It takes three things to have a turf disease problem:

• A susceptible host;
• a pathogen;
• and the right environment.

If any one of these is missing, there will be no disease development. Healthy, vigorously growing, adapted lawn grasses that are properly managed can best survive disease outbreaks. Proper lawn care includes fertilizing, watering, mowing, and insect and weed control. While proper care does not completely prevent diseases, it helps to curb them so that controls can be more effective if they become necessary. Many questions need to be answered before chemicals are applied to a lawn. You must be patient regarding lawn diseases. When weather conditions favoring the development of the disease pass, the disease will go into remission and generally the turf will recover.
