Alternative treatments are described in EPPO Standard PM 10/6 Heat treatment of wood to control insects and wood-borne nematodes and PM 10/8 Disinfestation of round and sawn wood with ionizing radiation. Specific approval and amendment First approved (as PM 3/51) in 2003-09. Revised in 2008-09. Introduction Round wood and sawn wood may be infested by a range of insects such as Scolytidae, Buprestidae and Cerambycidae. Such material serves as a pathway for the spread of the mentioned organisms. Several wood-related harmful insects are listed in the EPPO A1 and A2 lists as well as in the Alert list. Commodities/regulated articles Round and sawn wood without bark (wood dimensions should not exceed 200 mm cross section). Pests Wood related insect pests, e.g. Scolytidae, Buprestidae and Cerambycidae. Treatment schedule Treatment name: methyl bromide (CH3Br) fumigation at atmospheric pressure Temperature of wood Dose (g/m3) Minimum concentration (g/m3) at: 2 h 4 h 12 h 24 h 21°C or above 48 36 31 28 24 16°C or above 56 42 36 32 28 10°C or above 64 48 42 36 32 Efficacy of treatment The schedule is part of the ISPM No. 15 Guidelines for regulating wood packaging material in international trade (FAO, 2006). Notes • The minimum temperature should not be less than 10°C and the minimum exposure time should be at least 24 h • Monitoring of concentrations should be carried out at a minimum at 2, 4 and 24 h • It is recommended that the gas is circulated at the beginning of fumigation at least for 30 min to achieve gas uniformity over the wood material • Wood temperature should be the same as treatment chamber temperature • Available air space in fumigation chamber or tent should be at least 20% of the total volume • Wood dimensions should not exceed 200 mm cross section, otherwise the gas concentration and/or treatment time has to be adapted • Single wood pieces or logs have to be loaded in a way that gas is able to circulate: e.g. by using spacers between single boards Footnotes 1 The IPPC Recommendation Replacement or reduction of the use of methyl bromide as a phytosanitary measure (FAO, 2008) should be considered before using methyl bromide fumigation.
