Integrated weed management locations

To investigate weed suppression through cultural management practices and various crops and cultivars.

Key messages

These trials demonstrate that certain crop species and cultivars such as barley, oats and grazing wheat, can
suppress weeds effectively at standard establishment rates. This may be due to their ability to compete
effectively with weeds for valuable resources, or their potential to exhibit allelopathic effects associated either
with the crop or remaining residues following harvest.
