The study aimed to evaluate the effect of chitosan on controlling L. theobromae and R. stolonifer, fungi associated with postharvest diseases in papaya. In vitro and in vivo tests were conducted using different concentrations of chitosan and reference fungicide. The variables evaluated included the percentage of mycelial growth inhibition, the lesion area, and the disease severity. Chitosan concentrations between 0.75% and 1% showed high efficacy against both pathogens, with inhibition levels comparable to those of the synthetic fungicide, with no statistically significant differences in most treatments.
