This research aims to identify Lasiodiplodia species linked to mango dieback and stem-end rot, and to evaluate their pathogenic effect on mango fruits.
Collected samples from 27 orchards in five states of Mexico exhibiting dieback and stem-end rot symptoms in mangoes.
Conducted phylogenetic analyses (ITS, tef1-α, tub2) on 87 Lasiodiplodia isolates using Maximum Likelihood and Bayesian Inference.
Performed pathogenicity tests on detached mango fruits using the mycelial plug inoculation method.
Identified eight Lasiodiplodia species associated with mango tissues, six of which are reported for the first time in Mexico.
L. laeliocattleyae and L. brasiliense demonstrated the highest aggressiveness in inducing necrotic lesions on mango fruits.
Pathogenicity of other strains was lower, affecting the severity of lesions.
