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.

This two page leaflet highlights the key traits for identifying the two main species of wild-oats which are weeds of arable crops in the UK.
An eight page leaflet produced by the UK Weed Resistance Action Group (WRAG) and the AHDB providing guidelines for minimising the risk of glyphosate resistance in the UK,
A two page summary of the guidelines for minimising the risk of glyphosate resistance in the UK, produced by the UK Weed Resistance Action Group (WRAG) and the AHDB.
This four page leaflet highlights the key traits for identifying the five main species of bromes which are weeds of arable crops in the UK.
This two page leaflet highlights the threat posed by herbicide resistant weeds in non-agricultural situations (e.g. public places, industrial sites, railways etc).
A 24 page booklet on weed biology and management, incorporating the latest UK Weed Resistance Action Group (WRAG) Guidelines on Herbicide-resistance Prevention and Management (updated spring 2014). Includes useful further information on other weed-related HGCA Guides, Topic sheets, Information sheets and Project Reports.
This four page leaflet was written by Stephen Moss (Rothamsted), Lynn Tatnell (ADAS) and Gordon Anderson-Taylor (Bayer) on behalf of the UK Weed Resistance Action Group (WRAG).
This four page leaflet summarises over 35 years’ research on black-grass, including its occurrence, biology, effect on yields, herbicide resistance and integrated weed management.
This is a four page summary which quantifies the efficacy of a range of non-chemical methods for control of black-grass.
The Rothamsted Rapid Resistance Test for detecting herbicide-resistance in black-grass, wild-oats and Italian rye-grass, 1999
This 16 page booklet plus 2 page summary provides a detailed protocol for detecting herbicide resistance in annual grass-weeds using a Petri-dish germination assay.
Detecting herbicide resistance: Guidelines for conducting diagnostic tests and interpreting results, 1999
This 12 page publication was written by Stephen Moss (Rothamsted) on behalf of the Herbicide Resistance Action Committee (HRAC) and gives additional information on how to identify herbicide-resistant weeds both in the field and by using diagnostic tests.
The Rothamsted Rapid Resistance Test for ALS inhibiting herbicides: Black-grass (Alopecurus myosuroides), 2007
This seven page protocol for a Petri-dish germination test can be used as an indicator of ALS target site resistance using herbicides such as sulfometuron (‘Oust’) and mesosulfuron+iodosulfuron (‘Atlantis WG’) on seed samples.
