Dazomet is widely used as a soil fumigant in agriculture and horticulture to control a broad spectrum of soil-borne pests. It effectively suppresses nematodes, fungi, bacteria, weeds, and certain insects before planting crops. Commonly applied in fields, greenhouses, and nurseries, it breaks down in soil to release methyl isothiocyanate, the active agent responsible for its biocidal effects. It is especially valuable in the production of vegetables, fruits, and ornamental plants where pest-free soil is critical. Dazomet is also used for disinfecting soil in mushroom farming and can treat turfgrass areas to manage disease and weed issues. Its ability to penetrate soil makes it suitable for pre-plant bed treatment in both open fields and enclosed environments.
