How To Identify Slime Mold
Slime molds are harmless fungi that feed on decaying organic matter. They live on the soil, thatch, or surfaces of grass foliage. During warm weather white, grey, or blacked masses grow over grass blades after a heavy rain or watering. Slime molds develop in streaks or small patches that smother, rather than consume, otherwise healthy turf. The masses then dry and form unsightly gray crusty mats.
Slime mold is not necessarily bad for your lawn, it just ruins your lawn cosmetically. When your lawn dries out, the infected areas may turn yellow, but within a few weeks the slime mold may be gone completely. However, sometimes a fungicide will be required to get rid of slime mold completely.
Slime Mold Removal
Slime mold disappears fast and usually doesn’t occur more than once per season. First, we recommend getting rid of slime mold by raking or washing the leaves of the grass. If this does not work, a fungicide may be necessary. We have had success with using SePRO Pentathlon Fungicide to both prevent and control slime mold. SePro Pentathlon Fungicide also works on other lawn diseases such as Brown Patch and Dollar Spot.
The rate that this fungicide should be applied for slime mold is 10 oz per 1000 square feet. However, refer to the label of Pentathlon Fungicide to confirm. This fungicide can be applied to flowers, foliage plants, ornamentals, and turf.
First, you will need a sprayer. We recommend the Chapin Pro Series Four Gallon Backpack Sprayer. After you are finished mixing the fungicide with water, make sure the tank is properly mixed together by shaking it a few times. If there is not proper agitation, this fungicide will not be effective at getting rid of slime mold. Be sure to wear protective gear including Nitrile Chemical Resistant Gloves and a Respirator Mask.
