Brown Spot Lawn DiseaseAchieving a picture perfect lawn can be a daunting task. Nevertheless, a critical part of lawn care is knowing how to identify and treat any lawn fungal disease before it multiplies and compromises your entire lawn.

Fungus ranks highly among the general lawn diseases by taking varying forms including rings, dead-looking brown patches, threads, or slimes. Luckily, proper turf management practices can go a long way in eliminating lawn fungal diseases. Here are some remedies on how to deal with lawn diseases.

Causes of Lawn Fungal Disease

Although disease spores may be present at any time in your lawn, an outbreak will not occur unless some of these factors are present:

  • A grass variety (host plant) susceptible to attack by a particular fungus species.
  • A disease organism or simply the pathogen.
  • Favorable environmental conditions (both man-made and natural) that potentially encourage the development of the disease such as, temperature, moisture, over watering, over fertilization or using the wrong kind of fertilizer, improper mowing (mowing too low), and soil compaction.
  • A means of spore distribution such as foot traffic, lawn mowers, wind, water, and infected grass clippings.
  • Different Lawn Diseases and their Identification

    Brown Patch
    Also known as the summer blight, it is characterized by circular rings on the grass resembling smoke rings. It occurs when the night temperatures stay above 70 degrees and when the relative humidity is 100%.

    Dollar Spot
    This disease appears on the lawn during cool periods in spring, summer, or fall. It shows itself in brown circular patches the size of a silver dollar with growths similar to cobwebs, whenever due is present.

    This is probably the most common fungal lawn disease. It is characterized by white powder forming on the grass and under severe conditions; you can see it fly in tile air when you touch the grass. Some varieties of grass susceptible to mildew are Windsor, Merion bluegrass, Pennstar, and Fylking. Resistant varieties include the Delta, Kentucky bluegrass, Nugget, Park, Fescue, and Newport. Fescue grass is also shade tolerant.

    Turf Blight
    This is a very dangerous disease that kills grass by striking the roots and crowns. It results in brown discoloration of grass and often erroneously blamed on drought or poor nutrition.

    Characterized by red spots on turf often due to lawn mowing or foot traffic.

    How to Prevent and Treat Lawn Fungal Diseases

    Some varieties of grass species such as the Kentucky bluegrass and the fescue are resistant fungal diseases. However, if replacing your sod is not an option there are other effective control measures, such as:

    Mow the lawn regularly based on the grasses growth rate to keep it at the recommended mowing height. This will improve its disease resistance ability as well as enhancing its aesthetic appeal.

    Always apply the correct type and amount of fertilizer to influence growth and recuperative ability of stressed grass. Also, avoid excess nitrogen. Instead, try using organic slow release fertilizers.

    Watering early in the day prevents high evaporation rates. Watering in the afternoon is wasteful because of extreme evaporations, also, prolonged damp conditions create a healthy environment for disease development.

    Soil cultivation and thatch removal
    Soil compaction hardens the soil reducing growth rate and recuperative ability of the grass. This in turn increases the lawns susceptibility to disease. Cultivating the soil and dethatching allows aerating and better shoot and root growth.
