Turfgrass diseases are difficult to understand because the organisms causing the problems are rarely observed. Fortunately, grasses maintained using proper cultural practices (water, mowing, and fertility) are not as likely to become diseased or be as severely damaged as grasses not receiving proper care.
There are two common patterns of turfgrass disease symptoms. One is a circular patch of turfgrass, either small or large, that is no longer uniformly green. The second is turf that has “spots” on the leaves. If disease patches are present, examine the leaves and roots in these patches for characteristic symptoms of disease and signs of actual fungus. The best time to observe fungus in the lawn is in the early morning when dew is still present. For turf with spots, note the color and shape of the spots.
There are three steps to disease management. First, correctly identify the disease. Second, identify the conditions promoting disease development. Third, identify the management techniques that will alter or eliminate these conducive conditions.
It is important to know and realize that control of plant diseased leaves must be preventative. Once a plant gets a disease, we cannot cure it. All we can do is protect the undiseased leaves and new leaves as they emerge. The diseased leaves drop, and the plant thus appears to have been “cured” of the disease.
To try to describe there even a part of the thousands of diseases which attach ornamental plants is prohibitive. So, we will describe only a few of the most common diseases which we encounter here in beautiful Southwest Florida.
