Abstract

First report of Neoscytalidium novaehollandiae associated with stem canker and branch dieback of almond trees.

Abstract

In 2019, a new disease of stem canker with branches dieback was observed in several commercial orchards in Diyarbakır province, Turkey. The pathogen was identified as Neoscytalidium novaehollandiae based on morphological characteristics and phylogenetic analysis of both internal transcribed spacer and transcription elongation factor 1-α regions. Koch's postulates were confirmed by successful reisolation of N. novaehollandiae only from plants inoculated with the pathogen. This is thought to be the first report of N. novaehollandiae causing stem canker of almond trees.
