Red thread is a fungal disease that affects turf and lawns. The first symptoms of red thread disease is often the tan colour of dead leaves. Pink, pale red or orange fungal growths may extend up to 10mm beyond the leaf tips, giving red thread disease its name. When these red threads or strands are present, the blighted grass take on a reddish, pink or tan cast that is easily detected.

Circular or irregularly shaped, small to large patches (5 to 15cm) in diameter of infected grass become water-soaked and die rapidly.Â

Dead leaves are generally interspersed among uninfected leaves giving an overall diffuse, scorched or ragged appearance to the patch.Â
Only the foliage is infected and death usually proceeds from the leaf tips downwards.Â
Pink to pale red or orange fungal growths (red threads) may extend up to 10mm beyond the leaf tips.Â
Pink, cottony flocks of mycelium may be produced.Â
