Aims:
To investigate the impact of row direction and row spacing on grass weed competition and ceral performance over three years.
Aims:
Controlling barley grass in upper EP farming systems is becoming a major issue for growers, due to the development of herbicide resistance and delayed weed emergence. Management options other than herbicides need to be considered to address the issue for long-term sustainability. One of the best bets for cultural control of barley grass in-crop … read more
