Stressed grass appears bronze to reddish brown and then fades to a dull brown.
During winter affected patches turn grey.
In pure Bent Grass stands, circular dead spots occur.
Patches may enlarge (up to 15 cm a year) to reach diameter of 1 m or more or may appear briefly and then cease to spread.
Affected patches do not usually heal rapidly and the centres are invaded/taken over by Fesuce and weeds.
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 turf 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.
Use acidifying fertilisers.
Apply moderate to high levels of phosphorous, potassium and minor elements where these nutrients are depleted from the soil.
Improve drainage of turf.
When liming apply the coarsest grades of lime to avoid rapid changes in pH.
Removal of diseases patches and resodding where small areas are affected.
Preventative systemic fungicide applications.
Take-All Patch predominately affects newly sown Bent Grass golf greens. In mixed stands, the Bent Grass appears yellow-brown to brown, leaving a thinned overall stand dominated by Winter Grass or Fescue.
