What is the function of soil fumigation in turf management?

• A. To provide nutrients to the soil
• B. To create more sunlight for the grass
• C. To form a gas that controls existing plants and pathogens
• D. To aerate the soil for better drainage

Answer: (C)

Soil fumigation plays a crucial role in turf management by utilizing volatile chemicals that create a gas designed to control existing plants, pests, and pathogens within the soil. This method is particularly effective because the gas can penetrate the soil deeply, reaching areas that are often difficult to access with other forms of pest and disease control. By effectively reducing populations of harmful microorganisms and pests, soil fumigation helps to enhance the overall health of the turf, facilitating better growth and establishment of grass species. While nutrient provision, sunlight creation, or soil aeration are beneficial to turf management, they do not accurately describe the primary function of soil fumigation. Nutrients are typically added through fertilization, sunlight is naturally available and cannot be artificially created by fumigation, and soil aeration is a mechanical process aimed at improving drainage and promoting root health, which is unrelated to the purpose of fumigation. Thus, understanding the unique role of soil fumigation in controlling soil-borne threats is essential for effective pest management in turfgrass systems.
