MANAGING SELECT®-RESISTANT RYEGRASS IN CANOLA AND WHEAT locations
Aims

To investigate the impact of different herbicide strategies in RT-canola (Roundup & triazine tolerant) and wheat on the long-term control of Select-resistant ryegrass.

Key messages

The results have clearly shown that effective soil residual herbicides used in combination with timely applications of POST glyphosate in RT-canola can provide acceptable control of Group A resistant ryegrass. Ability to reduce seed set and seedbank replenishment in this initial phase of 2-year break is crucial to long-term management of ryegrass, particularly given that wheat is to follow and weed
control will rely on the few effective pre-emergent herbicides available.
