Dollar Spot
The Issue
Causal Agent: Dollar spot (Clarireedia jacksonii)
Hosts: All turfgrasses in Canada
Epidemiology: Summer through fall during periods of higher humidity and air temperatures between 15 – 29°C (60-85°F).
Target: Foliage
Evidence: In closely mowed grasses, mycelium from previously infected tissue (thatch) will colonize the foliage resulting in small, circular, sunken spots of white or tan coloured blighted turf. These spots rarely exceed 5 cm (2 inches) and are the size of a silver dollar which the name is derived from. These spots can coalesce into larger patches under severe conditions.
Clues: Cobwebby mycelium covering foliage which can have a spider web like appearance. Lesions on foliage can often have an hour-glass appearance with tan to reddish brown margins which usually extend across the entire leaf blade.
