Lolium perenne (4N)

Tetrasport

Tetrasport

Tetrasport (DLFPS-238/3014) tetraploid perennial ryegrass (Lolium perenne) is part of the 4turf® ryegrass program for tough turf. It was developed to be quick establishing, even in cold temperatures, strong and deep rooting and tolerant of many stresses. Tetrasport is better able to withstand drought, cold, disease and recover better from wear. The larger seeds contain more reserves for stronger and faster establishment. It has a deeper crown and superior rooting to help with drought resistance and recovery. Tetrasport has shown excellent traffic tolerance and recovery in the 2016 NTEP. Tetrasport establishes faster and gives you thick green turf throughout the year. It is perfect for repairing damage or as part of a blend for homes, sports fields or golf courses.
