A late blight genotype that is resistant to a second fungicide mode of action continues to spread through Europe, meaning British potato growers will need to take extra care when planning control strategies next year, as Adam Clarke reports for Farmers Weekly.
The Fight Against Blight (FAB) monitoring initiative, which looks for genetic changes in the late blight population and its sensitivity to key fungicides, delivered its latest results at the 2023 British Potato event (BP2023).
There is little change in the British population this year, with 36_A2 (51%) and 6_A1 (34%) still dominating the 830 genotypes isolated from samples sent to the James Hutton Institute (JHI) in Dundee for testing.
