Abstract : Since 2003, adult mango trees (cultivars Criollo and Kent) located in Piura Province developed symptoms of dieback characterized by the death of twigs and branches in the tree canopy. Additional disease symptoms involved darkened, elongated lesions on the peduncle, causing an early maturation of the fruit, and in advanced symptoms, stem-end rot of fruits. Symptoms were frequent in the spring months (September to November) when the lesions expand rapidly. The pathogen was identified as Neofusicoccum parvum. This is thought to be the first report of N. parvum affecting mango in Peru.
