Spring dead spot

The Spring Dead Spot fungus is active in many areas of Australia. The late finish to summer may keep the fungus active longer than on other years. The fungus starts to colonize couchgrass roots when soil temperatures fall to around 24°C. This is good timing for the first fungicide application. The second application should be made approximately 4 weeks later and before soil temperatures fall below 16°C.
