Annual ryegrass resistance continues to challenge Australian growers, making informed herbicide decisions more critical than ever. This season, FMC is offering a unique opportunity to combine proven pre-emergent weed control with valuable resistance testing—at no extra cost.

From 1^st September to 30^th November 2026, growers who purchase a qualifying volume of Overwatch^® Herbicide and/or Overwatch^® eXL Granules in a single transaction will become eligible to receive a complimentary Herbicide Resistance Seed Test, valued at $695. Conducted by Plant Science Consulting (PSC), the test screens ryegrass samples against 14 different herbicides and herbicide mixtures including clethodim and glyphosate and the pre-em herbicides Overwatch^®, Sakura*, Trifluralin, Boxer Gold*, Avadex* and Luximax*.

“To make smart decisions about resistance management, growers need good data,” says Stuart McLaverty Senior Portfolio and Campaign Lead at FMC Australasia. “This incentive gives a grower access to professional testing without the usual cost barrier—and it’s paired with products that growers have already embedded in their weed control strategies targeting annual ryegrass.”

To qualify, a grower must purchase in a single transaction enough product to treat a minimum of 500 hectares. That’s either:

• 640 L Overwatch^® Herbicide, or
• 340 kg Overwatch^® eXL Granules, or
• A combination of both sufficient to meet the minimum 500 ha threshold.

After purchase, a grower would simply upload their tax invoice and enter the required details onto FMC’s dedicated landing page. A test kit will then be sent out, complete with sampling instructions and a unique identifier to ensure accurate tracking. A grower or their agronomists would then collect ryegrass panicles from the target paddock ideally prior to harvest and send them to PSC for analysis. Results will be communicated directly back to the grower before the end of July 2027.

“This is about helping growers understand what’s working in their paddocks—and what’s not,” McLaverty explains. “Resistance is evolving, and having clarity on herbicide efficacy is essential for long-term planning.”

The offer is limited to 250 test kits, so early participation is encouraged. While the purchase window closes on 30^th November, the landing page will remain open until 18^th December 2026 with all annual ryegrass seed samples to be submitted by 1st March 2027.

“Overwatch^® continues to deliver excellent pre-emergence weed control,” says McLaverty. “Now, with this added incentive, growers can take a proactive step toward managing resistance and protecting their productivity.”
