  2. Diagnosing Turfgrass Problems
    Source: Department of Crop and Soil Sciences Publications

    "The cause of turfgrass damage is often difficult to determine if considerable time has elapsed between damage and diagnosis. Damage is often blamed on disease or insects when there is no sound basis for such a diagnosis. A careful diagnosis involves analysis of climatic and environmental conditions, along with the management program followed. It is important to know what fertilizers, insecticides, fungicides, or herbicides have been applied, the amounts used, and the time and method of application."

  4. Disease Management in Turf
    Source: Department of Crop and Soil Sciences Publications

    "Disease in turfgrasses, as in other plants, develops from an interaction among a susceptible plant, a disease-producing organism (pathogen), and an environment favorable for disease development. Susceptible grasses and pathogens (usually fungi) are present in all lawns. In most cases, the pathogens exist in a dormant or saprophytic (feeding on dead or decaying substances) state and do not attack living plants. Diseases occur when environmental conditions (weather, management, and / or site conditions) become favorable for the build up of pathogen populations and / or cause an increase in the susceptibility of the plant. When this happens, turfgrass loss can occur."
