Pythium root dysfunction is a fungal disease caused by Pythium spp. that infects grass roots and inhibits their ability to absorb water and nutrients from the soil. When turf is affected, it may appear thin, off-colour and slow growing. In cool and wet conditions, Pythium root dysfunction may first appear as small, diffuse, yellow patches of turf 4-7cm in diameter.
What are the symptoms of Pythium Root Dysfuncton?
General symptoms of pythium root dysfunction include:
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 watersoaked and root systems are greatly reduced in volume and vigour.
