Most pest related damage that occurs on lawns is due to a fungus.
Maintaining a healthy, vigorously growing lawn is the best way to prevent a severe disease breakout.
A careful balance of nutrition, water and temperature has to be maintained; with not too little or too much.
Three factors must be present in order for an outbreak to occur, the pathogen (fungal spores), the host (the grass itself) and the correct environment (humidity and temperature).
The best practices in preventing outbreaks are in selecting the right grass type for your area. One that has a proven defence in your climate, to common diseases. As well as operating correct cultural practices such as feeding, cutting and watering. Getting the levels just right.
It is tricky to identify what disease exactly is affecting a damaged lawn, but factors such as seasonal temperature, damage type, humidity as well as the time of year can all give indicators, once all non-fungal related problems have be eliminated.
Once the disease has been identified it is down to either creating an environment that is less hospitable to the pathogen through such using treatment regimes such as wetting agents or exercising good cultural practices (cutting and correct moisture levels) or trying to eradicate the fungus using selective fungicides.
This can be costly and so it is vital that the exact fungus is identified, otherwise a chemical treatment will not work.
All options can be discussed and priced by ourselves giving you the choice of the best way forward after an outbreak.,
