Protection of freshly felled timber against attack by bark boring insects

IRG/WP 1143

J Dominik, P R Skidmore

This report describes two experiments with the insecticide formulation Perigen, which contains the synthetic pyrethroid permethrin. At 0.2% w/v active ingredient individual logs were protected against bark boring beetles for 18 weeks. At 0.3% w/v active ingredients Perigen gave similar protection against insect attack to stacks of recently felled unbarked pine logs. This protection was at least equivalent to that obtained with a 5% w/v aqueous DDT emulsion.
