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. Express herbicide stops growth of susceptible weeds rapidly. However, typical symptoms of dying weeds (discolouration) may not be noticeable for 1 to 3 weeks afterapplication 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.

 

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.

 

The Role of Express in Weed Resistance Management

 

Although Express alone is registered to control certain weed species, as Express is a Group B fallow herbicide, it is recommended that Express should always be tank mixed with Glyphosate. Some broadleaf weeds, such as Milk thistle, are developing tolerance to Glyphosate and/or ALS inhibitor herbicides.

The addition of Express to Glyphosate, can help to overcome some performance issues and extend the effectiveness of both products in the face of herbicide resistance.

 

How to get the best out of Express
1. Target the right weeds
2. Weed size is critical
3. Avoid spraying stressed weeds
4. Consider what cropping options you want to keep open

 

Express is effective in fallow weed control.

 

Resistant Weeds Warning

 

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 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 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 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 FMC 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

 

Express 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 required for the area to be sprayed. Add the correct amount of Express 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 must be in suspension before adding the companion herbicide or surfactant/wetting agent.

 

Compatibility

 

Express herbicide is compatible with glyphosate herbicides e.g. Nufarm Glyphosate CT and RoundupCT.

 

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 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 from mixing and spray equipment as follows:

  1. Immediately after spraying, drain tank completely. Any contamination on the outside of the spraying equipment should be removed by washing with clean water.

  2. 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.

  3. 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.

  4. Nozzles and screens should be removed and cleaned separately with ammonia solution at the same concentration as used for the sprayer.

  5. 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.

  6. 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.

 

Protection of Crops, Native and other Non-Target Plants

 

Injury to or loss of desirable trees, vegetation including aquatic plants may result from failure to observe the following: Tolerance of other crops (grown through to maturity) should be determined on a small scale before resowing into larger areas.

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.

 

Protection of Wildlife, Fish, Crustaceans and Environment

 

DO NOT contaminate streams, rivers, waterways with the chemical or used containers.

 

Protection of Livestock

 

The use pattern is such that a withholding period for harvest or grazing is not required. It is recommended however, not to graze treated areas for 2 to 3 days to ensure adequate control is achieved.

 

Storage and Disposal

 

Store in the closed, original container in a dry, cool, well-ventilated area, out of direct sunlight. Keep from contact with fertilisers, insecticides, fungicides and seeds. DO NOT re-use container. Triple 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 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.

 

Safety Directions
