CPM finds out how the adjuvant Kantor can help fungicide delivery and maximise its performance in the leaf. Large molecules, like prothioconazole, can need extra help to get inside the plant. By Lucy de la Pasture There’s no getting away from the fact that it’s a challenging time in agronomy. Some disease pathogens are evolving at a much faster pace than the chemistry used to control them. It’s a situation made harder as the regulatory bar is set ever-higher, limiting the pool of active ingredients available to draw on. That means getting the most out of the available fungicides has never been more important, says Agrii regional technical adviser and Cambs grower David Felce. Some pesticides begin to break down as soon as they are combined with alkaline water in the tank. Although SDHI/azole mixtures are still giving good field control of septoria, monitoring data shows there’s been a further shift in the sensitivity of septoria to SDHI and azole chemistry. But there are things we can do to optimise spray delivery and help counter this move towards resistance by getting the…
