Methodology of treatment of infested wood by spruce bark beetle (Ips typographus) using EDN(R) fumigation preparation
Stejskal, Václav ; Hnátek, Jonáš ; Kadlec, Jakub ; Aulický, Radek
The methodology describes the effective application of EDN(R) in the treatment of unprocessed wooden logs on heaps in forest. This methodology provides the technical and biological information regarding effective application of EDN(R) with the active substance ethanedinitrile in the treatment of harvested spruce logs in order to reduce the risk of spreading European spruce bark beetle (Ips typographus). The methodology describes technical specifications and the use of special application equipment for the application of the liquefied EDN from cylinders using nitrogen as an inert drive to treat harvested coniferous wood. The methodology is based on original experimental data. The general goal of the methodology was to help mitigate the current bark beetle calamity in the Czech Republic. The specific objectives of the methodology were to provide (i) objective and original information for the purposes of professional pest control staff and supervisory authorities (especially CISTA) on the method and procedure for treating wood using the EDN(R) product; ii) methodological documents necessary for repeated rapid preparation of the CISTA regulation for the use of EDN for the treatment of landfills under tarpaulin; and (iii) to provide a brief overview of published scientific information and an evaluation of the methods and preparations used for phyto-quarantine treatment of wood against European spruce bark beetle (Ips typographus) in comparison with the new procedure described in this methodology (i.e. EDN-fumigation of piles of spruce-logs under a plastic sheet).
