A Year of Plant Pathogens

11th August 2023 Plasmopara euphrasiae on Euphrasia sp. from Slievenacloy, Antrim. This is the first Irish record, though there are records from many years ago that can be reinterpreted as this species, which has since been split from the related species P. densa. More details in my blogpost here.

12th August 2020 Triphragmium ulmariae on Filipendula ulmaria in Ballymorran, Down. Fairly common at the right time of year.
