General Instructions

Graslan® Aerial3D® HiLoad 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® Aerial3D® HiLoad 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® Aerial3D® HiLoad 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® Aerial3D® HiLoad by uniformly distributing by hand over the desired area 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® Aerial3D® HiLoad by uniformly distributing by hand after dispensing a single dose (5 g) from the dispenser unit. Apply the pellets at 1 to 2 g per m2. One dose (5 g) will treat 7 to 3.5 m2 at these rates.


Additional Application 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® Aerial3D® HiLoad used. Some species may go through several defoliations from 6 months to 2 years before dying. Timber and regrowth control with Graslan® Aerial3D® HiLoad pellets may be variable when used on soils with high clay content high organic matter or when treating deep rooted or more tolerant species.


Aerial and Ground Application

Apply Graslan® Aerial3D® HiLoad 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® Aerial3D® HiLoad 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® Aerial3D® HiLoad can be carried out in suitable areas by accredited operators.


Herbicide Resistance Warning 

Graslan® Aerial3D® HiLoad Herbicide is a member of the Ureas group of herbicides. The product has inhibitors of photo-synthesis at photosystem II mode of action. For weed resistance management, the product is a Group C herbicide.

Some naturally-occurring weed biotypes resistant to the product and other Group C 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 this product or other Group C herbicides. Since the occurrence of resistant weeds is difficult to detect prior to use, FMC Australasia Pty Ltd accepts no liability for any losses that may  result from the failure of this product to control resistant weeds. Strategies to minimise the risk of herbicide resistance are available. Contact your farm chemical supplier, consultant, local Department of Agriculture or local FMC representative.


Storage and Disposal

 Single-rinse or shake remainder into spray tank/water/dip/drench, etc. DO NOT dispose of undiluted chemicals on site. Puncture and deliver empty packaging to an approved waste management facility. If an approved waste management facility is not available, bury the empty packaging 500 mm below the surface in a disposal pit specifically marked and set up for this purpose, clear of waterways, desirable vegetation and tree roots, in compliance with relevant local, state or territory government regulations. DO NOT burn empty containers or product.


Safety Directions

Harmful if swallowed. Will irritate the eyes. Repeated exposure may cause allergic disorders. Avoid contact with eyes and skin. When opening the container and preparing the product and using the prepared product wear cotton overalls buttoned to the neck and wrist and a washable hat and elbow-length gloves. Wash hands after use. After each day’s use wash gloves and contaminated clothing.


First Aid

If poisoning occurs, contact a doctor or Poisons Information Centre. Phone Australia 13 11 26.
