Lolium perenne
SR 4750
SR 4750 Perennial Ryegrass is a top-tier turfgrass variety known for its superior disease resistance and exceptional turf quality under all management levels. With strong resistance to Gray Leaf Spot, Red Thread, Brown Patch, and Crown and Stem Rust, SR 4750 ensures a healthier, more resilient lawn, sports field, or golf course. Its very dark green color, fine leaf texture, and dense growth create a premium appearance while maintaining excellent playability. This variety establishes rapidly in just 7-10 days, making it a reliable choice for quick turf coverage, overseeding, or sod production.
Designed for durability and versatility, SR 4750 excels in high-traffic areas thanks to its superior wear tolerance and rapid recovery. Its salt tolerance makes it particularly well-suited for roadside plantings and irrigation with effluent water, ensuring adaptability in challenging environments. Whether used alone or blended with Kentucky bluegrass for year-round quality and sod strength, SR 4750 provides a dense, resilient, and visually striking turf.
