New field lab: Controlling bromes and preventing herbicide resistance

Published on


Brome weeds are wide-spread across all cereal growing areas of the UK and are becoming increasingly problematic and hard to control.

ADAS weed scientist, Laura Davies, will be holding a kick-off meeting for a new Innovative farmer's field lab on controlling brome and preventing herbicide resistance on 19th June at our Rosemaund site near Hereford.

New field lab: Controlling bromes and preventing herbicide resistance

This meeting is for farmers and advisors who want to look at:

  • Identifying methods that help slow or prevent herbicide resistance evolution of brome grasses
  • Finding out what controls work best in the field

Results from ADAS’s 2017 on-line survey showed that the incidence of brome weeds are increasing in UK arable farming. Although sterile brome is still the most wide-spread species, great and rye brome populations are also becoming more common. Along with meadow bromes, these weeds are all getting harder to control. However, information on brome species is lacking; particularly details of when they emerge in the field, and what cultivation types/depths and timings are most effective at controlling the weeds.

There is also concern over the development of herbicide resistance in UK bromes, with ALS and ACCase herbicide resistant populations already present in mainland Europe, and UK sterile brome populations identified as being in the process of developing glyphosate resistance. Preventing resistance development is typically only half of the cost of controlling resistance once it has appeared and it is vital resistance prevention strategies are tested before bromes become as problematic as black-grass.

This group aims to look at the most practical in-field methods to control bromes and help prevent herbicide resistance.

Lunch, teas, and coffees will be provided.

Sign up here to book your FREE place for 10am 19th June.


This research is part of the ADAS project ‘Investigating the distribution and presence, and potential for herbicide resistance of UK brome species in arable farming’, funded by AHDB.
