CLEEK

Top ranked for use on golf greens - Excellent disease tolerance

Top performance!

CLEEK is out of European breeding with a wide genetic background offering excellent green performance in Scandinavia and confirms the high level in STRI close mown trials.

Disease tolerance

One explanation for the top ranking in Scandinavian trials is certainly the good resistance to a range of diseases combined with density and fineness. CLEEK manages to keep a good winter colour and still maintain a good winter hardiness.

Adapted to greens and fairways

The STRI trials also perhaps very good performance for use on tees/fairways (trials cut 10-15 mm).

Salt tolerance

CLEEK turned out as one of the better in our salt tolerance trials (coastal areas, irrigation water with salinity...).

  • Top performance on greens in STRI (UK) and Scangreen network
  • High tolerance to several important diseases
  • Winter hardy and good winter colour
  • High performance for fairway use too
