eFUME® ACTIVE is the active ingredient component of the eFUME® fumigation system, containing high-purity ethyl formate, a naturally occurring compound found in many foods and beverages. When used as part of the eFUME® system, it provides rapid and effective control of a broad range of insect pests across fresh produce, stored commodities, timber, and quarantine applications.
Developed to meet the evolving needs of modern agriculture and international trade, eFUME® ACTIVE offers a practical alternative to traditional fumigants by delivering effective pest control in significantly shorter treatment times while leaving minimal residues. Combined with carbon dioxide as a carrier gas, eFUME® enables efficient fumigation processes that support product quality, operational productivity, and compliance with domestic and international market access requirements.

Ethyl formate is one of the oldest fumigant chemistries known to science, with its insecticidal properties first documented in the early 1900s. Despite this early recognition, widespread commercial adoption was limited for many years due to challenges associated with application technology and gas distribution.
Interest in ethyl formate increased significantly as the agricultural industry sought alternatives to traditional fumigants. Advances in formulation, handling, and delivery systems enabled ethyl formate to transition from a promising research chemistry into a practical commercial solution. Today, it is recognised globally as an important fumigation technology, supported by extensive scientific research and regulatory approvals across a wide range of quarantine, phytosanitary, and post-harvest applications.
Its evolution reflects a broader shift within agriculture towards solutions that can maintain effective pest control while supporting product quality, operational efficiency, and the changing expectations of international markets.

INTRESO has developed and built the eFUME® Mix-Onsite System is a patented delivery technology that enables ethyl formate and carbon dioxide to be mixed immediately prior to fumigation.
By generating the fumigant blend on demand, the system eliminates the need to transport or store pre-mixed gas cylinders, providing greater flexibility and scalability for fumigation operations.
Designed for commercial fumigation environments, the Mix-Onsite System delivers consistent gas concentrations and efficient distribution throughout the treatment space.
