Better sward quality after stress
In southern and continental areas in Europe 4TURF shows better recovery from both drought and heat stress as well as winter stress. Thus it outperforms ordinary diploid ryegrasses.

Rapid installation
4TURF seeds are 1.5 times bigger than normal turf grasses. 4TURF produces stronger seedlings with faster establishment, resulting in less chances for the establishment of weeds. Thus 4TURF is the perfect oversowing choice for perennial ryegrass applications. 4TURF is very well suited for oversowing Bermuda in the transition zone resulting in a fast establishment and excellent turf quality but no more clippings.

Johnsons 4TURF Disease ResistanceBetter disease resistance and stress tolerance
4TURF has an improved disease resistance, both under warm and cold conditions. In DLF trials from Scandinavia to the Mediterranean it has proven to be more resistant against F.E. rust, Fusarium, Elminthosporium, Drechslera, and Red Thread. It is very well suited for extensive management conditions.

Good wear tolerance
In German trials 4TURF varieties Double and Tetragreen are rated 8 sport/wear conditions using a 1-9 score. The shear strength is enhanced due to the deeper root systems.
