Circular patches of bleached, straw coloured dead grass appear in spring as the dormant grass regrows. Patches reappear and expand in the same spot for 3 or more years.
Spring Dead Spot
- General Information
Conditions Favouring Disease
Most active when temperatures are cool and soil is moist. SDS favours cool, wet weather in the spring and autumn and daily temperatures of less than 15 degrees C. Typically found where thatch is more than 1.2 cm thick and in locations with poor drainage and low potassium levels. Heavy applications of nitrogen in late summer can often increase severity the following spring..
Management Tips
Preventative systemic fungicide applications during late summer and autumn. Maintain good nitrogen and potassium levels. Improve drainage and remove thatch. SDS is typically a disease of mature turf that is intensively managed.
