A meaty AHDB-led project aims to find out the best way to keep the handbrake on this process. CPM finds out more. We can have the freedom to mix or alternate fungicides, knowing that either strategy will help reduce selection pressure. By Adam Clarke Back in 2017, there was growing concern about septoria insensitivity to SDHIs, with the fungicide group’s performance wobbling against a backdrop of continued decline in DMI (azole) efficacy against the disease. These factors were prompting leading crop pathologists to question whether growers should be applying two SDHIs in a season, which had become standard practice, and the routine use of azole-based T0s was also thrown into doubt. Adding to sweaty palms – at least amongst the research community – was the realisation the approval of multi-site fungicide chlorothalonil, so long the lynchpin of septoria control and anti-resistance strategies, was on borrowed time. This would potentially leave growers with just two main fungicide groups for controlling septoria, both acting on a single target site so more prone to sensitivity shifts in target populations.
