Soft rot decay in CCA treated eucalypts in Queensland - A comment

IRG/WP 1301

L E Leightley

A survey has been completed concerned with the distribution and severity of groundline soft rot decay in the CCA treated sapwood of eucalypt poles in Queensland. The survey encountered some 1000 poles of which 55% were slightly, 28% moderately and 17% severely decayed. Soft rot decay was more severe in urban than rural locations. Embedment of poles in concrete resulted in severe soft rot. No significant correlation was found between an increase in CCA retention and decrease in severity of soft rot. Soft rot decay was found to be very variable. Management of this variability could be made by practising realistic and efficient pole inspection techniques.
