Glyphosate debate, Lamb prices, Farm safety among older workers

Charlotte Smith debates calls to limit the use of of the weedkiller glyphosate. Peter Melchett of the organic pressure group, the Soil Association, is calling for a UK ban on certain uses of the chemical - for example its use on wheat as a pre-harvest weedkiller. It follows a decision this week by the International Agency for Research on Cancer to classify the chemical as a 'probable carcinogen'. However the Crop Protection Association, which represents the chemical companies, says fears over its use are unfounded.

We hear from sheep farmers at the Great Yorkshire Show, who explain that they're affected by a price slump for lamb, complaining that not all retailers have passed this drop on to customers.

And farm safety: what's being done to encourage better practices among older farm workers.
