The tall fescue and perennial ryegrass with AVANEX® Unique Endophyte Technology are generally adapted to the cool, humid regions in the Coppen climate classification. Tall fescue and perennial ryegrass have different zones of adaptation, so the choice of species needs to be made on a site specific basis.

To achieve the best performance from turfgrass with AVANEX® it needs to completely replace any existing turfgrass and prevent invasion by other grass. The existing grass cover needs to be destroyed and re-sown with AVANEX® turfgrass. Do not sow turfgrass with AVANEX® in a mixture with non-AVANEX® grass.  For airports, a best practice guide has been developed to minimise the risk of attracting birds by activities associated with sowing AVANEX® grass.
