Tips For Use
Restraints:
- Do not apply the product to steeply sloping sites when applying high rates recommended for perennial grass control.
- Do not allow spray drift onto susceptible crops and ornamentals.
- Do not spray near desirable trees.
Important:
- This product is very slow acting and control of existing growth will take 3-12 months depending on weather conditions and senescence of plant foliage. The actual length of satisfactory residual control will depend on soil type and rainfall until regeneration occurs from grass seed or surviving rhizomes. Rocky 745 Herbicide is liable to leaching and movement in the soil under heavy rainfall or irrigation, and dry conditions favour its persistence in the soil.
- Avoid use in channels and drains and where roots of desirable plants may extend; and in other situations where desirable plants grow close to the treated area.
- Control of grasses growing in shaded conditions may be reduced.
- Subterranean clover and other annual legumes may be damaged by this product if exposed to the spray or if they germinate before product residues have dissipated form the soil. Do not treat pasture land with this product more than once per year.
Mixing:
- This product is highly soluble in water and the required amount can be added directly to the spray tank while stirring or with the agitator running.
- When used in mixtures with dispersible powders, first make a slurry of the powder in a small quantity of water, add this to the half filled spray tank with the agitator running, and then add the required quantity of product and continue filling until the spray tank is full.
- Good agitation must be maintained during the spraying operation.
Wetting Agent:
- Addition of 100 mL of a non-ionic surfactant (600 g/L) per 100 litres of spray is recommended.
Compatibility:
- This product may be mixed with Glyphosate to improve knockdown of existing vegetation.
Application:
- Boom spray equipment should be carefully calibrated to deliver the required volume of spray and checked to see that the nozzles are delivering a uniform spray pattern.
Paddock Preparation:
- Graze to reduce cover of desirable species for spraying.
Re-Seeding:
- Desirable pasture species such as phalaris, cocksfoot, ryegrass, red and white clovers, subterranean clovers and lucerne may be sown after at least 100 mm of leaching rain has fallen.
- If drought conditions prevail defer sowing until next season.
Storage and Disposal:
- Store in the closed original container in a cool, well ventilated area.
- Do not store for prolonged periods in direct sunlight.
- Triple-rinse containers before disposal.
- Add rinsings to spray tank.
- Do not dispose of undiluted chemicals on site.
Safety Directions:
- Avoid contact with eyes and skin.
- Do not inhale spray mist.
- When preparing the spray wear elbow-length PVC gloves and face shield or goggles.
- If product on skin, immediately wash area with soap and water. After use and before eating, drinking or smoking, wash hands arms and face thoroughly with soap and water.
- After each day’s use, wash gloves and face shield or goggles and contaminated clothing.
First Aid:
- If poisoning occurs contact a doctor or Poisons Information Centre. Phone Australia 13 11 26.
- If skin contact occurs, remove contaminated clothing and wash skin thoroughly.
