EDN™ fumigant (C₂N₂ ) is a rapid-acting, volatile, colourless flammable chemical used for fumigation of soil prior to planting certain crops and in the timber industry to control various insect pests and pathogens, nematodes, and weeds. EDN™ is not a new molecule. It was discovered in 1815 but was not manufactured on a large scale until the late nineteenth century. EDN™ is used in other industries for various purposes. It has been introduced into the fumigation market as a viable and non-Ozone depleting alternative to the now commonly banned Methyl Bromide. Although it has toxic qualities, it is safe to use when applied in controlled environments as per regulatory standards, which apply to all fumigants. It can be applied by different methods to different commodities. EDN™ is registered for commercial use in Australia, with many other countries’ registration pending.
