TETRAGAME

Tetraploid with very good disease tolerance !

Overall high disease tolerance

Our range of tetraploid perennial ryegrass varieties are known for high and large disease tolerance. TETRAGAME is no exception, with excellent resistance to red thread disease, Microdochium patch, Drechslera leaf spot and rusts.

Leaf colour, fineness and density

TETRAGAME has a nice medium-dark green appearance. With density and fineness comparable to the average of diploids, it is an excellent choice in mixtures for sport fields where the strong plants will contribute to the overall strength of the turf.

Mixtures

TETRAGAME is also a good choise for tall fescue dominated mixtures as it competes less than diploids during the crucial months of establishment.
