Lawn Diseases

Lawn diseases are almost always a fungus.  If the fungus is not correctly identified and treated it will spread and damage your entire lawn. An accurate diagnosis is essential to ensure the correct lawn treatment is applied.

A lawn care maintenance programme can help prevent lawn fungus.

• Most fungal diseases use the moisture on the leaves of grass plants to produce and move spores. Avoid watering just before dark as water will remain on the leaf blades longer at night.
  
  
• Mowing less frequently during humid hot weather reduces stress on the grass plants and minimises the possible transfer of grass diseases.
  
  
• The way you mow affects your lawns ability to resist diseases. Mowing too low increases the chances of scalping. Cutting your grass extremely short is very stressful to the plant and leaves it susceptible to lawn diseases.
  
  
• Blunt or dull mower blades shred the tops of the grass leaves, and expose tissue for lawn diseases to enter the plants easily.
  
  
• Often, lawn diseases are specific to certain varieties of grass and one approach may be to introduce other varieties of grass into your lawn.
  
  
• Increase light, air access and movement over the grass by pruning overhanging trees and shrubs, will all help reduce incidences of turf disease.
  
  
• Lawn aeration also helps produce healthy grass.

Implementing the above good practices will help reduce the likelihood of a lawn disease. These techniques along with the potential use of a fungicide will help reduce incidence as part of a Integrated Disease Managment  Plan. A professional fungicide may have to be applied to control the most damaging lawn diseases. These products are not available in DIY stores.
