Fusarium oxysporum f. sp. cubense (Foc) causes Fusarium wilt in banana (Musa AAA). Foc Race 1 devastated the subgroup Gros Michel during the first half of the twentieth century. The Gros Michel was largely replaced by the resistant subgroup Cavendish in the 1950s. However, in the 1980s, Foc Tropical Race 4 started to spread affecting Cavendish bananas. No proper control measures have been found to deal with the disease. This paper re-takes an important research line from the 1950s to evaluate the potential of soil management for Fusarium wilt management. The role of soil properties on Fusarium wilt in bananas was studied in two greenhouse experiments. It was evaluated whether the influence of two main soil properties (pH and N) on Fusarium wilt is similar for Race 1 and Tropical Race 4. Two soil pH levels (lower than 5.2 and higher than 6.0) respectively ensured through acidification and liming; and three levels of N (ammonium nitrate, 33.5% N) weekly doses (low:0 N g, medium: 0.08 N g and high: 0.25 N g per plant) were achieved. The first experiment in Costa Rica confirmed the earlier results about the influence of soil pH and nitrogen on Fusarium wilt (Race 1) on Gros Michel bananas. The second experiment in The Netherlands evaluated the influence of pH and N on interactions between Foc (both Race 1 and Tropical Race 4) and Cavendish bananas. Results in both experiments showed that soil pH affected crop development and the disease. Besides, the interaction of the lower pH x the higher N accelerated the infection and reduced plant development. As such, the results showed that soil management has the potential to reduce the impacts of Fusarium wilt while dealing with Race 1 and Tropical Race 4 although it requires confirmation and further evaluation under field conditions.

尖孢镰刀菌f。sp。香蕉枯萎病(FOC)导致枯萎病在香蕉(芭蕉AAA)。Foc竞赛1在20世纪上半叶毁灭了Gros Michel小组。格罗斯·米歇尔(Gros Michel)在1950年代被抗拒的卡文迪许小团体所取代。然而,在1980年代,Foc Tropical Race 4开始传播,影响了卡文迪许香蕉。没有发现适当的控制措施来治疗这种疾病。本文重述了1950年代的一项重要研究路线,以评估土壤管理对枯萎病枯萎病防治的潜力。在两个温室试验中研究了土壤特性对香蕉枯萎病的作用。评价了种族1和热带种族4的两个主要土壤特性(pH和N)对镰刀菌枯萎的影响是否相似。通过酸化和石灰化分别确保了两个土壤的pH值(低于5.2和高于6.0)。每周施用三剂氮(硝酸铵,氮33.5%)(低:0 N g,中:0.08 N g,高:0.25 N g)。哥斯达黎加的第一个实验证实了土壤pH和氮对Gros Michel香蕉上枯萎病(Race 1)的影响的早期结果。荷兰的第二个实验评估了pH和N对Foc(第1种族和热带第4种族)与Cavendish香蕉之间的相互作用的影响。两个实验的结果均表明土壤pH值会影响作物的生长和病害。此外,较低的pH x较高的氮的相互作用加速了感染并减少了植物的发育。因此,
