Lawn Fungus Control is a systemic fungicide for both preventative and curative treatments. Fungus is seen most often at temperatures of 80°F when humidity levels are very high. It spreads through mycelia, which “jump” from spot to spot. Mycelia use water and moisture to move throughout the lawn. Therefore, water in the morning and NOT at night to insure that water doesn’t stay on the leaves for too long. Mycelia look like spider webs on the lawn, which appear before damage occurs. If you see these “webs” then apply Lawn Fungus Control. Applying Love Your Soil on the same day will increase water penetration into the soil. This will limit the “swimming” of mycelia and allow your fungicide treatment to be more effective.
