ERI or Ectotrophic Root Infecting Fungi

Also referred to as Couchgrass Decline, turf grass symptoms of ERI disease start by thinning out of the surface and can include straw-coloured patches that range in size from 30 cm to 1 metre in diameter.

Ectotrophic root-infecting fungi (ERI fungi) are a factor in causing patchiness and poor root health in couch grass. The term ‘ectotrophic’ means these fungi grow over the root surface before they penetrate into the inside of the root. ERI fungi involves a number of fungal species.
