Red Thread

Red Thread

Red thread is a common lawn fungal disease predominantly found during warm wet conditions typically a wet summer and autumn.

OVERVIEW

Red Thread is often seen on lawns in the UK normally from mid summer through to and including the autumn. It is often seen on fine fescue lawns, but can develop on all lawn types.

It is a fairly minor disease that in most cases does relatively little damage, but can spoil a well kept lawns appearance. It is spread by spores within the air.

Red Thread

Normally an application of extra feed will encourage the grass to out grow the disease.

What Grasses are affected?

It is often seen on fine fescue lawns, but can develop on all lawn types.

Why causes the disease?

Disease is caused by two stress factors biotic and abiotic, such as temperature extremes, humidity, air flow and lawn cutting height.

If your lawn has been affected by disease, ask could you change any of the above to reduce the ideal conditions the disease likes?

What does it do?

It can leave patches of turf in a ‘straw like’ brown condition, which can leave the entire lawn with an all over unsightly mottled effect. Studied closely you may see red needles or pink ‘cotton-wool’ like growth on the affected areas. This is the manifestation of the fungus. More often than not, the disease will run its course and as the turf grows the disease becomes less obvious, it is very rare for the disease to be deemed worthy of specialist treatment.

What treatments can be used?

On many occasions an application of fertiliser is more than sufficient to promote lawn growth, affected grasses would then be removed by cutting. The feed will also strengthen the plant, enabling it to “outgrow” the disease. If conditions are suitable, typically in the Autumn, soluble iron can also be used to dry out the fungal disease.

Soil Beneficial treatments will help with building up the plants natural ability to withstand and recover from infections plus dont forget to review the abiotic reasons above.

Best Practice?

When looking at treating disease, you should always consider before applying chemicals what cultural and biological improvements can be used first.

The process of completing two actions dramatically increases your chance of success.

 

Can anything be done now?

Normally the promoting of new growth with the fertiliser will help, as you then cut out the active fungal growth, We would suggest to check to see if you’re looking at the primary effect i.e. red spikes or the secondary effect of the brown ‘straw like grasses’, affected brown grasses will not revert to green, until new grass growth occurs.

If Primary effect:

If it is red spikes of fungal activity, this is already the later development stages, an application of a liquid feed would be beneficial, combined with a frequent cut to remove the affected grasses, but you may choose to treat with a contact fungicide for additional protection. If you would like us to treat your lawn, we can provide a quotation for this.

For best results the fungicide should be applied soon after cutting. Our fungicide will give up to 4 weeks protections. For preventative measures, this application should be repeated at least every month.

Please remember that, similar to taking antibiotics, after you have applied a fungicide, it is it doesn’t guarantee you never get the symptoms again.

If you want to treat yourself, we would suggest using a product called Bayer Lawn Disease control is applied, if necessary. (Lawn Disease Control)

Use as directed and always read and follow the manufactures instructions before use.

If Secondary effect

Rake out brown patches and overseed the area with a good quality grass seed. We recommend and stock Green Velvet, modern mixes like Green Velvet All Rounder are more resistant to fungal diseases like Red Thread .

What could I expect the lawn to look like after a fungicide treatment?
