Yellow brown patches in your lawn usually but not exclusively during autumn and a white grey coloured mould particularly in shaded areas are indications of Fusarium patch. Lawns receiving too much nitrogen feed are susceptible as are lawns on compacted soil. Aerating and ensuring the grass receives a balanced fertiliser feed program can cure Fusarium patch.

Serious infestation will require a fungicide treatment.

Handy Tip:  Keep leaves, grass cuttings and snow off the lawn to minimise risk of infestation.
