Descripción:This crop has serious constraints with diseases, including those caused by bacteria, such as Dickeya sp. This research aimed to evaluate the effect of 4 resistance inductors and 3 doses in Chlorine Dioxide in handling watery rot of pseudo-stem (Dickeya sp.) in banana. Resistance inducers and their doses were Potassium Phosphite: 1.5 cm 3 .l -1 ; 3-Aminobutanoic Acid: 1.0 g.l -1 ; Methyl Jasmonate: 0.2 g.l -1 ; S-Methyl-Acibenzolar: 0.3 ml.l -1 , all by foliar application, while Chlorine Dioxide was injected into the pseudo-stem, in doses of 10, 20 and 30 mg.l -1 . The evaluated variables were: development of the disease, total biomass and quantification of the bacterium in the inoculated pseudo-stems. Applications of Chlorine Dioxide achieved a reduction of disease by 65.4, 91.99 and 61.5%, in addition to an inhibition of 100% of the pathogen, using 30 and 50 mg.l -1 doses. Meanwhile, the use of resistance inductors reduced up to 60.6% of the disease, but this effect failed to improve plant growth.
