Tetraploid perennial ryegrass Mixture partner for better disease and stress tolerance
Superior in dry conditions
Ideal mixture partner (overseeding...)
Allround disease resistance
4n = Big seed - strong seedlings
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).
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!
Seed size and vigour
Seed of DOUBLE are at least 1,5 times heavier than diploid seed. It makes it easy to seed and gives stronger seedlings with faster establishment. Another argument for using DOUBLE in overseeding mixtures.
