SR 4600 TURF RYEGRASS
Superior Gray Leaf Spot, Crown Rust and Red Thread resistance results in less fungicide use.
Excellent wear tolerance and improved recovery from injury.
Improved Summer stress tolerance and Winter active growth.
High seedling vigor for fast emergence and establishment High resistance to Billbugs and other insects due to high endophyte levels.
Ideal for use on golf course fairways and tees, sports turf fields, home lawns and use as a winter over seed.
Superior Gray Leaf Spot resistance.
Excellent wear tolerance due to spreading growth habit.
Fine leaf texture and vivid, dark green color
SR 4600 is a new perennial ryegrass that is the result of years of cooperative research between Rutgers University and Seed Research of Oregon. SR 4600 traces its origins back to 33 clones selected at Rutgers University for improved Gray Leaf Spot resistance, very high turf quality, improved color, summer stress tolerance, and a spreading growth habit. Progeny of those clones were sent to Seed Research of Oregon’s research facility where further screening was completed for higher seed yield, colour, and improved stress and disease resistance in the production environment. SR 4600 has a demonstrated an improved Winter active growth profile which provides a marked advancement over other varieties. SR 4600’s dark green color and high stress tolerances makes it ideal for a variety of professional turf applications. It blends well with other perennial ryegrasses for golf course fairways, sports fields, sod production and home lawns. It also mixes well with Kentucky bluegrass and fine fescues. When blended with other perennial ryegrasses or mixed with Poa trivialis or fine fescue SR 4600 makes an ideal Winter over seed on permanent bermuda grass turf.
