Here in Knoxville, Brown Patch (also called large brown patch or Rhizoctonia blight) is the most common disease that threatens our lawns. Brown patch is a fungal disease that can present a serious threat to our lawns. We offer a disease control program that will help insure that brown patch lawn disease does not can extensive damage to your lawn.
Brown patch commonly starts as a small spot and can quickly spread outwards in a circular or horseshoe pattern up to a couple of feet wide. Some times, while expanding outwards, the inside of the circle will recover, leaving the brown areas resembling a smoke-ring. Brown patch can harm a lawn's appearance and cause permanent loss of grass plants that are less than 1 year old.
Summer Patch disease appears as light green patches in the lawn that spreads out eventually turning a reddish brown and then die.
The disease formerly called "Fusarium Blight" or "Fusarium Blight syndrome" was once thought to be a distinct disease characterized by patches of grass that develop "frog-eye" patterns. These consist of donut-or crescent-shaped areas of dead or dying grass with a center of green grass. This disease is recognized to be a complex of rather similar appearing diseases that include Necrotic Ring Spot, Rhizoctonia Yellow Patch, and Summer Patch.
Summer Patch lawn disease is known to attack certain grasses and avoids other grasses altogether. Most commonly attacked include: creeping bentgrass, annual bluegrass, Kentucky bluegrass and fine fescue.
Dollar spot is most common on Kentucky Bluegrass and Bent Grass here in Knoxville. They get their name from their small silver dollar-like shape, but can begin as the size of a small grapefruit. Usually looks brown or straw-colored in appearance. The spots may merge to form large patches several feet wide
Dollar spot is most common during warm, wet weather with heavy dews and in those lawns with low levels of nitrogen.
Red Thread lawn disease is most common to Fescues, Ryegrasses, and Kentucky Bluegrass during wet and cool weather.
Pinkish-red threads form around the leaf blades and bind them together. Eventually, the affected grass will turn brown.
It attacks only leaves and leaf sheaths and is seldom serious enough to kill a lawn..
Named from the orange, "rusty"appearance this affliction gives leaf blades. Most commonly effecting ryegrasses and Kentucky Bluegrass, rust tends to flourish in conditions of: morning dew, shade, high soil compaction, and low-fertility. The best way to check for rust problems is by taking a white tissue or paper towel and rubbing a few grass blades through it. When rust inflicted grass is mowed it collects on shoes.
