Verticillium dahliae is a soil-borne phytopathogen and the causal agent of Verticillium wilt. It affects many agriculturally important crops around the world, including cotton. In Australia, the billion-dollar cotton industry is increasingly impacted by Verticillium wilt. Internationally it has been reported that the defoliating V. dahliae Vegetative Compatibility Group (VCG) 1A causes severe damage to cotton. In Australia however, the non-defoliating VCG2A is causing more severe damage to crops in fields than the defoliating VCG1A. This review examines the current research to understand the Australian V. dahliae situation, including current classification systems, genetic analyses and management strategies. It appears that virulence cannot be defined solely by VCG in Australian Verticillium dahliae isolates causing disease in cotton, and that the industry must continually adapt their practices in order to keep the disease under control.

黄萎病菌是土壤传播的植物病原体，是黄萎病的病原体。它影响了世界上许多重要的农业作物，包括棉花。在澳大利亚，数十亿美元的棉花产业越来越受到黄萎病的影响。国际上已经报道，落叶的大丽花植物相容性组（VCG）1A对棉花造成严重损害。但是，在澳大利亚，非落叶的VCG2A对田间作物造成的破坏比落叶的VCG1A更严重。这篇综述审查了当前的研究以了解澳大利亚V. dahliae情况，包括当前的分类系统，遗传分析和管理策略。似乎不能仅通过VCG来确定在棉花中引起疾病的澳大利亚黄萎病菌中的毒性，并且该行业必须不断调整其操作习惯以控制疾病。
