Description
The response of native pastures after stem injection of eucalypt woodlands with picloram-triclopyr herbicide in 1986 was Investigated at 2 locations in Queensland over 18 months, Treatments were fenced to exclude half the plots from grazing by cattle. At Rolleston (good rainfall) dry matter grass response from grazed and ungrazed plots was 2- to 3-fold more than in untreated plots 4-18 months after treatment. At Mundubbera (low rainfall) picloram-triclopyr gave 2- to 5-fold increases in grass dry matter 3-18 months in ungrazed plots and 3-9 months in grazed plots. At both sites plclorarn-triclopyr gave quicker nnd greater grass response than hexazinone. Rate evaluation trials conducted in 1982 established tebuthiuron efficacy on brigalow (Acacia harpophylla) regrowth and associated woody plants in Queensland. Pasture response, as assessed by the BOT ANAL method 17 and 27 months after treatment, gave a 3- to 5-fold increase over untreated.
