This study aimed to determine the effect of silicon (Si) in reducing the symptoms of Fusarium wilt, caused by Fusarium oxysporum f. sp. cubense (Foc), on banana plants. Banana seedlings of Grand Nain (resistant) and Mac¸a? (susceptible) were grown in plastic trays amended with 0 (Si) or 0.39 g Si (+Si) per kg of soil and inoculated with Foc at 60 days after transplanting. The Si concentration in the roots and rhizome-pseudostem significantly increased by 30.26 and 58.82%, respectively, for the +Si treatment compared with Si treatment. The Si concentration in the roots and rhizome-pseudostem of Grand Nain plants was, respectively, 11.57 and 37.04% greater than that found in Maçã . The +Si plants showed a reduction of 12.37, 49.81, 51.87 and 20.39%, respectively, for the area under reflex leaf symptoms progress curve, the area under root symptoms progress curve, the area under disease progress curve and the area under asymptomatic fungal colonization of tissue progress curve compared with -Si plants. The area under darkening of rhizome-pseudostem progress curve (AUDRPPC) of Maçã significantly increased by 15.98% for the Si treatment in comparison with the +Si treatment. For the +Si treatment, the UDRPPC of the plants from the Maçã cultivar significantly decreased by 20.59% in comparison with the plants from the Grand Nain cultivar. The area under relative lesion length progress curve (AURLLPC) of the plants from the Maçã cultivar significantly decreased by 41.54% for the +Si treatment in comparison with the -Si treatment. There was no significant difference between the -Si and +Si treatments in the AUDRPPC and AURLLPC of Grand Nain. For the +Si treatment, the AURLLPC of Grand Nain significantly decreased by 9.23% in comparison with Maçã . There was no significant difference between the Grand Nain and Macã for the AUDRPPC and AURLLPC in the Si treatment. The findings of this study show that supplying Si to banana plants, especially to a susceptible cultivar to Foc, had a great potential in reducing the intensity of Fusarium wilt and may play a key role in disease management when banana plants are cultivated in Si-deficient soils infested by this pathogen.
