13 SPRAYER DECONTAMINATION:

Clean Up:

Clean soon after spraying to reduce the risk of forming dried deposits that may be difficult to remove.

Remove filters and clean separately. Triple rinse with water or water plus 0.25% wetting agent and run through boom.

Decontamination:

Remove filters and clean separately.

Rinse with water and drain.

Quarter fill the tank with an alkali detergent (eg 500 mL or g of Drive, Dynamo, Omo, or Surf per 100 L water) and circulate for at least 15 minutes then run through boom. Rinse with water. Remove filters and clean separately. Replace them and rinse the whole system with water again.

24 TOXICITY:

Summary:

Low toxicity to mammals, birds, fish and aquatic organisms. Picloram residual may harm plants for many months after application.

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 - >4000 mg/kg (rabbit). Prolonged or repeated contact may cause moderate irritation or burn. may cause allergic skin reactions in some individuals.

Eye - May cause severe irritation with corneal injury which may result in permanent impairment of vision, even blindness. Chemical burns may occur.

Vapour inhalation - LC50 - Low. May cause irritation to upper respiratory tract

(nose and throat).

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

Not carcinogenic, mutagenic or teratogenic in animal studies (i.e. does not cause cancer or reproductive problems in animal tests).

Kidney and liver effects have been noted in animal studies.

Acceptable Daily Intake (ADI):

Does not accumulate in the body.

Acceptable Daily Intake (ADI):

Other Species:

Birds: LD50 >2000 mg/kg. LC50 >5000 ppm. Triclopyr is low toxicity. Picloram has low toxicity.

Fish: Triclopyr triethylamine salt is slightly toxic to fish and other aquatic organisms, LC50 10-100 mg/L, EC50 10-100 mg/L. In soil and water it breaks down to triclopyr acid which has low toxicity. Picloram has low toxicity with LC50 10-100 mg/L.

Invertebrates - Picloram is low toxicity, LC50 >100 mg/L, EC50 > 100 mg/L .

Bees: Triclopyr and picloram have low toxicity.

Arthropods: toxicity.

Earthworms:

Algae:

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

Accumulation: Triclopyr and picloram do not accumulate in animal systems.

25 TOXICITY SYMPTOMS:

26 FIRST AID:

If SWALLOWED: Contact a doctor immediately. Wash out mouth with water. Do not induce vomiting unless instructed by a doctor. Never give fluids or induce vomiting if the patient is unconscious or convulsing.

If in EYES: Hold eyelids open and wash eyes with plenty of water for 5 minutes, remove contact lenses if present and wash for a further 10 minutes. Obtain prompt medical consultation, preferably from an ophthalmologist.

If on SKIN: Remove contaminated clothing. Wash skin thoroughly with soap and water.

If INHALED: Remove patient to fresh air. See a doctor if symptoms persist.

If breathing difficulties occur seek medical attention immediately.

Advice to doctor: Treat symptomatically. Due to irritant properties, swallowing may result in burns/ulceration of mouth, stomach and lower gastrointestinal tract with subsequent stricture. Aspiration of vomitus may cause lung injury. Suggest endotracheal/esophageal control if lavage is done. If burn is present, treat as any thermal burn, after decontamination. No specific antidote. Treatment of exposure should be directed at the control of symptoms and the clinical condition of the patient.

27 ENVIRONMENTAL FATE:

Half life in soil: Picloram - weeks to months. Triclopyr - about 40 days.

Half life in water: 1-40 days for picloram and 1-2 days for triclopyr.

It has an EPA classification for soil mobility that ranges from

It has a leaching index of . (for comparison, trifluralin is 0-1 and chlorsulfuron is 25-30).

Ground water contamination:

Accumulation in milk and tissues:

pH stability:

Photolysis rate:

Hydrolysis half life: Picloram 1-40 days in water. Triclopyr 1-2 days.

Biodegradation rate: Triclopyr is high. Picloram is low.

Bioconcentration factor (BCF): Triclopyr <100. Picloram 100-3000.

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.

Accumulation in milk and tissues has not been found.
