New Zealand;

NZ EPA reviewed methyl bromide use and imposed restrictions of no emission beyond 2020. NZ is one of the largest users of methyl bromide for treating wood products exported to overseas countries. Hence, Stakeholders in Methyl Bromide Reduction (STIMBR) reviewed 15 chemicals and identified EDN as the only potential replacement for methyl bromide for the fumigation of logs exported. EDN efficacy studies are being conducted for the three main timber pests -Burnt pine longhorn Arhopalus ferus , Golden haired bark beetle Hylurgus ligniperda , Black pine bark beetle Hylastes ater . These pests constitute 99% plus of the surveillance, trapping and interception data in NZ. They are quarantine pests concern to importing country – China, India, South Korea, Japan and Australia. Extensive lab and field studies are being conducted by Plant and Food NZ using laboratory raised specimens. The studies will be completed in the beginning of Q1 2019 and will be provided to the training partners.


Malaysia is the leading producer of natural rubber in the world. About 46% of world rubber is produced in Malaysia. South American leaf blight disease is one of the deadly disease that is found in rubber which is reported in Mexico, Latin and South American countries. In order to protect the local rubber industry, Malaysian plant biosecurity has approved EDN for the treatment of all timber imported into the country. A dose rate of 100 g/m3 for 24 hours is approved for controlling this disease.

South Korea:

EDN is in the registration process for treating the wood products imported into the countries. It is expected to be approved in 2019.
