Endophyte-enhanced grass overview

Endophytes can be found in certain turfgrass species and cultivars. Endophytes enable the plant to resist feeding of some insect pests and have also been shown to increase stress tolerance. Rutgers University has determined % endophyte infection of entries in several NTEP tests (see links at left). Endophyte infection percentage pertains only to the seed lot in NTEP Tests. Also, Rutgers testing did not distinguish between "live" and "dead" endophyte.
