Manta LE is fast to establish, has robust winter production, and an extended period of productivity. In the northern regions in New Zealand, Manta LE is anticipated to endure through a second winter, while in milder climates, it demonstrates significant persistence for an Italian ryegrass. Manta LE is suitable for grazing with all stock types.

Manta with AR37 endophyte is a fast establishing highly productive variety which is a recent addition to the AR37 endophyte line up. Manta AR37 stands out as an excellent choice for undersowing into damaged pastures, leveraging its quick establishment and robust growth offering a dependable solution for such scenarios.

Performance Data

Manta is a new generation of Italian ryegrass that has undergone significant selection in the upper North Island and includes genetics from short term ryegrass ecotypes (some possibly hybrids) from Northland. Alongside this northern New Zealand ecotype material, Manta has parents from a core pool of successful New Zealand Italian cultivars as well as genetics from Spain making it a diverse and exciting addition to Agricom’s ryegrass portfolio. Manta was originally bred with AR37 endophyte however it has first been commercialised in Australia as a fast starting Italian without endophyte.  

Seasonally Manta demonstrates very strong establishment and winter growth, peaking in performance through late September until the end of its first summer. Manta has a particularly strong second winter growth habit which is productive and highly visual. With its strong establishment, Manta is ideal for undersowing into thinning or run-out pastures.
