Ozcrop Tebuthiuron 200 Herbicide

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 OzCrop Tebuthiuron 200 Herbicide on land with a slope greater than 20% (11 degrees).
• Do not apply OzCrop Tebuthiuron 200 Herbicide under conditions that will cause pellet movement to non-target areas during application.
• Retain at least 20% of the original tree population in wildlife corridors at least 100 metres wide. These are essential for shade and protection of livestock and native fauna.
• Ideally, shelterbelts should traverse variable terrain, particularly ridgelines and hilltops as well as watercourses and link other vegetated corridors where possible.
• For long-term viability, retain a minimum of 5 hectares for shade areas, regardless of vegetation types.
• Do not apply OzCrop Tebuthiuron 200 Herbicide on field crops, near desirable trees or shrubs or into 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 OzCrop Tebuthiuron 200 Herbicide to land to be put under field crops within 5 years of application.

Limitations: For Native Vegetation

• Use of OzCropTebuthiuron 200 Herbicide on native vegetation must be done in accordance with state and/or local legislation, including the Vegetation Management Act 2000 in Queensland.

Application Methods:

Hand Application:

• Gloves must be used during hand application.
• Apply OzCrop Tebuthiuron 200 Herbicide by uniformly distributing by hand using a hand dispenser over the desired area after weighing out the recommended quantity of pellets using a volumetric measuring cup.
• As an example, a measured weight or measured volume of 20 grams will treat 10-20 m2 at the rate of 1-2 g/m².
•  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 OzCrop Tebuthiuron 200 Herbicide used.
• Some species may go through several defoliations from 6 months to 2 years before dying.
• Timber and regrowth control with OzCrop Tebuthiuron 200 Herbicide 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.
• This area must be 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:

• OzCrop Tebuthiuron 200 Herbicide pellets are particularly effective in treating areas of regrowth. Estimate the area within 30 cm beyond the drip zone and apply the OzCrop Tebuthiuron 200 Herbicide 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 OzCrop Tebuthiuron 200 herbicide pellets on both sides of the fence as evenly as possible within the area extending 30 cm out beyond the drip zone.

Aerial And Ground Application:

• Apply OzCrop Tebuthiuron 200 Herbicide by uniformly distributing with an approved aircraft or ground-driven air equipment after calibration to achieve the desired application rate.
• OzCrop Tebuthiuron 200 Herbicide 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 re-growths 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 dependent on adequate rainfall and an acceptable grazing management program.
• It is important to allow grasses to seed and seedlings to become established after treatment before grazing pressure is increased.
• Areas treated with OzCrop Tebuthiuron 200 Herbicide may be over-seeded with suitable pasture species.
• Consult your agricultural specialist for details on suitable seeding rates, timing and fertiliser application programs.
• The residual action of OzCrop Tebuthiuron 200 Herbicide may be impaired if a fire occurs before clay pellets are dissolved, and the chemical has moved into the root zone.

Aerial Application:

• Aerial application of OzCrop Tebuthiuron 200 Herbicide can be carried out by accredited fixed-wing aircraft or helicopters 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 between 10 to 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 a GPS (Global Positioning System) or markers clearly visible to the operator or a method of marking approved by OzCrop Pty Ltd.

Ground Application:

• Ground applications of OzCrop Tebuthiuron 200 Herbicide can be carried out in suitable areas by accredited operators.
• Ground applications of OzCrop Tebuthiuron 200 Herbicide can be carried out in suitable areas by precision low application rate spreaders.

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

• Do not allow any roots of desirable plants, trees or ornamentals to contact OzCrop Tebuthiuron 200 Herbicide.
• OzCrop Tebuthiuron 200 Herbicide may cause temporary herbicidal symptoms to appear on perennial grasses, including buffel grass, particularly after extended dry periods.
• Higher rates of application of OzCrop Tebuthiuron 200 Herbicide (2g/m2) may kill grasses, particularly native annuals.
• This effect can be minimised by the application when grasses are dormant (autumn application).
• OzCrop Tebuthiuron 200 Herbicide 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 the application of granules, and stock should be kept away from these plants until they have died down.

Protection Of Wildlife, Fish, Crustaceans And the Environment:

• Do not contaminate streams, rivers or waterways with the granules or used containers.

Cleaning Application Equipment:

• Thoroughly clean all traces of OzCrop Tebuthiuron 200 Herbicide from application equipment holding pellets e.g. bucket, measuring cylinder and gloves, after use.
• Residues cleaned from the application equipment should NOT be emptied onto areas where they will contact the roots of desirable trees, shrubs or plants.

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.
• Do not dispose of granules on site.

Safety Directions:

• Harmful if swallowed.
• It 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, a washable hat and elbow-length chemical-resistant gloves.
• Wash hands after use.
• After each day’s use, wash gloves and contaminated clothing.
