Which of the following is identified as a turf disease in the material?

• A. Slime mold
• B. Thatch buildup
• C. Brown Patch
• D. Dollar Spot decay

Answer: (D)

The concept here is recognizing a turf disease as a pathogen-caused problem that directly damages the leaf tissue and turf quality. Dollar Spot decay is identified as a turf disease in the material because it is a specific fungal disease that attacks turf leaves, producing small, round spots about the size of a dollar under warm, humid conditions. It’s a true disease, not just a surface growth or a turf condition.

Slime mold isn’t a disease that injures leaf tissue in the same way; it’s more of a surface growth that feeds on decaying organic matter. Thatch buildup is a buildup of organic matter between the soil and leaf crowns, not a disease. Brown Patch is also a turf disease, but the material identifies the condition described as Dollar Spot decay, which is the symptom pattern the item points to.
