The Food Research Collaboration has produced a briefing paper on pesticides policy after Brexit: Pesticides at a crossroads
It is noted, 'With Brexit looming, there is an opportunity for the UK to reshape its relationship with pesticides. It could choose to mirror or even surpass the standards of EU pesticide rules. On the other hand, it could bow to the pro-pesticide lobby and use Brexit as an opportunity to deregulate. This would allow a greater variety and larger quantity of harmful pesticides to be used, thereby putting the environment and the public’s health at risk.'
Among the recommendations are that the UK should maintain the EU’s hazard-based approach (rather than revert to a risk-based approach) to pesticide regulation and introduce a clear, quantitative target for reducing the overall use of pesticides in agriculture. A new government body should be created to support Integrated Pest Management (IPM) techniques. A pesticide tax should be introduced to drive reductions in pesticide use and fund research, development and innovation.
Farmers are, of course, concerned about the removal of active substances they see as essential to plant protection.
