The Australian canola industry was established in the 1970s and has expanded since that time, particularly in the last two decades. This review addresses the changes in farming practices since the year 2000 and the epidemiological and management consequences for blackleg, caused by the fungus Leptosphaeria maculans, the main disease impacting Brassica napus production. To help understand the change in production practices, a survey of over 100 growers and agronomists was conducted. Modern management practices include increased crop residue retention, frequency of canola in crop sequences, number of resistance genes in cultivars, use of hybrids and fungicides as well as earlier sowing and flowering times. While some of the changes identified in the survey and in this review increase the risk and severity of disease, including new symptoms like upper canopy infection, others provide novel strategies for control. Keeping these changes in mind, a set of research priorities towards long term sustainable management of blackleg disease are identified.

澳大利亚的双低油菜籽产业始建于1970年代，自那时以来一直在发展，特别是在最近的二十年中。这篇综述探讨了自2000年以来耕作方式的变化以及由真菌Leptosphaeria maculans引起的黑腿病的流行病学和管理后果，该病是影响甘蓝型油菜的主要疾病生产。为了帮助了解生产方式的变化，对100多个种植者和农艺师进行了调查。现代管理实践包括增加作物残渣保留量，双低油菜籽在作物序列中的频率，品种中抗性基因的数量，使用杂种和杀真菌剂以及更早的播种和开花时间。尽管在调查中和本次审查中发现的某些变化增加了疾病的风险和严重性，包括上冠层感染等新症状，但其他变化提供了新的控制策略。牢记这些变化，确定了一套长期可持续治疗黑脚病的研究重点。
