Green and freshly felled poles have been treated by a simple method and cheap
chemicals. The equipment can be located very close to the site of felling and the
treatment can be carried out by semi-skilled workmen. An experiment was carried
out with this method on five indigenous wood species namely: garjan (Dipterocarpns
turbinatus), kao (Garceniacowa), jam (Syzygiuni grande), kalibatna (Qnerciisfenestrata)
and rai batna (Quercus thonisoni) with 10% copper sulphate solution at the felling site
of Chunati Forest Range, Chittagong. Analysis of the Results on the penetration and
the retention of the preservative inside the pole indicates that the entire portion of
the sap wood around the pole was completely penetrated and the required retention
was obtained.
