Lawn Insects & Diseases

Brown Patch
Brown Patch lawn disease
Brown patch is a fungus that attacks St. Augustinegrass in the fall and is treated with a fungicide. It does not kill the grass, but it does cause large unattractive brown circles. The affected areas will slowly recover the next spring when the grass is growing rapidly. If you have experienced brown patch in the past, chances are high that your lawn will develop the disease every fall.
Gray Leaf Spot
Gray Leaf Spot lawn disease
Leaf spots first appear as tiny brown to ash-colored spots with purple to brown margins that enlarge and become elongated or diamond-shaped. Sections of the leaf blade will also turn yellow. In severe cases, lesions develop on stems and spikes, and the leaves wither and die. Turfgrass may have a burned or scorched appearance resulting from death or spotting of the leaf blades. Leaf spot is treated with a fungicide.
Take All Patch
Take All Patch lawn disease
Early symptoms appear yellowing and thinning turf in circular or irregular patches. The roots are often short, blackened and rotten. The grass stems (stolons) can often be lifted from the soil due to the poor root system. The yellowing grass blades eventually die and become brown, followed by stolon death. The disease is treated with good watering practices and an application of sulfur.
Chinch Bugs

The chinch bugs suck the plant juices and releases a toxin that causes yellowish to brownish patches in the lawn. The most common areas to begin to see chinch bug damage is along a driveway, curb, sidewalk or foundation of a home due to the heat emitted from such objects.
