Which strategies may be used to manage fungal diseases in turf?

• A. Sanitation, use of disease-resistant grasses, good cultural practices, and fungicides
• B. Biological control agents are the most effective option
• C. Rely solely on irrigation management to control diseases
• D. Ignore cultural practices and apply only a single fungicide

Answer: (A)

Managing fungal diseases in turf requires an integrated approach that blends sanitation, resistant grasses, good cultural practices, and fungicides. Sanitizing—removing diseased debris and thatch—reduces the amount of pathogen inoculum available to start new infections. Using disease-resistant grass varieties gives you a genetic baseline of tolerance, making it harder for pathogens to establish and spread. Good cultural practices, such as proper mowing height, balanced fertility, adequate drainage and air movement, and irrigation that avoids excessive leaf wetness, create conditions that are less favorable for fungi and help turf recover when stress is reduced. Fungicides provide a protective or curative option when risk is high or outbreaks are imminent, but they work best when used in combination with the other strategies and rotated to prevent resistance. Relying on a single tactic isn’t as effective: biological controls can help but aren’t usually the most reliable stand-alone option in turf; focusing only on irrigation management ignores other critical factors; and using just one fungicide while neglecting cultural practices can lead to poor disease control and resistance development.
