Stem Injection Application: Make horizontal cuts with a narrow-bladed axe (5–7 cm wide) through the bark of the woody weed into the sap stream at waist height. Space these at 10–13 cm centres. Leave the axe in the cut and immediately (within three seconds) apply the herbicide down the axe blade, to ensure the full dose enters the sap stream. This is necessary because the plant can seal the cut quickly, thus barring the chemical penetrating into the sap stream. Do not treat trees with poor sap flow, which occurs when plants are stressed. Where low branches are encountered place a cut immediately below the branch.
Cut Stump Application: Cut stump application is the preferred method for saplings that are too small to be stem injected. Cut stems as close to the ground as practical, no higher than 10–15 cm from ground level. Thoroughly apply the herbicide mixture or gel immediately after the cut is made. This is necessary because the plant can seal the cut quickly, thus barring the chemical from penetrating into the sap stream.
Foliar Spray Application: This method normally refers to high volume application using a handgun to treat the foliage of the plant. It is recommended to use a No. 5–8 tip on your gun and calibrate your pump pressure to 700–1500 kPa. Ensure you treat the entire leaf area of the plant to the point of run-off, with thorough coverage of the crown, runners and tips. Knapsack and 12-volt sprayer packs are only recommended for the control of herbaceous weeds such as cobblers peg, docks and wandering jew.
