Red thread disease is a fungal infection found on lawns and other turfed areas. It is caused by the corticioid fungus Laetisaria fuciformis and has two separate stages. The stage that gives the infection its name is characterised by very thin, red, needle-like strands extending from the grass blade.
The fungus survives the winter on the surface of the host plant, such as on bark or buds. [2] In late winter or early spring, rainwater washes spores into the buds as they burst. Once this happens, no treatment is effective. In the spring, about two weeks after blossom, new leaves emerging from the infected buds are infected by the conidia.
