• Use Description: Disulfuryl fluoride, which was discontinued from stock on April 10, 2000, had several applications in various fields prior to its discontinuation. In the agricultural industry, it was used as a fumigant to control pests and insects in stored grains and agricultural commodities, playing a vital role in pest management and ensuring the quality of stored crops. Additionally, in the field of structural pest control, it was employed for termite eradication and control, protecting buildings and structures from termite damage. Its effectiveness as a fumigant made it valuable in maintaining food and structural integrity. However, it was discontinued likely due to environmental and safety concerns associated with its use, highlighting the importance of continually evaluating and improving chemical practices in these fields.
