Abstract

In Korea, methyl bromide (MB) is limited to use for quarantine pre-shipment (QPS) treatment of imported timber and logs. Metam sodium (MS) is only fumigant to fumigate Japanese pine sawyer (JPS, Monochamus alternatus), which is well known main vector of pine wood nematode (PWN, Bursaphelenchus xylophilus) for the purpose of preventing the spread of PWN in Korea. However, MS fumigation requires high level dosage (1 L/m3) to control PWN. It has led to occupational health safety and environmental (OHS&E) issue and there are problems to reuse fumigated fresh pine log. There is an urgent requirement for development of fumigant to control JPS. Ethanedinitrile (EDN) showed fast penetrations into the timber, good efficacy on various wood pests. Therefore, we evaluated EDN as alternative to replace MB and MS for control of JPS. In this study, we reported more than 10 practical applications of EDN with different fumigation conditions since 2007 until 2013. The Ct (Concentration × time products) depending on different dose and conditions including fumigation types (plastic films: LDPE, tarpaulin, PVC-tarpaulin and metal container), water content of logs (18.8- 68.2%), filling ratio (5-50%), average temperature (5-16°C). The result shows that EDN have great potential for treatment of fresh pine wood logs to manage the JPS and its vector of PWN.
