Abstract

First report of the fungus Gnomoniopsis smithogilvyi causing cankers on sweet chestnut (Castanea sativa) in Ireland.

Abstract

In autumn 2020, cankers and branch dieback were found in a 5-year-old gene bank plantation of Castanea sativa in Wicklow, Irish Republic. The planting material had been imported as grafted saplings from the UK. Isolations were made from the cankers and the causal organism was identified as Gnomoniopsis smithogilvyi based on morphological and ITS sequence analyses. This is thought to be the first report of G. smithogilvyi causing cankers on C. sativa in the Irish Republic.
