Download PDF Don’t allow the last few years of low septoria pressure to lull you into a false sense of security – it’s evolved into a greater threat than ever. CPM gleans expert advice on the pathogen and how to use new chemistry to keep it in check. Septoria is an odd-ball pathogen. By Tom Allen-Stevens Last season was tough for wheat growers. It started with very low septoria pressure and PCR testing revealed a very low threat from the disease right up until flag leaves emerged. Then the weather changed, it turned warm and wet, and this showed that if you get the right conditions, septoria will rip through your wheat crop, if left exposed, notes NIAB crop protection and agronomy specialist Dr Aoife O’Driscoll. It’s a challenging pathogen, and many varieties with supposedly good resistance didn’t perform as they should, she adds. This year new chemistry may help growers address the threat, though, says Mike Ashworth, cereal fungicide product manager with Corteva Agriscience. But resistance management will be crucial to preserve efficacy against this predatory pathogen. Here they describe the challenges and best tactics for the season. Why is septoria control challenging? In comparison with most cereal diseases,…
