GENERAL INSTRUCTIONS
Uni-Star Selective Herbicide is a water dispersible granular, herbicide for the pre-plant, incorporated by sowing, control of annual ryegrass, paradoxa grass and certain broadleaf weeds in wheat, and for post-emergent control of wild radish in wheat, oats and barley.
Crops other than wheat, barley, oats, triticale and cereal rye can be very sensitive to low soil concentrations of Uni-Star Selective Herbicide, thus prior to using the product, careful consideration should be given to crop rotation plans.

Mixing
Uni-Star Selective Herbicide is a water dispersible granular herbicide which mixes readily with water and is applied as a spray.
- Partly fill the spray tank with water
- Start the agitation
- Add the correct amount of product to the spray tank with the agitation system running.
- Continue agitation while topping up the tank with water and while spraying.
- Use the spray mix within 24 hours of preparation.
Application
Ground Application
Apply by boom spray, applying 30 to 100 L of water per hectare.
Avoid overlapping of boom runs.

Aerial application
Always spray in a cross wind of less than 5 knots. Ensure good spray coverage is obtained.
Apply 20 to 40 litres per hectare.
Sprayer Cleanup
When the sprayer is being used to spray cereal crops, rinse the sprayer thoroughly with water.
Where the sprayer is being used to spray crops other than cereals:
1. Drain tank and rinse tank and spray boom with clean water for at least 10 minutes.
2. Fill the tank with clean water and add to it 300 mL of household chlorine bleach (containing 4% chlorine) per 100 L of water. Rinse hoses and boom and leave in tank for 15 minutes whilst agitating. Drain through nozzle.
3. Repeat step 2 and then rinse thoroughly with clean water to remove all traces of chlorine bleach.
4. Nozzles and filters should be cleaned separately.
5. Dispose of all water used for cleaning.
Compatibility
When using a tank mix of Uni-Star Selective Herbicide and Spray Seed, add Uni-Star, with constant agitation, to approximately half the total volume of water to be used.
Ensure that the Uni-Star is fully dispersed.
Add the Spray Seed, fill the spray tank to full volume with water and mix thoroughly.
Apply tank mix immediately, under constant agitation.
Uni-Star Selective Herbicide is compatible with Metolachlor 720, Tri-allate, Spray Seed, Glyphosate, sodium molybdate, zinc sulphate, manganese sulphate, copper sulfate, 2,4-D Amine, Metsulfuron-methyl, chlorpyrifos, permethrin, bromoxynil and trifluralin.

Precautions
Some crop yellowing or crop retardation may occur where stress factors such as water logging, drought, excessive soil acidity or alkalinity, nutrient deficiency or trace element deficiency disease - rhizoctonia, Take All, cereal cyst nematodes, or soil insects are present or occur following application. Special care should be taken with regard to the application of Uni-Star Selective Herbicide to durum wheats as these may be more sensitive where the above stresses are present. In these situations crop recovery will be rapid provided stress factors do not continue exerting a negative effect on the crops growth.
Crop retardation may also occur in some instances where considerable late summer/early autumn weed growth occurs. Weeds such as goosefoot Chenopodium spp can release herbicidally active compounds into the soil.
Re-Entry Period
DO NOT enter treated area without protective clothing until spray has dried.
