Causal Agent: Gaeumannomyces graminis var. avenae

Susceptible Turfgrasses: Bentgrass

Symptoms

  • Small, light brown dead patches appear on turf.

  • Patches once established continue to spread throughout the year.

  • Stressed grass appears bronze to reddish brown and then fades to a dull brown.

  • During winter affected patches turn grey.

  • In pure Bentgrass stands a circular or ring-shaped dead spot occurs.

  • Patches may enlarge (up to 15cm a year) to reach diameter of 1m or more.

  • Or patches may appear briefly and then cease to spread.

  • Affected patches do not usually heal rapidly and the centres are invaded/ colonised by Fescue and weeds.

  • In mixed stands, the Bentgrass appears yellow-brown to brown, leaving a thinned overall stand dominated by Wintergrass or Fescue.

  • Stolons, rhizomes, roots and bases of shoots become dark brown to black before they are killed.

  • Less severely infected tissues often bear dark strands of mycelium oriented primarily parallel to the root axis.

Conditions Favouring Disease

  • Severe during cool, wet years and in poorly drained turf.

  • Greatly enhanced on turfgrasses grown in soils with high pH.

  • Increasing acidity tends to suppress this disease.

  • Soil conditions favouring the disease include, light texture, low organic content, low or unbalance fertility, soil pH above 5.5.
