香蕉（Musa spp.）是热带、亚热带地区重要的经济作物和粮食作物。镰刀菌枯萎病，也被称为巴拿马病，是由尖孢镰刀菌f。sp. cubense（Foc.）它是该作物最具破坏性的病害之一，并且具有相对广泛的宿主范围。其最大的影响是早期的“格罗斯米歇尔”为基础的出口贸易。卡文迪什亚组的抗性品种被用来取代“格罗斯米歇尔”，但现在屈服于病原体的一个新变种，热带小种4（TR4）。虽然TR4只在东半球发现，但它威胁到卡文迪什品种的全球出口和小农生产。这种疾病的管理在很大程度上局限于从非疫区排除病原体，并在Foc建立的地方使用抗性品种。这种作物的常年生产和这种疾病的多环性阻碍了其他管理策略的发展。对这些病害的一年生或短命寄主有效的措施通常对香蕉枯萎病无效。尽管有大量关于生物、化学和文化方面的积极文献，但没有有效的措施。需要对这些措施进行严格的评价和现实的期望。对这种疾病需要更好的抵抗力，特别是由TR4引起的疾病。(C)2015爱思唯尔有限公司版权所有。
Banana (Musa spp.) is an important cash and food crop in the tropics and subtropics. Fusarium wilt, which is also known as Panama disease, is caused by Fusarium oxysporum f. sp. cubense (Foc). It is one of the most destructive diseases of this crop, and has a relatively wide host range. Its greatest impact was on the early 'Gros Michel'-based export trades. Resistant cultivars of the Cavendish subgroup were used to replace 'Gros Michel,' but are now succumbing to a new variant of the pathogen, tropical race 4 (TR4). Although TR4 is only found in the Eastern Hemisphere, it threatens global export and small-holder production of the Cavendish cultivars. Management of this disease is largely restricted to excluding the pathogen from non-infested areas and the use of resistant cultivars where Foc is established. The perennial production of this crop and the polycyclic nature of this disease hinder the development of other management strategies. Measures that are effective against annual or short-lived hosts of these diseases are usually ineffective against Fusarium wilt of banana. Effective biological, chemical and cultural measures are not available, despite a substantial, positive literature on these topics. Critical evaluations of, and realistic expectations for, these measures are needed. Better resistance is needed to this disease, especially that that is caused by TR4. (C) 2015 Elsevier Ltd.
