Mitigating herbicide resistant – investigating novel integrated weed management systems

The Challenge

Herbicide resistant weeds are increasing rapidly and limits the efficacy of herbicides as a management tool.

The Project

Combine chaff collection with cultural weed management strategies in a standard and innovating crop rotation. Cultural techniques include:

• High seeding rate
• Winter cereal crops
• Early-cut silage
• Perennial forage

The Results

Integrated weed management without herbicides is not effective enough to maintain yield and provide acceptable grassy weed control. However, incorporating integrated weed management and herbicide use can mitigate herbicide resistance risk and contributes to effective long-term weed control.

Grower Benefits

Implementing integrated weed management could allow growers to have effective long-term weed control while reducing risk of herbicide resistance.
