Safe and high efficient method for application of liquid ethyl formate (FumateTM) to replace methyl bromide for treatment of imported nursery plants

There have been significantly increased reports of finding invasive quarantine pests with increasing import plants into Korea. Moreover, the efficacy and work safety issues have been reported regarding use of methyl bromide (MeBr) for fumigation of imported nursery plants. For replacement of MeBr use on imported plants, a new technology of using liquid ethyl formate has been registered in South Korea as FumateTM. The technology involved to mix ethyl format with nitrogen gas to form non-flamable ethyl format formulation. It has been evaluated on various imported plants. The FumateTM is recently developed and commercialized in Republic of Korea and Australia for quarantine treatments on fresh fruits, grains etc. Fumigation with FumateTM offers environmental-friendly and practically safe use of liquid ethyl formate. We have extended the use of liquid EF application technology to quarantine treatment of imported nursery plants.
