Spring Dead Spot

Spring Dead Spot can be identified as yellow or brown patches in the lawn ranging in size between 10 cm to over a metre in diameter. As the name suggests, Spring Dead Spot is most noticeable in Spring as the lawn colour darkens. However, it actually begins in Autumn and continues over the Winter when it may be less noticeable due to lawns being lighter in colour during these times. As Summer arrives, Spring Dead Spot will become far less active, and the lawns in turn become more active, this leads to the lawn growth outpacing the damage occurring from SDS. So Spring Dead Spot becomes far less noticeable or possibly invisible during the Summer. Spring Dead Spot is a lawn fungus disease caused by the pathogen Leptosphaeria spp. Even though the leaf of the lawn is seen to be dying, the fungus actually attacks and destroys the roots and rhizomes (underground runners) of the lawn.
