Dollar Spot - Australia

All turf species

• Closely mowed areas – sunken circular tan coloured spots (less than 5 cm).
• May coalesce into larger areas – especially higher mowed turf.
• Closer inspection reveals water soaked lesions that will turn tan (hourglass) with definite reddish-brown margins.
• Infection will rarely progress to crown or kill plants completely despite leaves being totally blighted.
• May be confused with early Pythium Blight and Red Thread.
• Humid, cool conditions may see the development of white mycelial growth on infected tissue.
