Dollar Spot


Dollar Spot is a fungal disease that affects turf grasses. It is most commonly found on closely mowed grasses, for example golf courses. The fungal pathogen overwinters and survives harsh conditions as dormant mycelium on infected plants.

Dollar Spot commonly occurs from early spring to late autumn and is most prominent in periods of warm and humid conditions.

The main symptoms are clusters of sunken brown/ straw-coloured spots approximately the size of a silver dollar (hence the name). In the early stages of Dollar Spot the grass may seem wilted and water-logged, however the spots quickly fade to brown.

Using a scarifier to aerate the soil and remove thatch will also help to prevent the disease as the soil can dry quicker.
