Tips For Use

Restraints: 

• Do not apply this product to salt or erosion-prone areas.
• Do not apply this product within 100 metres of a recognised watercourse.
• Do not apply Graslan on land with a slope greater than 20 percent (11 degrees).
• Do not apply Graslan under conditions that will cause pellet movement to non-target areas during application.
• Retain at least 20 percent of the original tree population in wildlife corridors that are at least 100 metres wide. These are essential for shade and protection of livestock and native fauna. Ideally, shelter belts should traverse variable terrain, particularly ridgelines and hilltops as well as water courses, and link other vegetated corridors where possible.
• For long-term viability retain a minimum of S hectares for shade areas, regardless of vegetation type.
• Do not apply Graslan on field crops, near desirable trees or shrubs or to areas into which their roots may extend or in locations where the chemical may be washed into contact with their roots as injury or death may occur.
• Do not apply Graslan to land to be put under field crops within 5 years of application.

Other Limitations: For Native Vegetation

• Use of Graslan on native vegetation must be done in accordance with State and/or Local legislation, including the Vegetation Management Act 2000 in Queensland.

General Instructions: 

• Graslan may be applied at any time of the year. 
• Treatments become effective after sufficient rainfall has occurred to move the chemical into the root zone where it is absorbed by woody plants. 
• Applications just prior to seasonal rainfall give the most rapid response. 
• Herbicidal activity will continue for several seasons after application. 
• During this time woody plants may go through repeated defoliations and regrowths until death occurs. 
• A single application is normally effective for several years. 
• Forage grass production usually increases as woody weed competition is reduced. 
• Increased grass production is also dependant on adequate rainfall and an acceptable grazing management programme. 
• It is important to allow grasses to seed and seedlings to become established after treatment before grazing pressure is increased. 
• Areas treated with Graslan may be overseeded with suitable pasture species. 
• Consult your agricultural specialist for details on suitable seeding rates, timing and fertiliser application programme. The residual action of Graslan may be impaired if fire occurs before clay pellets are dissolved and the chemical has moved into the root zone.

Hand Application:

• It is recommended that gloves be used during hand application. 
• Apply Graslan by uniformly distributing the desired area by hand after weighing out the recommended quantity of pellets. 
• The best way to calibrate yourself is to weigh a normal handful of pellets. 
• If, for example, a handful weighs 20 grams, then this will treat 20 to 40 m2 at the rate of 0.5 to 1 g/m2.
• Dispenser Pack: Apply Graslan by uniformly distributing by hand after dispensing a single dose (7 g) from the dispenser unit. 
• Apply the pellets at 1 to 2 g per m2. One dose (7 g) will treat 7 to 3.5 m2 at these rates.

Additional Instructions:

• When applying pellets, distribute them under the tree or regrowth canopy from the root crown or stems to 30 cm beyond the drip zone of the plants you want to control. 
• The time required for complete plant death depends on soil type, amount of rainfall, root depth, plant species, plant density and rate of Graslan used. 
• Some species may go through several defoliations from 6 months to 2 years before dying. 
• Timber and regrowth control with Graslan pellets may be variable when used on soils with high clay content and high organic matter or when treating deep-rooted or more tolerant species.

Treating Individual Trees By Hand:

• Estimate the area within 30 cm beyond the drip zone, i.e. the area under the plant canopy. 
• It is essential that this area is treated as evenly as possible, with pellets being spread from the tree trunk to slightly beyond the drip line formed by the branches. 
• Do not throw all the pellets at the base of the tree trunk. 
• This will waste material and could result in poor control.

Treatment Of Clumps Of Trees Or Patches Of Regrowth By Hand:

• Graslan pellets are particularly effective in treating areas of regrowth. 
• Estimate the area within 30 cm beyond the drip zone and apply the Graslan pellets on a grid pattern to uniformly cover the area. 
• Pellets should be applied over the top of regrowth if at all possible in an attempt to maintain a good distribution pattern.

Treating Fence Lines By Hand:

• Estimate the area to be treated, along the fence line and then apply Graslan pellets on both sides of the fence line as evenly as possible within the area extending 30 cm out beyond drip zone.

Aerial And Ground Application:

• Apply Graslan by uniformly distributing with an approved aircraft or ground driven air equipment, after calibration to achieve the desired application rate.

1. Aerial Application

• • Aerial application of Graslan can be carried out by fixed wing aircraft or helicopter fitted with specially designed application apparatus. 
  • Use a Positive Metering Device (Meterate) for fixed wing aircraft and Isolair or similar precision equipment for helicopters. 
  • A minimum flying height of 20 metres above the canopy of the target plants must be maintained. 
  • The swath width is dependent on the type of spreader used. 
  • The target areas must be correctly marked out and flown with the aid of GPS (Global Positioning System) or markers clearly visible to the operator or a method of marking approved by FMC Australasia Pty Ltd.

2. Ground Application

• • Ground applications of Graslan can be carried out in suitable areas by accredited operators.

Management Strategies for Prickly Acacia & Parkinsonia:

• The application method (distribution) of Graslan Herbicide is different for prickly acacia compared to parkinsonia due to the growth habit of the plant; however, the best time of application for both is prior to the wet season.
• For prickly acacia, Graslan pellets need to be placed right at the base of the plant for optimum control. This is because the plant acts like a funnel during rainfall events as the rain drains down the branches to the base of the plant. Therefore, in low rainfall areas, this method gives the quickest level of control as the chemical is activated quickly and reaches the large taproot system more easily.
• For parkinsonia, Graslan pellets need to be scattered evenly within 30 cm beyond the drip zone of the plant as the many surface roots are able to absorb the herbicide more evenly instead of placing all the pellets at the base of the plant. This also helps in residual control of seedlings that germinate in subsequent seasons.

Cleaning Application Equipment:

• Thoroughly clean all traces of Graslan from vessels holding pellets, e.g. bucket and gloves, after use.
• Residues cleaned from this application equipment should not be emptied on areas where they will contact roots of desirable trees, shrubs or plants.

Protection Of Crops, Native And Other Non-Target Plants:

• Do not allow any roots of desirable plants, trees or ornamentals to contact Graslan. 
• Graslan may cause temporary herbicidal symptoms to appear on perennial grasses, including buffel grass, particularly after extended dry periods. 
• Higher rates of application of Graslan(2 g/m2) may kill grasses, particularly native annuals. 
• This effect can be minimised by application when grasses are dormant (autumn application). 
• Graslan may seriously injure desirable forage plants such as pasture legumes and other broadleaf plants. 
• These species may regenerate in subsequent seasons.

Protection Of Livestock:

• Poisonous plants may become more palatable after application of granules and stock should be kept away from these plants until they have died down.

Storage:

• Store in the closed original container in a dry, cool well-ventilated area out of direct sunlight. 
• Do not store near food, feedstuffs, fertilisers or seed.
