问题，尤其在西澳大利亚州（Western Australia, WA）小麦带北部农业区，目前尚无登记获批的除草剂可用于该作物田中的蓝羽扇豆防除。此前已有研究表明，在窄叶羽扇豆主茎结荚期施用三氯吡氧乙酸（triclopyr，如盖灌能®Garlon®），可安全实现对蓝羽扇豆的有效防除或抑制（Quinlan与Fleay，2016）。本试验设置两个施药时期，按30毫升/公顷的剂量施用盖灌能®Garlon®，以评估其对新型窄叶羽扇豆品种的安全性。
