Legislated pesticide‐use restrictions or bans in a growing number of countries worldwide are forcing growers and land managers to reactively plan, develop or implement alternative pest management practices and even entire farming systems. While the rapidly rising incidence of multiple resistance in weed populations had already begun this transition in many agroregions, the future pace of change will undoubtedly accelerate. We outline possible weed management alternatives, based on workshop discussions among Australian weed scientists or practitioners and agronomists, of grain cropping scenarios in a herbicide‐limited world. Further, we conducted bioeconomic model scenarios of grain crop production in southern Australia without the use of non‐selective burndown or pre‐harvest herbicides. Effectively and profitably managing troublesome weeds in major agronomic field crops in a restricted herbicide environment will be challenging, but can be considered as an opportunity for significantly greater adoption of ecologically based weed management tactics, strategies and systems.

有限除草剂对大田作物生产的全球挑战：澳大利亚的观点

全世界越来越多的国家/地区已通过立法限制农药使用或禁令，迫使种植者和土地管理者做出反应性的计划，制定或实施替代性的害虫管理措施，甚至整个农作系统。尽管杂草种群中多重抗药性的迅速上升的趋势已经在许多农业地区开始了这种转变，但毫无疑问，未来的变化步伐将加快。我们根据除草剂有限的世界中谷物种植的情况，根据澳大利亚杂草科学家或从业者和农艺师之间的研讨会讨论，概述了可能的杂草管理替代方案。此外，我们在不使用非选择性燃尽或收获前除草剂的情况下，对澳大利亚南部谷物作物生产的生物经济模型进行了研究。
