Lawn Diseases


Fusarium Patch

The most common UK lawn disease, caused by the fungus, microdochium nivale.
Cool and wet conditions are favoured by this fungus and also grasses which are weak as a result of lack of nutrition. All UK grasses can succumb to fusarium patch but the disease is normally seen first in Poa annua due to its shallow rooting. Initial infections are small but these can rapidly enlarge.

The disease can be recognised by the white or pink gossamer like mycelium on the leaf surface.

Control

Fusarium can be controlled by the application of an appropriate fungicide.

Red Thread

Red thread infection can occur on all lawn grasses but is particularly common on ryegrasses and fescues.
Mild, damp weather is favoured by this fungus, Laetisaria fucifrormis. Red Thread used to be prevalent on under fertilised lawns but recently we have noticed this fungal disease even on well fertilised lawns.

Red Thread is quite easy to identify by the red shards that grow outwards from the leaf.

Control

Red thread can be controlled by the application of an appropriate fungicide; scarification and aeration will reduce the thatch layer and improve water penetration.

Dry Patch

This phenomenon occurs in the root zone of the lawn, the material making up the root zone becomes hydrophobic or water repellent.
Dry patch normally occurs during the summer and early autumn, it can be prevent or the symptoms controlled.

Control

Dry Patch can be controlled by the application of an appropriate surfactant; Aeration will also improve water penetration.

Anthracnose

In the UK anthracnose only attacks Poa Annua it is caused by the fungus Colletotrichum graminicola.
Periods of cool, wet weather are favoured by this fungus and also grasses which are weak as a result of low fertility or over compacted root zones.

Control

Anthracnose can be controlled by the application of an appropriate fungicide.

Rust

Rust can attack all UK lawn grasses, but is particularly attracted to perennial ryegrass and Poa pratensis.
It can occur throughout the year but is normally seen during early summer to late autumn during mild humid weather.

Rust is easy to identify. The affected grass appears rust coloured due to the spores present on the leaf.

Control

Rust can be controlled by aeration, and depending on the conditions, a light application of fertiliser. Increasing your mowing height and frequency will also aid recovery.

Dollar spot

Dollar spot generally attacks the finer grasses and in particular varieties of red fescue.
Mid-spring to early autumn are the times you will mostly see it often after extended periods of leaf wetness occurring during warm days and cool nights

The main symptoms are numerous small bleached spots.

Control

Dollar spot can be controlled by the application of an appropriate fungicide and aeration.
