Valley Seeds perennial ryegrass varieties are persistent and Staggers Free
Ryegrass staggers is caused by endophyte and many overseas bred varieties need endophyte to enable them to persist in Australian conditions. Valley Seeds varieties are bred from plants selected in Australia that do not have endophyte and therefore do not need this foreign fungus to persist.
These varieties have genetic persistence rather than relying on this often toxic fungus to support their persistence.
There is no longer a need to manage the negative aspects of endophyte. Your livestock productivity, health and welfare are protected when livestock graze Staggers Free varieties.
