Aims and objectives


 The combined objectives of the project were:

a) To study cross-reliance patterns and inheritance of herbicide resistance in black-grass in order to determine the risk of increase of resistance in the United Kingdom.

b) To determine the respsonse of several populations of resistant black-grass to a range of herbicides applied under stimulated field conditions, in order to confirm the relevance of resistance ratings derived from glasshouse tests to field conditions.
