Yes but that isn't the same as novel enophyte.  It is endo free thus not as strong a plant.  However we bought a crp farm in 2002 had been in fescue for two crp terms and we were thinking of leaving it in grass.  So I tested it and it came back if I remember 80% clean 20 endo.  This had been planted with year old seed thus endo free.  I feel the reason it stayed 80% was the fact there was never any stress on the plants thus the endo type didn't get a foot hold.  We put it into crop 2 years later.  Ben
