SR 4650
SR 4650 Perennial Ryegrass (PSRX-3701) (Lolium perenne) is an attractive, leafy, endophyte-enhanced ryegrass that has the highest level of Gray Leaf Spot resistance of any perennial ryegrass. It has demonstrated high overall perfor- mance under various maintenance levels ranging from golf course fairways to residential lawns. Early development of spreading rhizomes gives this variety increased density when used for permanent turf, along with improved wear tolerance and recovery
