RED THREAD

What is red thread

Red thread (Laetisaria fuciformis) is, as the name suggests, a reddish fungus that grows on blades of grass. Typically seen in the summer months on lawns that have a nitrogen deficiency, if left untreated this condition can spread to large portions of the lawn. 

How can I spot red thread?

The fungus produces thread-like strands or web areas of coral pink to blood-red hyphae on the tips of grass blades. The strands can protrude up to 2cm upward from the blade tips and are easily seen.

How do I treat red thread?

The best solution is to keep the soil well fertilised, provide good soil drainage, help to avoid the grass from overheating and do not allow thatch to accumulate. Where disease is severe, fungicide applications may be necessary.
