In recent years, the frequency of its occurrence has increased year by year. In order to provide a scientific basis for thecontrol of this disease, an experiment was conducted to screeneffective pesticides to be used in pitaya production.The fungicidal activity of nine fungicides against pitayacanker was determined with the mycelial growth inhibition method.
