Stem Injection Application

DILUTION RATE: Mix one part Tordon RegrowthMaster with four parts water.

AGRICULTURAL NON-CROP AREAS, COMMERCIAL AND INDUSTRIAL AREAS, FORESTS, PASTURES AND RIGHTS-OF-WAY
WEEDS CONTROLLED WEED GROWTH SIZE STATE APPLICATION RATE CRITICAL COMMENTS
Acacia, angophora, casuarina, corymbia, eucalyptus (except yellow box), lophostemon and melaleuca species and camphor laurel. Single stems less than 25 cm diameter at base (waist height application). All states 1 mL of diluted chemical per cut @ 10 to 13 cm centres. NOTE: Control of casuarina and lophostemon species may be variable. Use ground level application to reduce variability.
  Single stems less than 25 cm diameter at base (ground level application).   1 mL of diluted chemical per cut @ 12 to 15 cm centres. DO NOT exceed the spacings shown from the centre of one cut to centre of the next cut. Inject each stem of a multistem tree where possible.
  Multiple stems or more than 25 cm diameter at base (waist height application).   2 mL of diluted chemical per cut @ 10 to 13 cm centres. Injection at or near ground level is essential in the Traprock area of southeastern Queensland and is preferred for optimum results in poplar box areas.
  Multiple stems or more than 25 cm diameter at base (ground level application).   2 mL of diluted chemical per cut @ 12 to 15 cm centres. In areas where experience has shown that results are variable because species are harder to kill or due to marginal soil and/or climate factors, higher doses may improve control.
