The influence of carrier fluid type on the efficacy of a wood preservative against cavity forming soft rot

IRG/WP 00-30244

P A Hodges

Propiconazole was applied to Scots pine sapwood (Pinus sylvestris) and beech (Fagus sylvatica) using three different carrier systems selected on their varying ability to swell timber. The effects of microdistribution on the activity of cavity forming soft rot fungi were examined to determine the practical benefits of using swelling and non-swelling carriers with this active ingredient. Efficacy of the active ingredient delivered by different carriers against micro-fungi was assessed using EN (V) 807 (1998). After exposure, the relative mean mass loss of the timber samples was used to measure the extent of decay.
