What leaf diseases affect lawns in this area?
Diseases on lawns produce many symptoms. The symptoms depend upon the weather patterns, the particular fungus involved and the variety of turf grass in your lawn. Turf varieties differ widely in their susceptibility to fungal diseases.
Today, there are many new grass varieties that are more resistant to diseases than were previously available. Additionally, many cultural practices can keep your lawn healthy and help prevent disease.
Practices such as proper watering amounts and timing, timing and amount of fertilizer, mowing heights and their frequency, and thatch, all can contribute to the incidence or lack of disease.
Each maintenance practice is different for cool-season and warm-season (zoysia grass) grasses. Consult the appropriate FAQ’s for answers to each specific maintenance practice depending on the type of turfgrass in your lawn.
Environmental conditions such as temperature, rainfall, light, and air currents can also contribute to the incidence or lack of a disease.
There are a number of fungal diseases that affect both cool-season and warm-season lawns. See "Fungal Diseases of Lawns."
For the most common diseases found in cool-season lawns (turf type fescue) see:
