Treatment Of Fungal Diseases In Your Lawn

Fungal diseases can strike your lawn when the weather takes a turn. Damp and humid conditions can form these diseases in your lawn. When they take hold of your lawn it is important to identify and target them quickly.


Knowing the signs of a fungal related problem are important before they become more prevalent in your lawn. Signs include:

  • Yellow, white or brown coloured patches.
  • Thinned out areas of lawn.
  • Irregular discolouration of leaf blades.
  • Coatings or threads on grass blades.


Weather conditions can cause havoc on your lawn with fungal diseases becoming more prominent from:

  • Humidity.
  • Overwatering.
  • Compaction of soil.
  • Over fertilisation or using the wrong fertiliser.
  • Wrong grass variety for your space.
  • Poor mowing habits.


If fungal problems have overtaken your lawn, you will need to apply a fungicide.

Fungicide products such as:
