Advances in control of woody weeds in radiata pine plantations in Victoria.  D. W. Flinn and G. Minko.  November 1981.  7 pp. (unpubl.)

SUMMARY

Methods used by the Forests Commission Victoria (FCV) to control regrowth of silver wattle (Acacia dealbata Link) and eucalypts (Eucalyptus spp.) in young plantations of radiata pine (Pinus radiata D. Don) are discussed. Recent advances in woody weed control are outlined and results of two field experiments presented.

It was shown that 3, 6-dichloropicolinic acid and hexazinone are promising herbicides for control of the target species, especially if applied at an early stage of weed development (< 1 m tall). Results indicated that liquid hexazinone is more effective than the granular form when broadcast at equivalent application rates, and that efficacy of liquid hexazinone may be improved by the use of petroleum oil in the carrier.
