Mapping is often mentioned as a tool to plan black-grass control – but how do you turn maps into a practical action plan? This podcast will find out.

Dealing with black-grass is a learning process process and growers need to work out what strategy works best on their farm, in this podcast we hear from one farmer who's getting on top of some very difficult black-grass as well as a farm trial site where Bayer are demonstrating how control is possible.

Two of the most respected researchers involved in the study of black-grass talk about how resistance has become such a challenge and how growers can deal with it in the present.
