Quick Facts 

Keystone 2 was one of the top varieties in the 2004 NTEP Perennial Ryegrass trials. The most significant improvements of Keystone 2 over the original Keystone are its increased density, summer performance and disease resistance. Keystone 2 also has one of the finest leaf textures of any perennial ryegrass variety.

 

Keystone 2 does well under fairway and athletic field managements. An excellent resistance to Crown Rust and cool season Brown Patch reduces the need for fungicide applications. Early spring green-up means denser turf earier in the year, which can be an important advantage for sports fields and golf courses.
