6 GENERAL DESCRIPTION:A translocated, residual, foliar and root absorbed 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.
Toxic plants may become more palatable after treatment.
8 WEATHER:Rainfast in 1 hour.
Inversions: Avoid application during low level inversions as excessive drift may occur.
Delta T and relative humidity: Avoid application when Delta T is greater than
9 ADJUVANTS:Not normally required.
Wetting agents: Organosilicone wetting agents are useful on some woody weeds.
Spray oils: May improve weed control especially for summer applications but may reduce selectivity on the crop.
10 WATER QUALITY:Hard water:
Tank life: Approximately 1 week.
11 COMPATIBILITY:Trace elements.
12 EQUIPMENT:Boom sprays:
Carrier volume: 50-500 L/ha.
Nozzles: Flat fan.
Pressure: 150-400 kPa.
Droplet size: 200-300 micron VMD.
High volume hand spraying:Carrier volume: 3000-4000 L/ha on label. Down to 500 L/ha is OK if coverage is even and finer droplets used.
Nozzles: Number 6-8 on label. 4-8 are OK.
Pressure: 700-1500 kPa on label. 200-1500 kPa is OK.
Droplet size: 200-350 micron VMD.
Aerial application:Carrier volume: 200 L/ha using 2 passes at 100 L/ha. Lower rates have been used successfully in some situations.
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.
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.
Chlorine based cleaners are NOT recommended.
14 HERBICIDE RESISTANCE:Unlikely to occur under normal use patterns. However, there may be populations of weeds that have or will develop resistance.
15 REPLANTING INTERVALS:Replanting intervals - 12 months for most species to 4 years for some species.
16 WITHHOLDING PERIODS:
17 RE-ENTRY PERIOD:Wear protective clothing if in contact with the crop before the spray has dried.
18 PROTECTIVE CLOTHING:Overalls, boots and washable hat. Use gloves and face shield when handling the concentrate.
19 SOIL:Soil texture: May leach on very sandy soils under high rainfall.
Soil pH: Little effect
Soil organic matter: Breaks down more quickly in high organic matter soils.
Soil moisture at application: Reduced weed control if plants are stressed due to very wet or very dry soil.
20 MODE OF ACTION:Disrupts cell growth.
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:21 SELECTIVITY:
Broad leaf species are generally more sensitive than grass species.
Crop tolerance:Varietal sensitivities:
Effect on Clover Species:
Effect on Medic Species:Damages medics.
Effect on Lucerne:Damages Lucerne
Effect on Native Plants:Damages most native plants at high rates. Very low can sometimes provide useful selective control of some weeds.
22 DISEASE AND INSECT EFFECTS:23 PLANT SYMPTOMS:
Leaves usually turn red within a few weeks of application then fall off.
SECONDARY EFFECTS:24 TOXICITY:
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 carcinogenic, mutagenic or teratogenic in animal studies (i.e. does not cause cancer or reproductive problems in animal tests).
Acceptable Daily Intake (ADI):
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.
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. See a doctor if symptoms persist.
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.
Advice to doctor: Treat symptomatically.
Contact the Poisons Information Centre on 131126.
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.
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:
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.
