Demonstrating Ryegrass control strategies- An update locations
Aims

To demonstrate locally validated weed management strategies to assist growers improve control of ryegrass populations emerging in different environments, and where herbicide application alone fails.

Key messages

• Integrating a range of locally validated weed management strategies is important when tackling annual ryegrass
• Rotating crop types and chemistry are vital components of all weed and disease control strategies
• It is important to also consider nonchemical weed control strategies, due tow the increasing rates of herbicide resistance being seen in local ryegrass populations
• Seed testing indicated ryegrass resistance to Group 1 herbicides at the trial site.
