Sulfuryl fluoride is a broad-spectrum fumigant pesticide. The pesticide was registered for the first time in the United States in the 1950s. However, it has only been used as a food (grain) fumigant for more than a decade internationally. This is mainly because its problems are prominent, and it has been a controversial fumigant from the start. At present, “reducing the dose of pesticides, reducing residues, and reducing emissions” is an inevitable requirement for the development of sulfuryl fluoride fumigation and insecticide technology. The research and development of sulfuryl fluoride efficient fumigation and insecticide technology featuring “low dose, low residue, and low emission” is likely to be a feasible technical approach.
