This is a remarkable product for you can get a correct MicroLife Fertilization and fight turf disease at the same time. MicroLife Brown Patch is cheaper to use than a stand-alone chemical fertilizer and chemical fungicide. If there is one thing we never want to use it's a chemical fungicide for they destroy all life in the soil, including the good guys. And chemical fertilizers never properly feed the plants and will never improve soil health which then leads to disease problems. Use on: St. Augustine with Brown Patch Problems, New Sod/Plant Installs, Ornamentals
