Shark (=Tigershark) is a next generation creeping bent variety with an aggressive growth habit and tight density.
- Dense uniform surface.
- Excellent drought and heat performance.
- Aggressive establishment.
- Improved disease tolerance.
- Top variety against Poa annua invasions.
Shark is bred by Mountain View Seeds (Oregon, USA).
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
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.
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
After seeding and establishing Shark prefers deep watering early in the morning.
