Rice production is severely hampered by the bakanae disease (), formerly recognized as was called the species complex (FFSC) because it was later discovered that it had some separate species. The FFSC's constituents are also well recognized for producing phytohormones, which include auxins, cytokinin, and gibberellins (GAs). The normal symptoms of bakanae disease in rice are exacerbated by GAs. The members of the FFSC are responsible for the production of fumonisin (FUM), fusarins, fusaric acid, moniliformin, and beauvericin. These are harmful to both human and animal health. This disease is common around the world and causes significant yield losses. Numerous secondary metabolites, including the plant hormone gibberellin, which causes classic bakanae symptoms, are produced by . The strategies for managing bakanae, including the utilization of host resistance, chemical compounds, biocontrol agents, natural goods, and physical approaches, have been reviewed in this study. Bakanae disease is still not entirely preventable, despite the adoption of many different tactics that have been used to manage it. The benefits and drawbacks of these diverse approaches are discussed by the authors. The mechanisms of action of the main fungicides as well as the strategies for resistance to them are outlined. The information compiled in this study will contribute to a better understanding of the bakanae disease and the development of a more effective management plan for it.
水稻恶苗病严重阻碍了水稻生产，该病以前被认为是一个物种复合体（Fusarium fujikuroi species complex，FFSC），因为后来发现它包含一些独立的物种。FFSC的成员还因能产生植物激素而闻名，这些植物激素包括生长素、细胞分裂素和赤霉素（GAs）。赤霉素会加剧水稻恶苗病的常见症状。FFSC的成员还会产生伏马毒素（FUM）、镰刀菌素、镰刀菌酸、串珠镰刀菌素和白僵菌素。这些对人类和动物健康都有害。这种病害在世界各地都很常见，会导致严重的产量损失。 会产生大量次生代谢产物，包括导致典型恶苗病症状的植物激素赤霉素。本研究综述了防治恶苗病的策略，包括利用寄主抗性、化合物、生物防治剂、天然产物和物理方法。尽管采用了许多不同的防治策略，但恶苗病仍然无法完全预防。作者讨论了这些不同方法的优缺点。概述了主要杀菌剂的作用机制及其抗性策略。本研究收集的信息将有助于更好地了解恶苗病，并制定更有效的防治计划。
