Slime Mold in Turf

Alfredo Martinez, Mila Pearce, Lee Burpee
University of Georgia

Symptoms:

Large numbers of pinhead-sized fruiting bodies may suddenly appear on grass blades and stems in circular to irregular patches 1-30 inches in diameter.

 Affected patches of grass do not normally die or turn yellow and signs of the fungi usually disappear within 1 to 2 weeks. These fungi normally reproduce in the same location each year. The fungi are not parasitic, but they may shade the individual grass leaves to the extent that leaves may be weakened by inefficient photosynthesis.

Conditions Favoring Disease:

Slime molds are favored by cool temperatures and continuous high humidity. An abundance of thatch favors slime molds by providing food directly in the form of organic matter.

Management Tips:

Management Tips:

  • Remove slime mold by mowing.
  • Remove using gardening tool or high pressure stream of water.
