Methyl disulfide is widely used in the agricultural industry as a soil fumigant to control nematodes, weeds, and soil-borne pathogens. It is particularly effective in preparing fields for high-value crops like strawberries, tomatoes, and peppers. In the petrochemical sector, it serves as a sulfur source in refining processes and as an additive in lubricants to enhance performance. Additionally, it is employed in the synthesis of organic compounds, including pharmaceuticals and agrochemicals, due to its role as a building block in chemical reactions. Its strong odor also makes it useful as a warning agent in natural gas and other odorless gases for safety purposes.
