Proposals for further co-operative studies on determining toxic values against wood-destroying Basidiomycetes
IRG/WP 2247

Document IRG/WP/2194 reported the status of the programme of co-operative experiments up to and including December 1982. During discussions at IRG-13 in Turkey members endorsed the decision to complete the programme of tests and conduct repeat tests. At IRG-14 in Brisbane the report was noted but no further action agreed. At IRG-15 in Sweden a number of interested parties in the European/Scandinavian area proposed that a further programme of work be established and that an informal project group be established. The agreed objective was to carry out co-operative tests essentially to refine the existing methodology currently preferred in Europe and used in support of long-established approval schemes. It was decided that the programme should take the form of a miniaturised wood block test with the objective of determining toxic values for specific fungicides and it should concentrate on approaches using sterile soil as well as pure cultures. Proposals submitted as Document No: IRG/WP/2237 were considered at Guaruja in May 1985 and approved with amendments. The present document presents the final proposals. This document aims to define the main test parameters. It is not a detailed specification of how to carry out the tests; where needed, practical guidance can be obtained from European Standard EN 113 (BS 6009:1982 and equivalent French and German versions) and the paper by Bravery in Document No: IRG/WP/2113 - Screening Seminar.
