In the turf disease management pyramid, which item is not typically included?

• A. Fungicide
• B. Soil moisture
• C. Sunlight
• D. Soil fertility

Answer: (A)

Prevention through how you manage the turf environment is the centerpiece of the disease management pyramid. The base is built from factors you can actively control to reduce disease pressure, not from chemical interventions. Fungicide is a chemical control used when risk is high or disease is already present, so it sits higher in the pyramid as a reactive option rather than a foundational element. In contrast, soil moisture management, adequate sunlight, and proper soil fertility are included because they shape the environment in ways that limit pathogen success and help the turf stay healthy and resilient. Controlling irrigation to avoid leaf wetness, ensuring enough light to reduce humid, shady conditions, and maintaining balanced fertility all work together to prevent disease, which is why these elements are part of the pyramid while fungicide is not.
