Rapid 750 WG Herbicide (Tribenuron-Methyl)

Tips For Use

General Instructions:

Best results are obtained when Rapid 750 WG 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 the rate used, sensitivity and size of target weeds and environmental conditions at the time of and following application.

Rapid 750 WG 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 Rapid 750 WG 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. Rapid WG is compatible with Glyphosate Herbicides.

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 Rapid 750 WG 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.

Do not apply to weeds that are not actively growing or stressed by any cause such as adverse weather conditions, drought and water logging.  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.

Crop Options:

Land previously treated with Rapd 750 WG Herbicide may be sown to any of the specified crops after the interval indicated in the following table:

 # NOTE: Rapid 750 WG 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 15οC 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 rapid 750 wg herbicide alone as a preceding fallow or pre-crop treatment.

Restraints:

Do not apply to weeds that are not actively growing or stressed by any cause such as adverse weather conditions, drought and water logging. 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 – 50L/ha
• Aerial application – 20L/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.

Spray Preparation:

• Rapid 750 WG Herbicide is a dry flowable formulation to be mixed with water and applied as a spray.
• Partially fill the spray tank with water. Measure the amount of Imtrade Rapid 750 WG Herbicide required for the area to be sprayed. Add the correct amount of Imtrade Rapid 750 WG 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, Rapid 750 WG Herbicide must be in suspension before adding the companion herbicide or surfactant/wetting agent.

Storage:

• 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.

Safety Directions:

• Will irritate the eyes. 
• Avoid contact with eyes.
• When preparing spray wear elbow-length PVC gloves and face shield or goggles. 
• If product in eyes, wash out immediately with water. 
• After use and before eating, drinking, or smoking, wash hands, arms and face thoroughly with soap and water. 
• After each day’s use, wash gloves and face shield or goggles.

First Aid:

• If poisoning occurs, contact a doctor or Poisons Information Centre (Phone Australia 13 11 26).
• Additional information is listed in the Safety Data Sheet (SDS).
