Maximising Your Autumn Weed Control

As summer draws to a close, many growers are transitioning from planning to preparation – ensuring paddocks and machinery are ready to go when the opening rains arrive and sowing begins. Pre-plant weed control is a critical part of that preparation and having clarity and confidence in your pre-emergent strategy is essential.

Overwatch® Herbicide and Overwatch® eXL Granules deliver long-lasting pre-emergent control of annual ryegrass and other key weeds in wheat, barley, canola and select pulse crops. With a Group 13 mode of action, Overwatch® adds valuable diversity to resistance management strategies, supporting robust weed control programs.

The distinct bleaching symptomology provides a clear visual indication of activity in the paddock, giving growers confidence the product is working as intended. Available in both liquid and granule formulations, Overwatch® offers flexibility to suit different operational preferences and application systems.
