To help control Red Thread, which measures are recommended?

• A. Nitrogen fertilization and watering will help control this disease
• B. Fungicide only
• C. Drought stress
• D. Potassium deficiency

Answer: (A)

Red Thread thrives when the turf has low nitrogen and experiences moisture stress. The best way to control it is to boost the turf’s nutrition and keep soil moisture at a steady, appropriate level. Applying nitrogen fertilizer improves tissue nitrogen content, color, and density, helping the grass outgrow the disease and recover more quickly. At the same time, providing adequate watering avoids drought stress, which can make grasses more susceptible to Red Thread and helps prevent the leaf conditions that favor the fungus. While fungicides can be part of a control plan in some cases, addressing nutrition and moisture is the most effective, long-lasting approach for this disease. Drought stress and potassium deficiency aren’t primary drivers of Red Thread, and relying on those factors would not help control it.
