Clarke, speaking at the ADAS/Syngenta Potato Conference in Peterborough, said that because potato growers faced a possible 15 per cent reduction in profitability when the laws change, they needed to address its impact by making the most of advances in application technology, prediction models and plant breeding.
"Strong stewardship of products will be an essential element of coping with this pesticide law change," he said. "Increasingly, we are seeing the way products are advocated for use changing with stewardship programmes - primarily for better application, improved resistance management and protecting the environment."
He continued: "It is absolutely vital that everybody participates and complies with these stewardship initiatives as we move forward. Generally, potato or vegetable growers have been very actively engaged with these, but it will become even more important in the future."
