[vc_columAnthracnose can occur all year round but most likely to be seen during late summer through into winter. There are no distinct margins to the damage caused but usually seen as irregular spots. Frequently attacks annual meadow grass. Plants infected with anthracnose turn yellow; sometimes the youngest leaf has a red or red/orange tinge to it. The plant can be easily pulled from the sward and small black ‘pin-head’ type structures can usually be seen on the base and root of the affected plant.
Grass species affected – Particularly severe with annual meadow grass (Poa annua), but can also attack ryegrass (Lolium spp.) and fescue (Festuca spp.)
Factors promoting infection – Poor turf conditions encourage this disease such as compacted soil and low fertility. Long spells of wet weather and poorly drained soils will also favour attack.
