Technical note: Effects of 2,4-D and 2,4,5-T derivatives on bloodwood (Eucalyptus dichromophloia F. Muell.)

Abstract

Experiments were conducted on "Brian Pastures" Pasture Research Station, near Gayndah, in the Burnett River region, to test the effectiveness of 2,4-D and 2,4,5-T derivatives in destroying regrowth of bloodwood (Eucalyptus dichromophloia F. Muell.). This regrowth had occurred in trees that had been ringbarked but that had regenerated from the trunk below the frill or from lignotubers. Two methods were tested: (1) applying the herbicide to a frill and to the stumps of severed suckers; and (2) spraying the foliage with the herbicide.
