Lawn Diseases

Most lawn diseases are caused by an imbalance or reaction in the natural funghi population present in all fine turf.

For the most part, funghi do not cause disease. In fact, they help degrade thatch. Funghi cause disease in turf when two events occur:

  • The weather is conducive to disease
  • The plant is susceptible to infection

While diseases in lawn turf are not common, they are natural and will occasionally develop when conditions are right.

Some diseases develop in the spring, some in the summer, and others in the winter months.

Fortunately, diseases that can kill your turf are rare and those that are more common are not very damaging.

The best defence against disease development is to select those grass varieties with the greatest disease resistance.

And to take good care of your turf. Well managed lawn turf will not only develop less disease, but it will recover from disease faster.
