Farmers across the country say they're concerned by the withdrawal of a product used to control bracken. This year Asulox was not approved for use in Wales, Scotland and Northern Ireland and allowed only under emergency authorisation in England. Government rules mean the herbicide would need additional health and safety testing work to be allowed for future use, and the company that makes it has decided not to do that. So what does the future hold? We hear from the Green Farm Collective - this year's winners of the Farming for the Future category of the BBC Food and Farming Awards. And Anna Hill visits a massive machinery sale in Cambridgeshire, joining collectors and enthusiasts ready to spend thousands on rural ephemera.
