Theory to Field – Slowing sensitivity shifts


Written by cpm

Download PDF Septoria is a bit of a shape-shifter when it comes to single-site fungicides. Minimising selection pressure and maximising control using both cultural and chemical strategies is the focus of two major AHDB projects. CPM reports their findings. It’s really difficult to look after MoA when you’re down to the last two standing. By Lucy de la Pasture The concept of pathogen mutations and the possibility of vaccine escape has been perfectly illustrated during the COVID-19 pandemic. In the same way Zymoseptoria tritici in wheat crops has become adept at finding ways to avoid the main groups of fungicides used to control the disease epidemic. Shifts in sensitivity to azole and SDHI chemistry are independently monitored by AHDB with the help of plant pathologists at Rothamsted Research and NIAB, and the results were reported during Agronomy Week last December as part of the fungicide performance studies. Although 2020 was generally an easy year for obtaining septoria control, it’s clear that septoria is continuing to evolve resistance. Catherine Harries, crop protection scientist at AHDB, says the fungicide performance work is backed by two significant projects which are seeking to find ways of slowing the evolution of resistance in the field.…

Hello, I’m Janet Hughes. I’m the Programme Director for the Future Farming and Countryside Programme in Defra – the programme that’s phasing out the Common Agricultural Policy and introducing new schemes and services for farmers.

Today (20 September) between 7pm-8pm, I and some of my colleagues will be answering your questions about our work including the Sustainable Farming Incentive, Farming in Protected Landscapes, and our test and trials.

We’ll try to answer at least 15 of your top voted questions, so please vote on the questions you’d most like me to answer.

You can read more about our Future Farming policy on our blog.

I’ve answered some of your questions previously: you can watch the videos on...
