Badger Research, Pesticides, Scottish Salmon

New research on tackling bovine TB: whether it's better to cull badgers or to increase the testing of cows. Charlotte Smith hears from Professor Matthew Evans of Queen Mary University of London whose computer modelling of the variables suggests that increased TB testing of cows could substantially reduce incidents of TB.

All this week Farming Today is looking into the use of pesticides. Today, Anna Hill hears about new developments in the manufacture of crop sprayers, that deliver the pesticides in the field.

As the salmon fishing season on the River Tay gets underway, Andrew Anderson of BBC Scotland tells Charlotte why anglers will be forced to return any they catch to the river following the introduction of a new statutory conservation policy.
