6 GENERAL DESCRIPTION:

A translocated, residual herbicide for the control of woody weeds.

7 APPLICATION METHODS AND TIPS:

Best results when plants are actively growing.

Apply to dry plants.

Maximum tank storage time - 1 week.

9 ADJUVANTS:

Spray oils may improve weed control but may reduce selectivity on the crop.

10 WATER QUALITY:

11 COMPATIBILITY:

See HerbiGuide.

14 HERBICIDE RESISTANCE:

Unlikely to occur under normal use patterns. However, there may be populations of weeds that have or will develop resistance.

18 PROTECTIVE CLOTHING:

Cotton overalls, washable hat, elbow length neoprene gloves and face shield or goggles.

RE ENTRY PERIOD.

Wear protective clothing until the spray has dried.

20 MODE OF ACTION:

Uptake and translocation:

Absorbed through roots, leaves, bark or from the cut stump.

Physiological effects:

Hormone herbicide with wide ranging effects. Disrupts plant cell growth.

Residual Life and Breakdown:

Selectivity:

Broad leaf species are generally more sensitive than grass species.

23 PLANT SYMPTOMS:

Leaves usually turn red within a few weeks of application then fall off.

SECONDARY EFFECTS:

24 TOXICITY:

Summary:

Harmful if swallowed. Will irritate eyes, nose, throat and skin.

Details:

Poison Schedule - S6

Mammalian toxicity - Low.

Acute oral LD50 - >2000 mg/kg (rats), [For comparison table salt is 3000 mg/kg].

Skin - Acute dermal LD50 - > 2000 mg/kg (rabbit). Prolonged or repeated contact may cause moderate irritation or burn.

Eye - May cause temporary, moderate eye irritation.

Vapour inhalation - LC50 - Low. Excessive exposure to solvent inhalation may cause eye and respiratory irritation, headache, dizziness and narcotic effects.

Chronic oral toxicity NOEL (picloram) - 0.5-7 mg/kg/day for two years.

Not mutagenic or teratogenic (i.e. does not cause cancer or reproductive problems).

Does not accumulate in the body.

Other Species -

Birds - Triclopyr has slight to low toxicity. Picloram has low toxicity.

Fish - Triclopyr butoxyethyl ester is toxic to fish and moderately toxic to other aquatic organisms. In soil and water it breaks down to triclopyr acid which has low toxicity. Picloram has low toxicity.

Invertebrates - toxicity.

Bees - Triclopyr and picloram have low toxicity.

Livestock - Triclopyr butoxyethyl ester is moderately toxic to livestock. In soil and water it breaks down to triclopyr acid which has low toxicity.

Triclopyr and picloram do not accumulate in animal systems.

25 TOXICITY SYMPTOMS:

26 FIRST AID:

Contact a doctor or Poisons Information Centre on 13 11 26.

If Swallowed - Contact a doctor immediately. Do not induce vomiting unless instructed by a doctor. Never give fluids or induce vomiting if the patient is unconscious or convulsing.

If on Skin - Wash skin thoroughly with soap and water.

If in Eyes - Flush with water for 15 minutes. See a doctor.

If Inhaled - Remove patient from contaminated area to fresh air.

Advice to Doctor

Treat symptomatically with supportive care.

27 ENVIRONMENTAL FATE:

Picloram ester and triclopyr ester are rapidly converted to the parent acids in soil, water, plants and animals.

Picloram is more residual than triclopyr.

Picloram has a half life in water of 1 to 40 days in water depending mainly on sunlight intensity. It is broken down in water by ultra violet radiation and is stable to hydrolysis at neutral to alkaline pH. It is broken down in soil by photo degradation and microbial action and has a half life in soil ranging from weeks to months. It normally remains in the top 30 cm of soil but may be found deeper on soils with poor adsorption properties.

Triclopyr decomposes in water with a half life of 1 to 2 days. It is broken down in soil by photo decomposition and microbial action and has a half life in soil of about 40 days. Minimal leaching may occur on light soils in high rainfall conditions.

It has an EPA classification for soil mobility that ranges from

Ground water contamination is possible.

It is stable in intact plants.

It can move in run-off water after heavy rainfall events as it dissolves in water rather than attaching to soil particles.

Replanting intervals - 12 months for most species to 4 years for some species. Accumulation in milk and tissues has not been found.

31 PROPERTIES:

Water solubility at 25 C. - emulsifiable

Oil solubility - Soluble? Not normally mixed with oils.

Octanol:Water ratio at 25 C. - at pH 5;

Vapour Pressure

picloram acid 6.15 x 10^-7 mm Hg at 35⁰C

triclopyr butoxyethyl ester 1.0 x 10^-5 mm Hg at 33⁰C

solvents 0.14 mm Hg at 20⁰C.

Dissociation constant - pKa

Melting point - C.

Boiling Point - 183-210C (solvent)

Molecular weight -

Half life in water - 1-40 days.

Not corrosive
