The invention relates to a method for controlling banana wilt. The method comprises the steps of: spraying stems and roots with nutrient solution containing 0.05-0.3mg / L of naphthylacetic acid, 0.2-0.3% of borax solution and 2-6% of MgSO4 for 600-800ml / plant, and after yellow leaves become green, spraying the nutrient solution for 300-500ml / plant and 2-3 times at every 8-12 days; after the disease is improved, spraying the stems and the roots with nutrient solution containing 0.2-0.3% of borax solution and 2-6% of MgSO4 for 300-500ml / plant and 5-8 times at every 15-20 days. In order to control the disease after 2-3 years, magnesium fertilizers and boric fertilizers can also be applied for soil of each banana plant. The method has the advantages that the banana wilt can be effectively controlled according to the internal cause of the banana wilt, and the diseased leaves become green in a faster manner, so that the yield is increased and the disease can be continuously controlled for 2-3 years.
