For the control of certain broadleaf weeds in fallow and pre-crop situations as per Directions for Use Table.

GENERAL INSTRUCTIONS
Best results are obtained when Express herbicide is applied to young actively growing weeds. The rate will depend on weed spectrum at time of application. The degree of control and duration of effect are dependent on rate used, sensitivity and size of target weeds and environmental conditions at the time of and following application.
DuPont Express herbicide stops growth of susceptible weeds rapidly. However, typical symptoms of dying weeds (discolouration) may not be noticeable for 1 to 3 weeks after application depending on the environmental conditions and susceptibility. Warm, moist conditions following treatment promote the activity of Express herbicide, while cold, dry conditions delay activity. Weeds hardened-off by cold weather and/or drought stress will be less susceptible.
Where recommended the addition of Glyphosate will enhance knockdown and control of weeds. It also helps minimise the risk of resistant weeds occurring.

RESISTANT WEEDS WARNING
GROUP B HERBICIDE
DuPont Express herbicide is a member of the Sulfonylurea group of herbicides. The product has the Inhibitors of Acetolactate Synthase (ALS inhibitors) mode of action. For weed resistance management, Express® herbicide is a Group B herbicide.
Some naturally-occurring weed biotypes resistant to the product and other Group B 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 the product or other Group B herbicides.
Since the occurrence of resistant weeds is difficult to detect prior to use, DuPont accepts no liability for any losses that may result from failure of this product to control resistant weeds.
Large numbers of healthy surviving weeds can be an indication that resistance is developing. Efforts should be taken to prevent seed set of these survivors.
DO NOT use an ALS inhibitor herbicide against the same weed in the crop following the use of Express® herbicide alone either as a fallow or pre-crop treatment. This does NOT apply if the fallow or pre-crop use of Express® herbicide was tank mixed with glyphosate.
Avoid the prolonged use of ALS inhibitor herbicides on the same weed population.
If the user suspects that an ALS inhibitor resistant weed is present, Express® herbicide or other ALS inhibitors herbicides recommended for the control of that weed should not be used.
Strategies to minimise the risk of herbicide resistance are available. Consult your farm chemical supplier, consultant, local Department of Agriculture or Primary Industries, or local DuPont Representative.
Crop Safety
DO NOT apply Glean cereal herbicide, Ally herbicide or Logran in a tank mix with Express herbicide as a fallow or pre-crop treatment.
Spray Preparation
DuPont Express herbicide is a dry flowable formulation to be mixed with water and applied as a spray. Partially fill the spray tank with water. Using the Express® herbicide measuring cone provided, measure the amount of Express herbicide required for the area to be sprayed. Add the correct amount of Express® herbicide to the spray tank with the agitation system engaged. Top up to the correct volume with water. THE MATERIAL MUST BE KEPT IN SUSPENSION AT ALL TIMES BY CONTINUOUS AGITATION.
In tank mixes, Express herbicide must be in suspension before adding the companion herbicide or surfactant/wetting agent.
Compatibility
DuPont Express herbicide is compatible with glyphosate herbicides e.g. Nufarm Glyphosate CT and Roundup CT.
Use of Surfactant/Wetting Agent
Always add non-ionic surfactant (1000 g/L - non buffering type) at 100 mL/100 L (0.1 v/v) of final spray volume. When applying Express® herbicide alone by air in addition to a non-ionic surfactant add a mineral spray oil at 1 L/100 L (1 v/v) of final spray volume.
Ground Spraying
Use a boom spray properly calibrated to a constant speed and rate of delivery to ensure thorough coverage and a uniform spray pattern. Avoid overlapping and shut off spray booms while starting, turning, slowing or stopping. Apply a minimum of 50 L prepared spray/ha.
Aerial Spraying
Apply in a minimum of 20 L/ha water. Application in 30 L/ha will improve performance reliability. Avoid spraying in still conditions and in winds likely to cause drift onto adjacent sensitive crops or fallow areas likely to be planted to these crops - see Crop Options section. Turn off spray boom whilst passing over creeks and dams.
DO NOT apply when a temperature air inversion is likely to occur.
Sprayer Cleanup
To avoid subsequent injury to crops immediately after spraying thoroughly remove all traces of Express herbicide from mixing and spray equipment as follows:
- Immediately after spraying, drain tank completely. Any contamination on the outside of the spraying equipment should be removed by washing with clean water.
- Rinse inside of tank with clean water and flush through boom and hoses using at least one-tenth of the spray tank volume. Drain tank completely.
- Half fill tank with clean water adding household ammonia to give a 1 solution (equivalent ratios include 1/3 L household ammonia product (containing 9.5 ammonia) for each 100 L of tank volume. Agitate, and then flush the boom and hoses with the cleansing solution. Top up with water making sure the tank is completely full and allow to stand for 15 minutes with agitation engaged. Again flush the boom and hoses and drain tank completely.
- Nozzles and screens should be removed and cleaned separately with ammonia solution at the same concentration as used for the sprayer.
- Rinse the tank with clean water and flush through boom and hoses using at least one-tenth of the spray tank volume. Drain tank completely.
- DO NOT spray the tank rinsate onto sensitive crop or land intended for cropping with sensitive crop.
NOTE: If not possible to drain the tank completely, step 3 must be repeated before going on to step 4.
Crop Options
Land previously treated with Express® herbicide may be sown to any of the specified crops after the interval indicated in the following table:

Minimum interval: 3 days
Crops**: Barley, Oats, Wheat
Minimum interval: # 7 or 21 days
Crops**: Maize, Mung beans, Sorghum, Soybeans, Sunflowers

# NOTE: DuPont Express is broken down in soil, primarily by chemical hydrolysis, but to a lesser degree by microbial degradation. Breakdown is fastest in warm, wet acid soils and slower in cold, dry alkaline soils. For the above summer crops, if minimum soil temperatures at planting depth are less than or equal to 15 C for three consecutive days, then plantback intervals should be extended to 21 days.
** As a herbicide resistance countering measure, DO NOT use an ALS inhibitor herbicide in any of these crops following the use of Express herbicide alone as a preceding fallow or pre-crop treatment.

DIRECTIONS FOR USE
RESTRAINTS
DO NOT apply to weeds that are not actively growing or stressed by any cause such as adverse weather conditions, drought, waterlogging. Broadleaf weeds under stress frequently become less susceptible to herbicide activity. This may result in an incomplete kill or only growth suppression. If heavy grazing has occurred allow regrowth before spraying.
Minimum volumes of prepared spray to be applied:
- ground application - 50 L/ha
- aerial application - 20 L/ha.
Use prepared spray suspensions within two days of preparation, otherwise significant breakdown may occur.
DO NOT apply if rainfall is expected within 2 hours.

Express® alone- NSW and Qld ONLY
