Abstract
Results of long-term evaluation of several indigenous methods for protection of underwater
timbers against wood boring organisms are reported in this paper. While unprotected
control poles were totally destroyed due to severe infestation by the wood borers
within a period of 9 months, the poles covered with coppcr-crome-arscnic (CCA)/ creosote
fuel oil (CFA) treated coir rope lasted for 5 years, the ones studded with iron nails gave
a life of 16 years and those plastered with cement over CCA treated coir rope winding/
scattered nailing interconnected with winding wire were in sound condition even
afterwards. Specific advantages offered by the methods in curtailing marine borer attack
arc also mentioned.
