The evaluation of permethrin for wood preservation
1977 - IRG/WP 3107
The toxicity of the synthetic pyrethroid permethrin (NRDC 143) to a range of wood destroying insects has been investigated. In tests using Hylotrupes bajulus, Anobium punctatum, Lyctus brunneus and Reticulitermes santonensis permethrin showed a similar order of toxicity to that of gamma-BHC. Although the toxicity of permethrin to adult Anobium punctatum was of the same order as that of gamma-BHC, ...

Marine test of synthetic pyrethroids at Sekondi, Ghana
1981 - IRG/WP 478
The trials reported here are part of a new series of marine exposure tests (Ghana Series 80) begun in October 1979 and designed to assess the natural durability if indigenous timber species and the performance of preservatives and preservative combinations in indigenous wood substrates in Ghana's coastal waters....

The influence of formulation on the behaviour of LOSP's during industrial impregnation of spruce
1986 - IRG/WP 3387
Evidence is presented that the comparative behaviour of two LOSP formulations during impregnation treatment of spruce cannot be predicted purely on the basis of their physical characteristics (viscosity, surface tension and contact angle) nor on the extent of their 'passive' penetration into pine sapwood....

Volatile losses of wood preservatives
1973 - IRG/WP 236
The purpose of the work we have undertaken so far has been to try to quantify the volatile losses which occur in treated timber, and to examine some of the factors which influence these losses. The preservative compound chosen for the initial part of the programme was the contact insecticide g-BHC. This was attractive for several reasons, not the least of which was that specific and sensitive anal...

The effect of synthetic pyrethroid insecticides on post-treatment emergence of Anobium punctatum
1992 - IRG/WP 92-1568
Data is presented from trials in which wood specimens, treated with a range of remedial insecticidal formulations, were aged in a roof void for 5 years and then tested for emergence of adult Anobium punctatum. The technique used followed that described in IRG/WP/2175. The results from formulations containing synthetic pyrethroids are compared with those from formulations containing the chlorinated...
