A new ryegrass endophyte is making waves in the Australian dairy sector, offering high performance ryegrasses at a price point that makes sense for farmers. Cropmark Seeds CM142 endophyte is emerging as a cost-effective solution for those seeking robust pastures with similar benefits as other advanced ryegrass endophytes in the market.

Introduced in early 2025 with Australian conditions in mind, CM142 endophyte features an exclusive genetic background and optimised alkaloid levels to deliver a balance of performance, persistence, and animal safety. Its introduction with brand new ryegrasses, such as Stampede diploid perennial (see link) ensures farmers can achieve productive endophytic pastures without overextending their annual pasture budgets.

Peter Notman of Notman Pasture Seeds highlights the significance of CM142 for local farmers.

“Stampede CM142 perennial and future releases with this endophyte in tetraploid perennials, hybrids and italian ryegrasses provide a cost-effective option that performs as well as other high-endophyte products in the market” says Mr Notman.

“Having worked with AR37 for the past decade, we’ve gained a deep understanding of how to integrate advanced endophytes into diverse pasture systems” says Mr Notman.

‘Whether its the sandy rises of Nirranda, the heavy flats of Foster, irrigation country of Maffra, and many places in-between, we think there is a real fit for these new grasses and endophytes”.

“Our experience ensures we can confidently recommend CM142 as part of a tailored approach that meets the unique needs of many Australian dairy farmers. Endophytes aren’t just about science—they’re about knowing how to place them effectively on the farm. I think our team are well versed on how to help to this”

One of CM142’s key benefits is its reduced levels of epoxy-janthitrem alkaloids, which have been shown in trials to significantly lower the risk of ryegrass staggers. This feature supports the likes of Stampede animal health during the challenging summer months, significantly reducing the risk of ryegrass staggers compared with standard endophytes ryegrasses and ensuring livestock remain more productive and stable in hotter conditions.

Additionally, CM142 is helping to enhance pasture persistence and yields, making it an ideal solution for farmers facing the challenges of variable conditions and the ever-rising input costs. Multiple farmers have trailed the product in 2024 with great feedback so far.

Peter emphasises its practicality: “Farmers I’ve chatted to lately are looking for solutions that are cost effective, more productive, persistent. CM142 in these two new grasses checks all those boxes while being mindful of their bottom line.”
