Lawn Disease In Your Lawn, Here Are Common Lawn Diseases:
Lawn Disease In Your Lawn Brown Patch:
One of the most widely spread diseases that can affect almost any cool-season turf lawn in many parts of the country is brown patch. When nighttime temperatures start hovering around 65 to 70 F in early summer, this disease can wreak havoc on tall fescue, Kentucky bluegrass and perennial ryegrass.
Pythium outbreaks are generally associated with poorly drained soils or damp, humid conditions in the turfgrass canopy with little drying of the turf leaves. Newly seeded areas receiving daily irrigation can provide ideal environments for pythium development. Pythium blight symptoms include circular areas 1 to 3 inches in diameter and foliage can have a gray, water-soaked appearance and possibly white mycelium on mornings with dew.
Under very wet conditions, white mycelium may be visible in the patch and the margins may be reddish pink. The patches become tan and bleached of color under dry conditions.
Symptoms generally are expressed as circular patches of tan or brownish turf late in the summer. This particular disease does its damage in the late spring to early summer but symptoms are not expressed until the turf is under stress later in the summer.
These diseases are more damaging on under fertilized turf. Often an application of fertilizer will alleviate disease severity.
- Occurs late spring through fall. Causes most damage in June-July.
- Usually more prevalent on under-fertilized turf.
- Drought, thatch, and compacted soil increase disease susceptibility.
Various species of mushrooms may appear in lawns after wet weather. A mushroom is the spore-bearing or fruiting structure of a fungus that grows in the soil. The fungus feeds on dead organic matter such as dead tree roots, buried logs, and stumps. These fungi may live for many years until the wood is completely destroyed.
How can you manage your lawn diseases issue in your lawn? Proper fertilization and mowing, irrigation, and improving poor drainage.
These will all help manage your lawn issues. Diseases can always be present in your lawn and when lawns are stressed the lawn disease will appear.
Diseases in your lawn can be caused by over fertilization when you are using a chemical product. Be sure to follow the rate per 1,000 sqft. Changes in the weather temperatures and rainfall often will stress the lawns and promote disease.
Applications by homeowners tend not to be very effective. By the time disease symptoms are noticed it is too late.
