Intro to Ethyl Formate: The New Kid in the Toolbox

Benefits, Challenges, and the Path Forward Episode 5 of ATF introduces listeners to ethyl formate, branded as Efume, the first new postharvest fumigant in the United States in nearly seven decades. John B. Mueller lays the groundwork by explaining ethyl formate's origins, its chemical properties, and its approval process, emphasizing its unique status compared to conventional fumigants. Spencer Walsh, an expert in postharvest fumigation, provides historical context and discusses how ethyl formate stands out for its incredible efficacy against mites and other surface pests, especially in fresh fruit. The chemistry behind ethyl formate and its hydrolysis in moisture-rich commodities enables low residue concerns, leading to an EPA exemption from food tolerances—a key win for global trade and consumer safety. The conversation also touches on the operational advantages ethyl formate offers, such as portable application and alignment with regulatory demands for minimal residues. Both speakers caution that, despite its regulatory and consumer-friendly attributes, ethyl formate must be handled with strict safety procedures due to its flammable nature and potential risks. The episode concludes with a reminder to fumigators about the critical importance of monitoring concentrations and respecting all safety protocols as ethyl formate enters wider use in the industry.
