Black grass, African wildlife, Fell walking

Farmers are facing a menace to their crops which is spreading across the country. Black Grass, which can severely reduce crop yields, and has already affected farmers in eastern England, has developed resistance to a range of herbicides. Farming Today reports on the fight to beat this hardy weed. We hear the latest report from our reporter on safari in Africa and why you should wear the right clothes when walking, even when it's hot.
