First Report of Pleurostoma richardsiae Causing Canker and Dieback of Avocado Trees in Mexico
Abstract
ABSTRACT In 2020, avocado trees ( Persea americana var. drymifolia ) showing symptoms of branch shoot dieback and cankers were found in commercial orchards in northern Nuevo Leon, Mexico. Fungal isolates obtained from symptomatic tissues were identified on the basis of morphology and multilocus phylogeny (ITS, EF1‐α, TUB2 and SSU). Pathogenicity was confirmed by inoculation on healthy branches of 7‐year‐old avocado trees. To our knowledge, this is the first report of Pleurostoma richardsiae causing canker and dieback in avocado trees.
