Herbicide resistance and other information on grass and broad-leaved weeds

This webpage provides links to a range of pdf versions of technical information leaflets and other publications written mainly by Dr Stephen Moss and colleagues and designed by the Visual Communications Unit at Rothamsted.

The information in these leaflets is based largely on research funded by Defra and HGCA and may be reproduced freely, and placed on websites, provided the source is fully acknowledged (e.g.  Black-grass: the potential for non-chemical control, by Stephen Moss & Peter Lutman (2013).  A Rothamsted technical publication, 4 pp.).

Limited quantities of printed versions of most of these publications are available on request.  For further information please contact Richard Hull, AgroEcology Department, Rothamsted Research.​
