Uptake of AuStar is most efficient when it is applied to soil which receives adequate water and where there is a high density of feeder roots. Apply required amount of AuStar in 0.5 to 2 Litres of water per tree onto the soil/trunk crack line evenly around the base of the trunk.
Where specific rates per tree are not given, the application rate per tree is determined by dividing the application rate per ha by the number of trees per Ha. The volume of diluted drench required for even application without runoff will vary with the size of the tree and with soil type and moisture content. Use the higher volume on larger trees.
Ensure that trees are adequately irrigated following treatment under dry conditions. Individual trees which are smaller than average should be left untreated or given a proportionally smaller dose of AuStar
Apply in a sufficient volume of water to ensure penetration of the spray and good coverage of target tissue, new green stem tissue in case of apples. Apply in a minimum volume of 1000 L of water per Ha. Surfactant (such as Agrol 600 or Wetspray 600) at 18 mL per 100 L of water must be added to the final spray volume. It is not normally necessary to re-apply the spray if rain follows soon after application. For best results, foliar spray after the sunset.
Apply in 200 to 300 mL water per tree beneath each trickle or dripper point. Follow application with a short period of irrigation. Alternatively, the required amount of AuStar can be applied through the trickle irrigation system. Equal distribution of water between trees is essential for this method to give a uniform effect.
In some cases, control of growth may persist for more than one year. Retreat trees when normal growth resumes. Use the interval between the first treatment and resumption of normal growth as a guide for retreatment in subsequent seasons.
AuStar is compatible with any one of the following products: Nimrod, Omite, Aphidex, Dithane or Mancozeb. However, mixing AuStar with more than one of these products may give unpredictable results or may result in crop damage. If Carbaryl is used as a thinning spray on apples, allow 21 days before application of AuStar
Storage and Disposal
Store in the closed original container in a dry, cool, well-ventilated area out of the direct sunlight. Triple rinse or preferably, pressure rinse containers before disposal. Add rinsings to spray tank. Do NOT dispose of undiluted chemicals on site. If recycling, replace cap and return clean containers to recycler or designated collection point. If not recycling, break, crush or puncture and bury empty containers in a local authority landfill. If no landfill is available, bury the containers below 500 mm in a disposal pit specifically marked and set up for this purpose clear of waterways, desirable vegetation and tree roots. Empty containers and product should not be burnt.
Avoid contact with eyes and skin. After use and before eating, drinking or smoking, wash hands, arms and face thoroughly with soap and water.
If poisoning occurs, contact a doctor or Poisons Information Centre.
