Most common to Bermuda, Kentucky Bluegrass, Centipede grass, Bent grass, St. Augustine, and ryegrasses in areas with high humidity and/or shade. Brown patch usually begins as a small spot and quickly spreads in a circular pattern.
Most common to Bermuda, Kentucky Bluegrass, Centipede grass, Bent grass, St. Augustine, and ryegrasses in areas with high humidity and/or shade. Starts as small brown spots about the size of a silver dollar. However it can grow together to make a larger spot.
Grows in most grasses and are in the shape of circular rings filled with fast-growing, dark green grass. Around the edges of the circle, the grass usually turns brown and sometimes grows mushrooms. Fairy rings typically grow in soils that contain wood debris and/or old tree stumps.
Affects all grasses in humid climates and is noticed by the slimy brown patches that have a white, cotton like fungus around it. It mats together and appears in streaks across the lawn giving it a “greasy” appearance.
Brown to purple spots on blades that cause irregular dying areas of grass. Excess nitrogen fertility and excess thatch are the main causes
Light green splotches that turn reddish brown and then die
It looks like flour was sprinkled on the grass. The grass will eventually wither and die. Kentucky bluegrass and shad areas are the most susceptible.
Wilted brown grass shaped irregularly throughout the lawn
Appears to give leaf blades an orange color making it look like rust. Most commonly affects ryegrasses and Kentucky bluegrass. Flourishes in conditions of morning dew, shade, high soil compaction, and low-fertility. A good way to check your grass is by taking a paper towel and rubbing a few grass blades through it. If an orange color remains, then it is most likely rust.
Most common to Kentucky bluegrass and fescues in areas where snow falls and sits on the lawn for long periods of time. The best way to prevent snowmold is to aerate your lawn.
Most common to fescues, ryegrasses, and Kentucky bluegrasses during times of moist and cool weather. The leaf blades have pinkish-red threads that form around them and bind them together. Eventually, it turns brown.
