Abstract

In 2019, a new disease of stem canker with branches dieback was observed in several commercial orchards in Diyarbakir 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-alpha 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.
