Used as a fungicide in agriculture, particularly for the control of fungal diseases in stored potatoes. It prevents the growth of mold and other fungi during storage and transport, helping to extend shelf life and reduce crop losses. Applied as a post-harvest treatment, it is typically sprayed or fogged in storage facilities. Also used to protect onions and other root vegetables from fungal decay. Its vapor action makes it effective in enclosed spaces where air circulation can distribute the active ingredient evenly.
