Pythium Root Dysfunction

Causal Agent: Pythium spp.

Susceptible Turfgrasses: Cool and warm season grasses.

Symptoms

Affected turf may appear thin, off colour and slow growing.
This may occur in small patches or as a general decline and loss of large turfgrass area.
Under cool, wet conditions symptoms may first appear as small, diffuse yellow patches of turf 4 to 7cm in diameter.
As temperatures rise, large areas of turf may wilt, turn brown and die.
In severely infected plants, crowns may appear water-soaked and root systems are greatly reduced in volume and vigour.
Roots and crown may be extensively discoloured.
No foliar mycelium is evident during infection.

Conditions Favouring Disease

Hot days (30-35°C), humid or rainy weather when night temperatures are warm (above 20°C).
Relative humidity exceeding 90% for at least 14 hours and a minimum temperature not falling below 20°C.
Pythium Root Dysfunction occurs in areas with high soil moisture, poor drainage and low light.
Areas with low mowing height and excessive wear.
