GENERAL INSTRUCTIONS

Mixing: Mix only with water. It will not mix with oil or diesel fuel. Mechanical or by-pass agitation in the spray tank is recommended and it should be maintained during spraying. Quarter fill the spray tank and add the required amount of herbicide in the following order: Wettable powder or water dispersible granules; suspension concentrates (atrazine flowable); aqueous concentrates (e.g. KELPIE 2,4D PICLORAM FALLOW HERBICIDE, 2,4-D Amine); emulsifiable concentrates and finally surfactant or crop oil.

APPLICATION

KELPIE 2,4D PICLORAM FALLOW HERBICIDE may be applied by:
Ground boom. Spray using accurately calibrated equipment delivering 50 – 100 L water/ha. DO
NOT use less than 200 L/ha in sugar cane. When treating maize and sorghum, the risk of crop injury will be reduced if dropper nozzles are used to avoid spraying the growing point of the crop. Misting machines and boomjet sprayers should not be used for treating crops.
Aircraft. Use accurately calibrated equipment to deliver not less than 20 L water/ha. DO NOT use less than 50 L/ha in sugar cane.
High volume. Apply using a calibrated handgun with D5 or D6 (2 – 3 mm) nozzle plate and operated at 400 – 500 kPa. Spray to thoroughly wet the weed, usually 2,500 – 3,500 L water/infested ha is required.
Stem injection. Treat only trees with good sap flow. Make injection cuts at 13 cm spacing around the diameter of the tree at waist height or at 15 cm spacing at ground level. The cuts should be made using a 5 to 7 cm wide narrow bladed axe. The cut must be made through the bark and deep enough to place all the chemical in contact with the sap wood. Treat each stem of a multistem tree where possible. Inject the chemical mix into each cut immediately after the cut is made. Apply the mix with a vaccinator or similar equipment which can be accurately calibrated or a tree injector which can apply the measure dose at or near ground level. Injection at or near ground level is essential in the
Traprock area of south-eastern Queensland and is preferred for optimum result in Bimble box (poplar box) areas.
Cut stump. Cut the trees as close to the ground as practicable, leaving stumps no higher than 10 cm.
Spray, swab or brush the chemical mix immediately to the freshly cut surface so as to thoroughly wet the surface. If the cut surface is oily, add a non-ionic wetting agent to assist penetration. Frilling. Make successive overlapping cuts into the sapwood around the entire circumference of the
 base of the tree. Spray to thoroughly wet the frilled area. Injecting spray into centre of weed. Inject using a vaccinator or similar equipment. 1 mL of treatment mix into the growing point for each 2.5 cm of the plant stem diameter. (See Zamia palm).
