War on brome: does crop-topping brome grass in cereals work? locations
Aims

To determine the effectiveness of controlling brome grass seed set with crop-topping short- season cereals sown at different times.

Key messages

Sowing early gave best crop competition with brome grass. Select a variety with high early vigour to suppress brome grass seed set. Select a variety with a short growing season when crop-topping brome.
