DIRECTIONS FOR USE
RESTRAINTS
DO NOT disturb treated weeds by cultivation, sowing or grazing for 1 day after treatment of annual weeds and 7 days for perennial weeds.
DO NOT treat weeds under poor growing or dormant conditions such as occur in drought, water logging, disease, insect damage or following frost. Reduced control may also occur when treating weeds heavily covered with dust or silt.
Rainfall occurring up to 6 hours after application may reduce effectiveness. Heavy rainfall within 2 hours of application may wash the chemical off the foliage and a repeat treatment may be required.
DO NOT use prior to sowing tomatoes.

AQUATIC WEED CONTROL

| SITUATION | WEED | CRITICAL COMMENTS |
| :--- | :--- | :--- |
| AQUATIC AREAS For the control of emerged weeds in all bodies of fresh and brackish water which may be flowing, non-flowing or transient. Also for weeds on margins of streams, lakes and dams and in channels and drains | For specific rates of application refer to the Aquatic Weeds Table below. | Reduction in effectiveness may result if more than 1/4 of the above ground portion of the weed is submerged at treatment. Submerging the treated plants following treatment may result in the spray being washed from the plant surface, thus reducing effectiveness. DO NOT apply this product within 0.5 km up-stream of potable water intake in flowing water (ie river or stream, etc) or within 0.5 km of a potable water intake in a standing body of water such as a lake, pond or reservoir. Applications to moving bodies of water should be made while travelling upstream wherever possible to prevent concentration of this herbicide in water. When making any bankside applications, DO NOT overspray more than 0.5 m into open water. Avoid spraying across moving bodies of water, or where weeds DO NOT exist. When spraying floating weeds, use a low volume, low pressure boom sprayer, CDA or sprinkler sprayer. DO NOT submerge the weeds when spraying as this may wash the herbicide off the leaves. When emerged infestations require treatment of the total surface area of impounded water, treating the area in strips may avoid sudden impact on habitat. |

This product does not provide residual weed control. Permanent water and approved selective herbicides should be used to provide continuing control of weeds. |

NOT TO BE USED FOR ANY PURPOSE, OR IN ANY MANNER, CONTRARY TO THIS LABEL UNLESS AUTHORISED UNDER APPROPRIATE LEGISLATION.
WITHHOLDING PERIOD: NOT REQUIRED WHEN USED AS DIRECTED

GENERAL INSTRUCTIONS
This product is a non-volatile, water soluble liquid with non-selective herbicidal activity against many annual and perennial broadleaf weeds and grasses. This product may be used for weed control in agricultural land prior to sowing any edible or non-edible crop, but not prior to transplanting tomato seedlings. This product is absorbed by plant foliage and green stems. It is inactivated immediately in the soil and does not provide residual weed control. This product moves through the plant from the point of contact and into the root system. Visible effects on annual weeds take 3-7 days, but on perennial weeds may not be obvious for 2-3 weeks or longer in some cases.
Visible effects of control may be delayed by cool or cloudy weather at and following treatment. Visible effects are a gradual yellowing and wilting of the plant which advances to complete browning of above ground growth and deterioration of underground plant parts. Delay application until vegetation has emerged to the stages described in the “Weeds Controlled” tables. Unemerged parts arising from attached underground rhizomes or root stocks of perennials will not be affected by spray and will continue to grow. For this reason best control of most perennial weeds is obtained at late growth stages approaching maturity.

Crop Establishment
This product is recommended for control of emerged weeds prior to crop establishment. Suitable cultivation and/or sowing operations are required to provide seedbed conditions satisfactory for crop germination and development.
Spraying early to control young weeds will favour preparation of suitable seedbeds. On friable soils and where there is only light cover of young weeds, sowing may proceed satisfactorily from one day after spraying.
In situations of heavy weed growth sowing should be delayed until weed decay and soil conditions allow formation of a satisfactory seedbed. Incorporation of green or decaying vegetation and roots into seedbed by cultivation or sowing may cause retarded crop emergence, particularly in cold and/or wet conditions. Vegetation may be reduced by grazing, and weed decay may be assisted by cultivation to leave trash on the surface. In marginal seedbed conditions take care to achieve correct seeding depth, and avoid use of pre-emergence herbicides where label directions advise risk of retarded crop emergence.

Mixing Instructions
This product mixes readily with water. Reduced results may occur if water containing soil is used, eg. water from ponds and unlined ditches, or if hard water containing calcium salts is used. Ensure the spray tank is free of any residue of previous spray materials.
Fill the spray tank with one half the required amount of clean water and add the proper amount of this product. Mix well before adding the remaining portion of water. Placing the filling hose below the surface of the spray solution will prevent excessive foaming. Removing hose from tank immediately after filling will prevent back siphoning into water source. DO NOT use mechanical agitators as these may cause excessive foaming.
For mixing instructions for tank mixes, see Tank Mixtures

Tank Mixtures
This product may be tank-mixed with the following herbicides, insecticides and additives where recommended. Read and follow all label directions, restraints, plant-back periods, withholding periods and safety directions for the tank mix products.
Instructions for the mixing of additional products
1. Fill the spray tank 1/3 to 1/2 full with clean water and start agitation.
2. Add recommended herbicide/ insecticide/ additive to the spray tank and mix thoroughly.
3. Where ammonium sulphate is recommended, add Liase at a rate of 2 L/100L spray solution and mix thoroughly.
4. Add weedmaster® DUO and the remaining water. Mix thoroughly.
5. Add surfactant, if required, near the end of the filling process to minimise foaming.
6. Always maintain adequate agitation during application and use the tank mix promptly.

Tank mixtures - Herbcides
Atrazine Hi-Load 600Ψ and 900DF (DO NOT apply the tank mix for Barnyard grass control), Estercide® Xtra 680, Grunt® WDG 750¥ (ensure mixture includes Liase first), Kamba® 500 (dicamba), Glean*/Lusta®, Simazine flowableΨ and 900DF, Oust*, Yield*, Rifle® 440, Stomp* 330 (pendimethalin), Nufarm Surpass®, Ally*/Associate®, Logran*/ Nugran, Flandor* 500, LVE MCPA and Striker®.
The addition of Striker at 75mL/ha to recommended rates of weedmaster® DUO prior to planting wheat or barley will improve knockdown and increase the speed at which treated weeds develop visible signs of phytotoxicity. Mixture requires a specific compatibility agent. Seek advice.
ΨAdd ammonium sulphate as per directions below.

Tank mixtures - Additives
Ammonium Sulphate: Add Liase to water first at a rate of 2 L/100L spray solution. (DO NOT apply the tank mix for Barnyard grass control).
The use of Liase with weedmaster® DUO, when used to control ANNUAL weeds, MAY improve the performance of weedmaster® DUO under adverse environmental conditions such as cool, cloudy weather, and assist in minimising the antagonism in tank mixes of weedmaster® DUO and Flowable triazine herbicides, as well as Grunt 750 WDG.
Liase may be corrosive to metal parts of the sprayer. Thoroughly flush tanks, pumps and nozzles with water after use.
Pulse® Penetrant – RATE: 500 mL/100L spray solution. Add when treating Bracken (boom application), Gorse, Eucalypt suckers, Coppice and Lantana.

Tank mixtures - Insecticides
This product is compatible with the following insecticides: Dimethoate, Fenitrothion 1000, Imidan*, Le-Mat*/Comrad®, Lorsban* 500, Metasystox*, Perfekthion* EC400, ULV, and emulsifiable concentrates of dimethoate and fenitrothion. Other insecticides have not been tested.

Application Information
This product is a non-selective translocated herbicide. Direct spray contact, or even slight drift, may cause severe injury or destruction of any growing crop or other desirable plants including trees. Clean all equipment after use by thoroughly washing with water.

Boom equipment
Use recommended rates of this product in 75-200 L of clean water per hectare. When using this product at 500 mL-1.5 L/ha (eg. in conservation tillage) spray volumes in the range 25-100 L/ha are preferred. Fan nozzle equipment is recommended, using pressures in the range 240-280 kPa. Boom height must be set to ensure double overlap of nozzle patterns at the top of the weed canopy.

High volume application (eg. knapsack and handgun equipment)
Adjust equipment to achieve an even spray pattern; for handgun equipment a D6 spray tip (Spraying Systems Australia P/L) or equivalent, and an operating pressure of 400-700 kPa are recommended. Apply to ensure complete and uniform wetting of all foliage.

Low volume application (gas gun or splatter gun)
Apply as an even spray to cover all foliage. Refer to Weeds Controlled for the dilution and volume of mixture to be applied. The dilution is specific as “Low volume mixture, Product:Water”. For example, a 1:9 mixture equals one part product plus 9 parts water.

Wiper equipment
Wiper equipment (eg. ropewick, canvas, felt or carpet applicators) may be used to apply this product on to weeds growing in oilseed crops, sugarcane, cotton, seed and pod vegetables and tree and vine crops specified in this label, and in pasture and non-crop areas. Avoid contact with desirable vegetation. Operate wiper equipment a minimum of 10 cm above the crop or pasture. Weeds should be at least 15 cm above the crop or pasture at time of application. Speed of travel should be no greater than 8 km/h. Best results are achieved at lower speeds and where two applications are made in opposite directions (double pass). Where weeds are of variable height, or occur in dense infestations or clumps, some plants may not be contacted by the herbicide solution. In these cases repeat treatment may be necessary. Mix only enough herbicide solution for immediate requirements. DO NOT store mixed solution for more than a few days. Flush out equipment with water after use.
RATE: Mix 1 L of this product with 2 L clean water to prepare 33% solution. This product may be used according to the above directions for suppression or control of many annual and perennial weeds. See Weeds Controlled tables for specific use recommendations.

DO NOT add oils to weedmaster® DUO/ water mixture, otherwise difficulty in application and reduced weed control may occur.
CAUTION: CDA equipment produces a fine spray pattern which is not easily visible. Ensure that the spray pattern or drift does not contact foliage or any other green tissue of desirable plants, since severe injury or destruction may result.

Aerial equipment
Aerial equipment may be used to apply this product only in pasture or fallow situations prior to establishment of field crops, fodder crops, or new pasture, and for pre-harvest application to sorghum crops. DO NOT use in intensive horticultural cropping areas. Use recommended rates specified in this label up to a maximum limit of 4 L/ha. When applying this product by helicopter in combination with Associate® for control of Blackberry in forestry and other specific situations, the higher rate of weedmaster® DUO may be applied. Please refer to the Associate® label for specific recommendations. For Micronair and boom equipment, apply in a minimum spray volume of at least 20 L/ha. Droplets with an average size (or VMD) of 250-350 micron diameter are recommended. Swath width should be 15-17 m.
Thoroughly wash aircraft especially landing gear after each day of spraying to remove herbicide residues.
Application on hilly terrain: As spraying height may vary, to maximise target contact, increase water volume to 30-80 L/ha and increase droplet size to at least 300 micron VMD.
Application under Summer conditions: High temperatures and/or low relative humidity cause excessive evaporation of spray droplets which may reduce results. When temperature reaches 25˚C, increase water volume by at least 30 L/ha, & increase droplet size to at least 300 micron VMD. DO NOT apply this product by aircraft when temperature is above 30˚C.
Avoid Drift: DO NOT use when breeze is blowing toward nearby desirable plants. DO NOT use with spraying equipment or under meteorological conditions which could be expected to cause spray to drift onto nearby susceptible plants, adjacent crops, crop lands or pastures. Equipment settings which produce fine droplets (150 microns or less), winds over 8 km/h, inversion conditions, still air and hot dry days all contribute to drift.

Application checklist
• DO NOT treat weeds under poor growing or dormant conditions (such as occur in drought, waterlogging, disease, insect damage or following frosts) as reduced weed control may result. Reduced efficacy may also occur when treating weeds heavily covered with dust or silt.
• DO NOT add additional surfactant, or mix with any other agricultural chemicals, herbicide oils, or any other materials except as specifically directed on this label.
• Rainfall occurring up to 6 hours after application may reduce effectiveness. Heavy rainfall within 2 hours after application may wash the chemical off the foliage & a repeat treatment may be required.
• DO NOT disturb treated weeds by cultivation, sowing or grazing for one day after treatment of annual weeds and 7 days for perennial weeds, to ensure herbicide absorption.
• A Withholding Period for grazing stock is not required. However, it is recommended that grazing of treated plants be delayed (as recommended above) to ensure herbicide absorption. Certain plants such as, Soursob, St John’s Wort & Bracken, may be naturally toxic to stock. Where known toxic plants are present, grazing should be delayed until complete browning of treated plants has occurred.
• The addition of non-ionic surfactant is recommended at a rate of 100 mL of a 600 g/L product (or equivalent) per 100 L spray solution.
• Delay treatment of plants wet with dew or rain if water droplets run-off when plants are disturbed.

Equipment maintenance & useage
Spray solutions of this product should be mixed, stored & applied only in stainless steel, aluminium, brass, copper, fibreglass or plastic or plastic-lined containers. This product or spray solutions of this product, react with galvanised steel or unlined steel (except stainless steel) containers and tanks, to produce hydrogen gas which may form a highly combustible gas mixture. This gas mixture can flash or explode if ignited by open flame spark, welder’s torch or other ignition source. Spray tank, pumps, lines & nozzles should be thoroughly rinsed with clean water following application to prevent extensive corrosion. Thoroughly wash aircraft, especially landing gear after each day of spraying to remove herbicide residues.

RESISTANT WEEDS WARNING
GROUP 9 HERBICIDE
Nufarm weedmaster® DUO Herbicide (“weedmaster® DUO”) is a member of the Glycines group of herbicides. weedmaster® DUO has the inhibitors of EPSP synthase mode of action. For weed resistance management weedmaster® DUO is a Group 9 herbicide. Some naturally-occurring weed biotypes resistant to weedmaster® DUO and other Group 9 herbicides may exist through normal genetic variability in any weed population. The resistant individuals can eventually dominate the weed population if these herbicides are used repeatedly. These resistant weeds will not be controlled by weedmaster® DUO or other Group 9 herbicides. Since the occurrence of resistant weeds is difficult to detect prior to use, Nufarm Australia Limited accepts no liability for any losses that may result from the failure of weedmaster® DUO to control resistant weeds.
