Slime Mold can occur on all turf grasses. Most of the time this disease does not harm the turf, it just looks very unsightly. The whitish, grayish, or purplish pinhead sized fruiting bodies develop on the blades of the turf grass plant.

The development of this disease is favored by periods of rainy weather. Controlling slime mold is as easy as using a strong stream of water to remove the fungal bodies from the turf grass plants. Do not use this method during prolonged periods of wet weather, as it will only make the disease spread. Frequent mowing, raking, or brushing off the masses is helpful in drier weather patterns.
This disease can be expected in the same locations next year, if the environmental factors are favorable. Fungicides can be used to control slime mold if turf becomes severely weakened and the masses become abundant.
