Field trials of groundline remedial treatments on soft rot attacked CCA treated Eucalyptus poles
W S McNamara, R J Ziobro, J F Triana
A total of 17 CCA treated Eucalyptus poles, which were found to contain 2-5 mm of soft rot in October, 1980, were reinspected in October, 1982. In 1980, 11 of the poles were given a supplemental groundline bandage treatment of either Osmoplastic or Patox, while 6 of the poles were designated as untreated controls. Two years after remedial treatment, samples were removed from the poles for microscopic observations and for chemical retention analysis. It was found that the remedial bandage treatments were effective in preventing any further advance of soft rot. Based on the positive results of this study, a treatment efficacy of five years or longer is predicted.
