Origin
Shark is bred by Mountain View Seeds (Oregon, USA).

 

Colour
Medium dark green turf type.

 

Characteristics of the cultivar
In NTEP putting green trials, Shark demonstrates perforamcne that exceeds existing standard varieties. It ranks in the top quality grouping for both soil and sand greens, even under a close mowing regime of less than 3 mm and under reduced fungicides application.

 

Performance on Greens

 


Shark delivers consistent results on any green composition even under mowing levels under 3.0 mm and reduced fungicides. Shark is rated no. 1 in summer density. It persists through summers’heat, humidity and disease stress. Shark provides anexcellent playing surface and is also able to suppress Poa annua due to an aggressive growth behaviour.

Sowing and maintenance
Seeding rates:
Shark is recommended to be used in pure stands and creeping bentgrass blends. For new courses Shark should be seeded at 5 - 7 gr/m2. For overseeding a sowing rate of 2 - 5 gr/m2 should be applied.

 

Mowing height
Shark requires frequent mowing and should be mowed at a low height. Recommended mowing heights are:
Greens     2.5 - 6 mm
Tees         6 - 10 mm
Fairways  10 - 12 mm


Watering
After seeding and establishing Shark prefers deep watering early in the morning.

Creeping bentgrass forms stolons which gives the specie an aggressive growth. It has a high susceptibility to turf diseases and it is in need of an intensive maintenance program to keep the turf quality on an acceptable level.
