6 GENERAL DESCRIPTION:

A translocated, residual herbicide for the control of trees, regrowth and woody weeds in grass lands.

7 APPLICATION METHODS AND TIPS:

Avoid application near desirable trees or scrub.
Do not use within 100 metres of a water course, on erosion or salt prone areas or on land with a slope great than 20%.
Retain at least 20% of the original vegetation with wildlife corridors at least 100 metres wide.
Do not use on areas that may be cropped in the next 5 years.
Fire or burning of the pasture before the pellets have been washed into the soil will reduce the residual life of the product.
Use gloves for hand application.
Distribute pellets evenly over the area to 30 cm beyond the drip line of the tree or scrub.
Results are usually poorer on soils with high clay or organic matter content.
Application when grasses are dormant reduces the risk of damage to the pasture.
Poisonous plants may become more palatable after application. Remove stock until poison plants have died.
Aerial application can only be done by Dow AgroSciences approved applicators and should not be made in rainy or windy (>20 km/hr) conditions.

10 WATER QUALITY:

Not applicable.

11 COMPATIBILITY:

Not normally mixed with other products.

14 HERBICIDE RESISTANCE:

Some species are likely to develop resistance with repeated applications.

18 PROTECTIVE CLOTHING:

Use gloves if spreading by hand.

20 MODE OF ACTION:

Rainfall washes the herbicide into the root zone where it is absorbed by the roots of the target species. It usually lasts in the soil for several years.

Uptake and translocation:

Root absorbed and translocated.

Physiological effects:

Residual Life and Breakdown:

21 SELECTIVITY:

Crop tolerance:

High rates will kill some grasses especially native annual grasses.

Varietal sensitivities:

Effect on Clover Species:

Effect on Medic Species:

Effect on Lucerne:

Effect on Native Plants:

22 DISEASE AND INSECT EFFECTS:

23 PLANT SYMPTOMS:

Woody weeds may loose all their foliage, regrow and be defoliated again several times before they die. Some species may take 2 years to control.

SECONDARY EFFECTS:

24 TOXICITY:

Summary:

Low toxicity and hazard. Not a scheduled poison.

Details:

Mammalian toxicity -
Acute oral LD50 - >2000 mg/kg (rats), [For comparison table salt is 3000 mg/kg]
Acute dermal LD50 - >2000 mg/kg (rabbit).
Skin - Low toxicity.
Eye - Moderately irritating.
Vapour inhalation - Low risk because of pellet formulation.
Chronic oral toxicity NOEL - ppm for two years.
Not mutagenic or teratogenic (i.e. does not cause cancer or reproductive problems).

Other Species -

Birds - low toxicity.
Fish - low toxicity LC50 > ppm.
Invertebrates - low toxicity.
Bees - not toxic.
Blue green algae - slight toxicity.

25 TOXICITY SYMPTOMS:

26 FIRST AID:

Contact a doctor or Poisons Information Centre on 13 11 26.
Don't give fluids or induce vomiting if the patient is unconscious or convulsing.
If Swallowed - Contact a doctor immediately.
If on Skin - Wash skin thoroughly with soap and water.
If in Eyes - Flush with water for 15 minutes.
If Inhaled - remove patient from contaminated area to fresh air.
Advice to doctor - Treat symptomatically.

27 ENVIRONMENTAL FATE:

It has a half life in soil of 12-15 months. It may leach up to 60 cm. Small amounts may run off in surface water.
It has an EPA classification for soil mobility that ranges from
Ground water contamination is unlikely.
Replanting intervals - Up to 5 years.
Accumulation in milk and tissues - Does not accumulate.
Does not bioaccumulate in the animal systems.
