Spring Dead Spot in Bermudagrass: Cultural Management Over Fungicides

Spring dead spot (SDS) appears as softball- to beachball-sized dead circles in May–June. The fungus infects in fall; symptoms show after winter stress.

Integrated Management

• Avoid excess nitrogen—3 applications/year max.
• No nitrogen after late August.
• Raise mowing height ½ inch by Labor Day.
• Ensure adequate soil potassium (soil test).
• Reduce thatch via aeration and core pulverization.
• Fall fungicides (myclobutanil or Bayleton) can suppress SDS.
• Plug dead spots with healthy bermudagrass now.
