Which statement best describes the approach to necrotic ring spot management in turfgrass?

• A. Integrated Disease Management is employed
• B. Chemical controls alone are sufficient
• C. Watering alone cures the disease
• D. Mowing height is the only important factor

Answer: (A)

Managing necrotic ring spot effectively requires an approach that combines cultural practices, resistant options when available, and targeted chemical use as part of a plan. This disease occurs where turf is stressed and environmental conditions favor the pathogen, so the best control is not a single tactic but a coordinated program that reduces stress, improves plant resilience, and limits disease development. Integrated Disease Management includes appropriate irrigation practices to avoid excessive leaf wetness, improved drainage and soil structure, regular aeration and thatch management, mowing at a height that maintains healthy leaf tissue, balanced fertilization to prevent weak, lush growth, and the use of resistant or tolerant turf varieties when possible. Fungicides are used judiciously as part of a broader strategy, not as the only solution. Relying on chemicals alone ignores environmental and cultural factors that drive infection, watering alone doesn’t eradicate the pathogen once established, and mowing height by itself doesn’t address the underlying stress or disease dynamics.
