Key Points
- Pre-emergence herbicide applications out performed post-emergence applications in this trial series
- No treatment gave perfect control. Heavy infestations (58 p/m2) were not controlled with single treatments. Sequences of herbicides looked promising and will be included in future research
- Topogard looked promising as a post emergence treatment, and will be tested in the coming season both pre and post-emergence
- A 35kg/ha yield depression was apparent in wheat for each single brome plant/m2 increase
- In wheat, none of the herbicide treatments employed had any detrimental effect on yield
- Barley was less tolerant of the range of herbicides used in these trials. Turonex appeared to be the safest on barley
