Anthracnose

Symptoms: Basal rot: Youngest leaf brick red, other leaves bright yellow, black rot at base of stem. Foliar blight affected leaves lose colour to become a yellow colour and black spots containing fruiting bodies (acervuli) can be seen on the leaves.

Main Causes: Stress and poor growing conditions.

Time of Year: Basal rot: Autumn and Winter. Foliar blight: Summer.

CONTROL

Cultural: Ensure adequate drainage; reduce surface moisture; maintain appropriate fertility; control thatch layer; encourage morning sunlight penetration; relieve compaction; increase cutting height.

Biological: Discourage annual meadow-grass in the sward.

Chemical: Effective fungicides are available. Timing of application dictates optimal performance. Preventative use during periods of high disease pressure provides optimal control.
