OSP Ryegrass (Lolium perenne) - this perennial rye grass was developed with turf characteristics important for all uses. In addition, this rye grasshas superior seed quality, with a “Poa–free” tag based on extended seed testing so you are not planting your problems. The cultivars used exhibit rapid establishment, stress and disease tolerance, cool weather active growth, wear tolerance and recovery. They demonstrated high overall performance under various maintenance levels ranging from golf course fairways to residential lawns.

The range of performance of OSP ryegrass make it ideal for all perennial ryegrass uses. The components of this rye grass blend have been selected for excellent traffic tolerance which makes it superior for use on sports fields, as well as parks. The high summer performance due to its drought and stress tolerance make it ideal for permanent turf. Yet OSP rye grass has also shown excellent performance as a grass for overseeding bermuda grass with superior winter growth. Excellent germination and growth with saline water enable this rye grass seed blend to be used in marginal sites.

Disease Resistance: The cultivars in this rye grass blend exhibit high levels of Gray Leaf Spot resistance and are also resistant to many other important turf diseases, including: Crown Rust, Winter Net Blotch, Dollar Spot, Red Thread and Brown Patch. The broad genetic base insures high resistance against a broad range of diseases for consistent performance.

Endophyte-Enhanced: OSP rye grass seed contains high levels of viable endophytes. This provides resistance to a large number of surface and crown feeding insects including billbugs, sod webworms, chinch bugs and armyworms. The presence of endophytes also contributes to increased stress tolerance with better summer survival and enhanced fall recovery.
