What is one of the recommended actions to control Large patch in warm-season grasses?

Aerification and dethatching are recommended practices for controlling Large patch in warm-season grasses because they improve soil aeration, water infiltration, and overall turf health. Large patch, caused by a fungal pathogen, thrives in compacted soils and areas with excessive thatch. By aerifying, you reduce soil compaction and create space for air and water to penetrate the root zone, which can help suppress the development of the fungus. Dethatching removes excess thatch, allowing for better air circulation and moisture management, both of which are critical in preventing the conditions that favor the growth of the disease.

Implementing these practices helps maintain a healthier lawn environment and reduces the likelihood of Large patch taking hold. Regular aerification and dethatching are part of an integrated pest management strategy that supports the overall resiliency of warm-season grasses against diseases.
