Which statement best describes dollar spot management in warm-season turf?

• A. Maintenance relies solely on chemical fungicides.
• B. Combines reducing leaf wetness, proper fertilization, and preventive fungicides.
• C. Requires no cultural practices.
• D. Depends only on irrigation at night.

Answer: (B)

Dollar spot in warm-season turf is best managed with an integrated approach that reduces leaf wetness, maintains proper turf nutrition, and uses preventive fungicides. The disease thrives when leaves stay wet and the stand is stressed, so irrigation should minimize leaf wetness (water in the morning, avoid late or excessive watering) and cultural practices should keep the turf vigorous and well-balanced with appropriate fertilization. Preventive fungicides are used when conditions are favorable, applied before symptoms appear and rotated to prevent resistance. Relying on a single tactic misses the environmental and nutritional factors that drive the disease, and practices like night irrigation (which increases leaf wetness) or eliminating cultural practices altogether are not effective.
