Charlotte Smith and guests discuss how farmers can best protect their crops from pests and diseases. She's joined by Liz Bowles, Associate Director of Farming and Land Use at The Soil Association, arable and beef farmer John Cherry who started the Groundswell Conference about No-till farming, and Sarah Mukherjee, Chief Executive of the Crop Protection Association. Together they consider what constitutes crop protection, the use of the herbicide Glyphosate, the impact of the ban of the insecticide Neonicotinoids and what the alternatives are to protect Oil Seed Rape, and what the Government should do with pesticide regulation after the UK leaves the European Union.
