The lack of control options was raised as a concern at an NGN meeting in Goondiwindi. Herbicides have been the dominant form of control for Phalaris; however, resistance has developed in populations of Phalaris to some Group 1 and 2 herbicides. To improve control of resistant populations and prevent further spread of resistance, growers are in need of more options for control. A better knowledge of the efficacy of pre- and post-emergent herbicides can help growers when designing their weed management strategy. Additionally, improving crop competition through increasing crop density has been shown as effective for controlling Phalaris. Increasing crop density alongside herbicide application may give growers good control of Phalaris while limiting the risk of resistance development.
This investment will assess the effectiveness of pre- and post-emergent herbicides on Phalaris control in field conditions alongside the impact of improved crop competition to provide growers with a non-chemical control option.
NGN - Development of management strategies for controlling Phalaris in Northern NSW and Southern QLD
Phalaris is a winter annual grass which was ranked as the 9th most prevalent weed in the Northern region in 2016. The current impact of this weed is likely much greater, as in recent years Phalaris has increasingly become a problem weed in the Northern region.
