Used as a soil fumigant in agriculture to control nematodes, insects, and certain fungal pathogens in crops such as vegetables, fruits, and ornamental plants. Commonly applied in seedbeds and greenhouse soils to protect young plants from root damage. Effective in pre-planting treatments, especially in high-value crops where nematode infestation poses a significant threat. Its action helps improve root health and crop yields by reducing pest pressure in the rhizosphere.
