General Instructions

 

- SCRUBMASTER 200 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 SCRUBMASTER 200 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 SCRUBMASTER 200 may be impaired if fire occurs before clay pellets are dissolved and the chemical has moved into the root zone.

 

Application

 

HAND APPLICATION

It is recommended that gloves be used during hand application. Apply SCRUBMASTER 200 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 SCRUBMASTER 200 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 metre square. One dose (7 g) will treat 7 to 3.5 square metres 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 SCRUBMASTER 200 used. Some species may go through several defoliations from 6 months to 2 years before dying. Timber and regrowth control with SCRUBMASTER 200 pellets may be variable when used on soils with high clay content 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

SCRUBMASTER 200 pellets are particularly effective in treating areas of regrowth. Estimate the area within 30 cm beyond the drip zone and apply the SCRUBMASTER 200 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 SCRUBMASTER 200 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 SCRUBMASTER 200 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 SCRUBMASTER 200 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 Cheminova.

 

2. Ground Application

Ground applications of SCRUBMASTER 200 can be carried out in suitable areas by accredited operators.

 

Cleaning Spray Equipment

Thoroughly clean all traces of SCRUBMASTER 200 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.

 

Restraints

 

DO NOT apply this product to salt or erosion prone areas.

 

DO NOT apply this product within 100 metres of a recognised water course.

 

DO NOT apply SCRUBMASTER 200 on land with a slope greater than 20 percent (11 degrees).

 

DO NOT apply SCRUBMASTER 200 under conditions which 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 hill tops as well as water courses, and link other vegetated corridors where possible.

 

FOR LONG TERM VIABILITY retain a minimum of 5 hectares for shade areas, regardless of vegetation type.

 

DO NOT apply SCRUBMASTER 200 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 SCRUBMASTER 200 to land to be put under field crops within 5 years of application.

 

Resistance Warning

 

Cheminova SCRUBMASTER 200 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, Cheminova 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 Cheminova representative.

 

Protection of wildlife, fish, crustaceans and environment

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

 

Protection of crop, native and other non-target plants

DO NOT allow any roots of desirable plants, trees or ornamentals to contact SCRUBMASTER 200. SCRUBMASTER 200 may cause temporary herbicidal symptoms to appear on perennial grasses, including buffel grass, particularly after extended dry periods. Higher rates of application of SCRUBMASTER 200 (2 g/m2) may kill grasses, particularly native annuals. This effect can be minimised by application when grasses are dormant (autumn application). SCRUBMASTER 200 may seriously injure desirable forage plants such as pasture legumes and other broadleaf plants. These species may regenerate in subsequent seasons.

 

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.

 

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.

 

Disposal

Do not dispose of granules on-site. Shake bag contents into application equipment until the bag is empty. Do not dispose of undiluted chemicals on-site. Puncture or shred and bury empty bags in a local authority landfill. If no landfill is available, bury the containers below 500 mm in a disposal pit specifically marked out and set up for this purpose clear of waterways, desirable vegetation and tree roots. Empty bags and product should not be burnt.
