A non-selective water soluble herbicide for control of a wide range of annual and perennial weeds in a wide variety of situations as per the Directions For Use Table.

PROTECTION OF CROP, NATIVE AND OTHER NON-TARGET PLANTS:
DO NOT apply under weather conditions, or from spraying equipment, that may cause spray to drift onto nearby susceptible plants/crops, cropping lands or pastures.
DO NOT allow spray to contact any part of desirable plants.
DO NOT use prior to transplanting tomato seedlings.
There is no withholding period for this product but removal of stock may be necessary to achieve efficacy. It is recommended that stock be removed from the area to be treated for 1 day after treatment of annual weeds and for 7 days after treatment of perennial weeds.
Certain plants (eg Soursob, Variegated Thistle) may be naturally toxic to stock. Where known toxic plants are present, do not allow stock to graze until complete browning of treated plants has occurred.

DIRECTIONS FOR USE:
RESTRAINTS:
DO NOT spray if rainfall is expected as rainfall within 6 hours of treatment may reduce the effectiveness of the product. Heavy rainfall within 2 hours of treatment may wash the product from the leaf surface and retreatment may be necessary.
DO NOT disturb treated weeds by grazing, cultivation, sowing, etc after treatment for 1 day for annual weeds, and 7 days for perennial weeds to ensure complete uptake of the herbicide.
DO NOT apply to weeds under stress from frost, cold, disease, waterlogging or lack of moisture. Plants must be actively growing to ensure optimum uptake of the product.

GENERAL INSTRUCTIONS
Mode of Action
Allout 450 Herbicide is a water-soluble liquid herbicide. The product is non-selective and will control a wide range of emerged annual and perennial weeds. It provides no residual activity and is inactivated once it comes in contact with the soil. The product is absorbed by plant leaves and green stems and is then translocated throughout the plant to the root system. The product inhibits a plant enzyme causing a breakdown in the metabolic pathway leading to death of the plant. Visual effects of product efficacy are gradual wilting, yellowing leading to complete plant browning. For annual weeds, effects are usually apparent in 3 to 7 days and for perennial weeds up to 14 to 21 days. The time taken for these effects to appear will vary depending on the speed of translocation which will be dependent on climatic conditions such as temperature, moisture conditions etc. Best results are obtained if plants are sprayed when they are actively growing and not under any stress from such factors as disease, waterlogging, insect damage, drought stress etc. To ensure that the product is adequately absorbed by weeds it is recommended that spraying be delayed if rainfall is expected. Rain up to 6 hours after application may reduce the efficacy of the product and heavy rain within 2 hours may necessitate re-treatment. Plants which are covered in dust or which are wet with dew should not be treated.
Crop Establishment:
Where the product is used to control weeds prior to the establishment of a new crop or pasture it is important that the crop or pasture not be sown until a suitable seed bed is present. Where a light cover of weeds has been sprayed, it may be possible to sow in one day. Where a large amount of dead weed matter or trash is present the seedbed needs to be adequately prepared before crop or pasture sowing. 

MIXING AND APPLICATION
Allout 450 Herbicide may be applied by boom spray, air, knapsack, handgun or wiper application.
Boom Application: Spray volumes of 25 to 100 L water/ha recommended with a fan nozzle at pressures of 240 to 280 kPa. Boom height must be set to ensure double overlap of spray patterns at the top of the weed canopy.
Wiper Application: (e.g. ropewick, canvas, carpet or felt applicators) may be used to apply the product in the situations as per the directions for use table. Weeds should be at least 15 cm above the crop and the wiper equipment should be operated at least 10 cm above the crop. Best results are obtained with lower speeds of application (do not exceed 8 km per hour) and where two applications are made in opposite directions ie. double pass. Where herbicide does not contact foliage (due to different levels of foliage) results may not be satisfactory and re-treatment may be required. Do not store a mixed solution for more than 2 days. Rate: 800 mL of product to 2.2 litres of water.
Aerial Application: Apply a minimum spray volume of 20 L/ha for micronair and boom equipment. Droplet size should be 250 to 350 microns and the swath width 15-17 metres. Aerial application is only recommended in pasture or fallow situations before establishment of a new crop or pasture or in pre-harvest sorghum. On sloping ground, the spraying height may vary, so it is recommended that the spray volume be increased to 30 to 80 L/ha with a droplet size of at least 300 micron. Since the product is nonselective it is important to avoid spraying in conditions likely to cause drift. e.g. wind over 8 kph, temperature inversion, still air and hot dry days.
DO NOT use in intensive horticultural areas. Use recommended rates specified in this label to a maximum of 3.2 L/ha.

APPLICATION IN HOT CONDITIONS:
When the temperature reaches 25 C increase the water volume to at least 30 L/ha and droplet size to a least 300 micron VMD to compensate for additional evaporation of sprayed droplets. DO NOT use by air in temperatures above 30 C.
Surfactant
The addition of surfactant may improve weed control where water rates are high or product rates are low. Suggested surfactant rates are 200 mL/100 L of 1000 g/L nonionic surfactant or 250 to 500 mL of 700 g/L surfactant. Do not add spraying oils, agricultural chemicals or any other material except as directed on the label.

Mixing - When the product is to be mixed with water it is important that clean water be used. Dirty water or hard water containing calcium salts may reduce the product's effectiveness. The following procedure for mixing should be followed:
1. Ensure spray tank is clean and that previous chemicals used are washed from the tank.
2. Half fill the tank with clean water, add the required amount of Allout 450 Herbicide.
3. Add the rest of the water.
4. Add surfactant last.

Compatibility: The product may be mixed with a variety of products to enhance weed control to broaden the spectrum of weeds and to add residual control. Refer to the "Directions for Use" Section for detailed information on the tank mix situations.

Additives: Crystalline Ammonium sulfate assists in minimising antagonism when mixed with flowable Triazine herbicides. The only form of Ammonium sulfate to be used is the crystalline form (not prilled or granule forms). Test the quality by dissolving 2 tablespoons in 2 litres of water. Swirl gently for 2 minutes. Should undissolved particles still remain at the end of that time, pre-dissolve them prior to adding product to spray tank. Ensure solution is poured through a screen.

Herbicides: Atrazine - flowable or granular (see additives above - do not apply the tank mix for control of barnyard grass or liverseed grass), Dicamba, 2,4-D ester, Express, chlorsulfuron, metsulfuron, Yield, Stomp, Logran, LVE MCPA, Goal CT. Goal CTThe addition of Goal CT at 75 mL/ha to recommended rates of this product prior to planting Wheat or Barley will improve knockdown and increase the speed at which treated weeds develop visible symptoms of phytotoxicity. Add Flowright Compatibility agent to improve the compatibility in cold water. (Less than 15 C). See directions below.

Insecticides: Chlorpyrifos, Dimethoate, Fenitrothion, Gusathion, Imidan, le-Mat, Lorsban, Metasystox, Sumithion, Perfekthion EC400.

Flowright compatibility agent
Rate: 200 mL/100 L spray solution. When mixing with Goal CT, add to improve the compatibility in cold water (less than 15 C) Flowright must be premixed with Goal CT before adding to the spray tank. Refer to Flowright label for full directions.
For tank mixing the following procedure should be undertaken:
1. Half fill tank and start agitator.
2. Add crystalline ammonium sulfate (if required) through mesh screen.
3. Add companion product.
4. Add Allout 450 Herbicide and rest of the water.
5. Add surfactant and maintain agitation while spraying.

Equipment Maintenance and Usage: Allout 450 Herbicide should ONLY be stored, mixed or applied in plastic or plastic lined, stainless steel, aluminium, copper, brass or fibreglass containers. The product and spray solutions react with galvanised steel and unlined steel tanks and containers to form hydrogen gas which form a highly combustible gas mixture. This gas could cause an explosion if ignited by an open flame. All application equipment including tanks, nozzles, hoses, aircraft and aircraft landing gear, should be thoroughly washed after use to prevent corrosion.
