Fight against stress
Tetraploids have long been known to show better stress and disease tolerance compared to diploids. Now these advantages are also available in a turf grass variety: DOUBLE. In particular in dry conditions DOUBLE outperforms diploids. DOUBLE is one of the varieties in our 4TURF brand (ask for specific brochure).
Disease resistance
Improved disease resistance is observed for rusts, Fusarium and Drechslera. After the very hard winter 2010/11 we had an excellent proof of the extremely high Fusarium resistance of Double.
Perfect mixture partner
As DOUBLE is less dense than top-quality diploids it makes it easier for Poa pratensis to establish. When combined with diploid perennial ryegrass a perfect overseeding mix is obtained. In mixtures with tall fescue the larger leaves of DOUBLE compared to diploids leads to a more homogeneous aspect.
Improved salt tolerance
DOUBLE has better salt tolerance than most diploids. Have DOUBLE in mind when establishing new turf areas!
