Which management practice is NOT listed as important for brown patch control?

• A. Proper fertilization
• B. Proper irrigation
• C. Proper air circulation
• D. Regular mowing

Answer: (D)

Brown patch tends to develop when warm, moist conditions create a thick, wet canopy that favors the pathogen. The most effective management actions target the factors that directly influence that environment: nutrition, moisture, and airflow around the turf. Using proper fertilization helps avoid lush, dense growth that is easily infected, while careful irrigation prevents leaves from staying wet for too long. Improving air circulation around the turf reduces humidity buildup and slows pathogen activity. Regular mowing is a good general turf practice for health and appearance, but it doesn’t directly address the conditions that drive brown patch, so it isn’t listed as a primary control measure. In practice, balance mowing as part of overall turf care, while emphasizing appropriate fertilization, irrigation, and air circulation to control the disease.
