DIRECTIONS FOR USE

RESTRAINTS:

DO NOT apply to weeds which may be stressed (not actively growing) due to prolonged periods of extreme cold, moisture

stress (water-logged or drought affected), poor nutrition, presence of disease, damage or previous herbicide treatment, as

reduced levels of control may result.

DO NOT spray if rain is likely within one hour or if foliage is wet from rain or dew.

DO NOT burn off, cut or clear blackberry or other woody weeds for at least six months after spraying.

DO NOT apply by aerial application in wind in excess of 15 km/hr and air temperatures above 35°C.

In areas prone to flooding treatment should commence after any annual flooding as such areas flooded within 9 months

following application may have reduced results.

GENERAL INSTRUCTIONS

MINIMUM RECROPPING PERIODS - Black Cracking

Clay Soils, NNSW & Qld.

A: Boom Application

These plantback periods are based on a normal rainfall

pattern. During drought conditions (or when the rainfall is

less than 100 mm for a period of 4 months or greater) the

plantback period may be significantly longer.

Table B: Blanket Wiper Application

NOTE:

Before using Grazon DS in tank mixes with other herbicides,

check the plant-back information on all product labels.

The most residual product, i.e. the product with the longest

plant-back period, will determine the time between spraying

and planting.

COMPATIBILITY

Follow any regional restrictions, and all directions and

restrictions on the label, of any chemical mixed with

Grazon DS (e.g. 2,4-D amine). Grazon DS is compatible

with the following herbicides: Dow AgroSciences

2, 4-D Amine 625, Abound

300, 2,4-D amine, DP

600,

glyphosate, metsulfuron-methyl, Roundup

CT, Starane

Grazon DS is compatible with the following adjuvants, as

per DIRECTIONS FOR USE: Uptake

Spraying Oil, BS1000

Pulse

Penetrant.

MIXING

Mix only with water.

Half fill the spray unit with water, and add the required

amount of Grazon DS. Add the remaining water with the

agitator running. If required, then add spray oils or wetters

(surfactants). Maintain mechanical or by-pass agitation

in the spray tank during spraying. Only mix sufficient

solution for immediate daily use and avoid storing.

APPLICATION

1.

WOODY WEED SITUATIONS

Weeds need to be actively growing for herbicides

to have optimum effect. Delay treatment until all

regrowth has had time to grow to approximately

1 metre in situations which have been bulldozed,

slashed, burnt, ploughed or areas having a previous

chemical treatment.

A.

High Volume Spraying

Thorough coverage of foliage to the point of run-off is

essential, however, avoid excess spraying which is

wasteful of chemical.

Hand Gun

Apply the recommended mix to give full coverage of

leaves and stems through a No. 6 to 8 tip at 700 to

1500 kPa (400 to 500 kPa for St John’s wort).

A spray volume of 3000 to 4000 L per infested hectare

of 1 to 2 metre high blackberry (30 to 40 L/100 m

should be used.

Use 2000 L of spray mixture/ha of galenia infestation

(i.e. 20 L /100 m

infested area).

Knapsack

Apply the recommended spray mix to give full coverage

of leaves and stems. The final volume of application

should be similar to hand gun.

A spray volume of 3 to 4 L / 10 m

infested area should

be used.

A spray volume of 2 L / 10 m

should be used for an

area infested with galenia.

B.

Aerial Application

Apply in 200 L of water/ha using an aircraft to apply

100 L per pass on a double overlap pattern using

nozzle configurations to produce droplets of 250 to 350

micron diameter.

The potential for damage from drift can be greatly

reduced by avoiding unsuitable spraying conditions and

using spray pressure and nozzles to minimise the

production of small droplets.

DO NOT spray when wind exceeds 15 km/hr and/or air

temperature reaches 35°C.

C.

Controlled Droplet Application (C.D.A.)

Results similar to high volume spraying can be

obtained using Micron Herbi

or similar equipment.

Specimen Label

GRAZON DS

Select a nozzle to give a flow rate of 2 mL/sec and

sweeping action of approximately 1 m/sec to ensure a

droplet density of 20/cm. Use a marking agent, as

recommended by the equipment manufacturers, to

check spray coverage. Also, consult directions provided

with C.D.A. unit.

D.

Low Volume High Concentrate Application Techniques

Good control will be achieved, similar to high volume

application, where bush size enables good coverage of

entire bush. Use a marking agent, as recommended by

the equipment manufacturers, to check spray coverage.

Gas powered gun: Apply 50 mL shots to obtain

uniform coverage of 4 to 5 m

of surface area of bush.

This relates to 20 droplets/cm

of leaf surface.

Sprinkler sprayer: This technique involves using a

micro sprinkler that is connected to a hollow fibre glass

rod attached to a pneumatic knapsack sprayer. Use at

low pressures (50 to 200 kPa) and apply with a slow

sweeping action over the top of the plants ensuring

even coverage on the leaves.

E.

Boom Application

Application in a minimum spray volume of 200 L/ha for

galenia and St. John’s wort and 600 L of water/ha for

sicklepod. Flat fan nozzles are recommended, using

pressure in the range of 200-300 kPa. Boom height

must be set to ensure double overlap of nozzle patterns.

2.

FALLOW SITUATIONS

A.

Boom Application

Application of Grazon DS in a minimum spray volume

of 50 L/ha is recommended. Flat fan nozzles are

recommended, using pressure in the range of

200-300 kPa. Boom height must be set to ensure

double overlap of nozzle patterns.

B.

Blanket Wiper Application

Blanket needs to be made from durable and wettable

material with a rigid backing.

Blanket should be rigidly mounted behind motorised

vehicle (eg. tractor, 4-wheel drive vehicle) and set low

but never touching the ground. The chemical solution

should be fed to the blanket at a flow rate sufficient to

keep the blanket wet but not dripping. In thick patches

the blanket may require more frequent solution

recharge (rewetting).

Ideally, a scraper bar should be mounted in front of the

blanket in order to scrape or damage the bark (but not

sever the stems) prior to the blanket wiping the stems.

This scraper may be mounted at the front of the vehicle.

Two passes (in opposite direction) with the blanket

increases the contact with the plant. Ground speeds of

10 -15 kph are ideal for blanket wiping application.

CLEANING SPRAY EQUIPMENT

Rinsing

After using Grazon DS, empty the spray unit completely

and drain the whole system. Thoroughly wash inside

the unit using a pressure hose. Drain the spray unit,

and clean any filters in the tank, pump, lines, hoses

and nozzles.

After cleaning the spray unit as above, quarter fill with

clean water and circulate through the pump, lines,

hoses and nozzles. Drain and repeat the rinsing

procedure twice.

Decontamination

Before spraying cotton and other sensitive crops with

equipment that has been used to apply Grazon DS

(see PROTECTION OF CROPS, NATIVE AND OTHER

NON-TARGET PLANTS section).

Wash the tank and rinse the system as above. Then quarter

fill the tank and add a standard alkali based laundry

detergent at 500 g (or mL)/100 L water and circulate

throughout the system for at least 15 minutes. If using a

concentrated laundry detergent use 250 g (or mL)/100 L

water. Do not use chlorine based cleaners.

Drain the whole system. Remove filters and nozzles and

clean them separately. Finally flush the system with clean

water and allow to drain.

Rinse water should be discharged onto a designated

disposal area or, if this is unavailable, onto unused land

away from desirable plants and watercourses.

RESISTANT WEEDS WARNING

Grazon DS Herbicide is a member of the pyridines group of

herbicides. The product has the disrupters of plant cell

growth mode of action. For weed resistance management,

the product is a Group I herbicide.

Some naturally-occurring weed biotypes resistant to the

product and other disrupters of plant cell growth 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 the product

or other disrupters of plant cell growth herbicides.

Since the occurrence of resistant weeds is difficult to detect

prior to use, Dow AgroSciences accepts no liability for any

losses that may result from the failure of the 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 Dow AgroSciences

representative.

PROTECTION OF CROPS, NATIVE AND OTHER

NON-TARGET PLANTS

Crops susceptible to Grazon DS include, but are not limited

to: peas, lupins, lucerne, navy beans, peanuts, soybeans

and other legumes, cotton, flowers, fruit, hops,

ornamentals, shade trees and Pinus spp., potatoes,

safflower, sugar beet, sunflowers, tobacco, tomatoes,

vegetables and vines.

Grazon DS is damaging to susceptible crops during both

growing and dormant periods. Grasses are normally

unaffected and establish quickly after treatment.

Specimen Label

GRAZON DS

Picloram, one of the active constituents in this product can

remain active in the soil for extended periods depending on

soil type and application rate, rainfall, temperature,

humidity, soil moisture and soil organic matter.

DO NOT apply under weather conditions, or from spraying

equipment, that may cause spray to drift onto nearby

susceptible plants/crops, cropping lands, pastures,

waterways or native vegetation.

DO NOT allow physical spray drift onto waterways,

native vegetation and susceptible crops.

DO NOT apply close to, or in areas, containing roots of

desirable vegetation, where treated soil may be washed

onto areas growing (or areas to be planted with)

desirable plants.

DO NOT apply on sites where surface water from heavy rain

can be expected to run-off to areas containing, or to be

planted with susceptible crops or plants.

DO NOT move soil, which may have been treated to areas

where desirable plants are to be grown.

PROTECTION OF LIVESTOCK

Poisonous plants may become more palatable after

spraying and stock should be kept away from these plants

until they have died down.

Many plants remain poisonous after death, and stock

should not be allowed to access it, as there is a likelihood

that they may graze the dead material. Such material should

be burnt if possible.

PROTECTION OF WILDLIFE, FISH, CRUSTACEANS

AND ENVIRONMENT

DO NOT contaminate streams, rivers or waterways with the

chemical or used containers.

STORAGE AND DISPOSAL

Store in the closed, original container in a cool, well

ventilated area.

DO NOT store for prolonged periods in direct sunlight.

DO NOT store near food, feedstuffs, fertilisers or seed.

The method of disposal of the container depends on the

container type. Read the STORAGE AND DISPOSAL

instructions on the label that is attached to the container.

SMALL SPILL MANAGEMENT

Wear protective equipment (see SAFETY DIRECTIONS).

Apply absorbent material such as earth, sand, clay granules

or cat litter to the spill. Sweep up material for disposal

when absorption is completed and contain in a refuse

vessel for disposal (see STORAGE AND DISPOSAL section).

If necessary, wash the spill area with an alkali detergent and

water and absorb as above the wash liquid for disposal.

SAFETY DIRECTIONS

Harmful if swallowed.

Will irritate the eyes and skin. Avoid contact with

eyes and skin.

When preparing the spray, wear cotton overalls

buttoned to the neck and wrists, a washable hat,

elbow-length PVC gloves and a face shield or goggles.

If the product is in eyes, wash it out immediately

with water.

Wash hands after use.

After each day’s use, wash gloves, face shield or

goggles and contaminated clothing.

FIRST AID

If poisoning occurs contact a doctor or Poisons

Information Centre (Phone: Australia 13 11 26).

If in eyes, hold eyes open, flood with water for at least

15 minutes and see a doctor.
