6 GENERAL DESCRIPTION:An agricultural herbicide for the control of broad-leaved weeds in leguminous and triazine tolerant crops.
7 APPLICATION METHODS AND TIPS:Best results when applied in fine weather, before weeds emerge or when they are very young and actively growing and rain follows a few days later.
High rates on very alkaline soils (pH>8) may cause crop damage.
Consider residual herbicide from previous triazine applications as this may be additive and damage crop.
Use lower rates on sandy soils and higher rates on heavy soils.
Some crop yellowing may occur after application.
Do not apply to waterlogged soil or if heavy rain expected within 2 days.
Avoid using in cloddy or high trash areas or where deep furrows are left by planting equipment.
Add 1% spray oil for control of weeds that have emerged.
Sow grain legumes 3-5 cm deep.
Don't use within 60 m of water bodies.
8 WEATHER:Rainfast in probably 4 hours for post em applications. Rain improves pre em applications.
Frost effects: No effect on pre em applications. Reduced efficacy for post em applications.
Inversions: Avoid application during low level inversions as excessive drift may occur.
Delta T and relative humidity: Avoid post em applications when Delta T is greater than
9 ADJUVANTS:Wetting agents:
Spray oils: Use for post emergent applications
10 WATER QUALITY:Hard water: Little effect.
Salty water: Little effect.
Colloids: Little effect.
Tank life: Long. Probably weeks.
11 COMPATIBILITY:Trace elements.
See HerbiGuide Compatibilities button.
12 EQUIPMENT:Boom sprays:
Carrier volume: 30-200 L/ha.
Nozzles: Flat fan.
Pressure: 150-400 kPa.
Droplet size: Coarse droplets recommended on the label. Use finer droplets for post em sprays.
Aerial application:Carrier volume: 30 L/ha.
13 SPRAYER DECONTAMINATION:Clean Up:
Clean soon after spraying to reduce the risk of forming dried deposits that may be difficult to remove. Mechanically removed any caked deposits.
Remove filters and clean separately. Rinse with soapy water (eg 500 mL or g of Drive, Dynamo, Omo or Surf per 100 L water) or water plus 0.25% wetting agent and run through boom. Rinse with water.
Decontamination:Remove filters and clean then soak in 500 mL household ammonia in 10 L water for 30 minutes.
Rinse sprayer with soapy water (eg 500 mL or g of Drive, Dynamo, Omo or Surf per 100 L water) or water plus 0.25% wetting agent and run through boom. Add 1 L of household ammonia (3% active ingredient) per 100 L water while filling the tank. Circulate through the system and spray a small quantity through the boom then allow to stand for several hours. Rinse with soapy water or water plus 0.25% wetting agent. Rinse with water. Or use a commercial spray tank and equipment cleaner.
Rinse nozzles and filters in water and replace then rinse the whole system with water again.
14 HERBICIDE RESISTANCE:Tolerant plants are expected to occur and may dominate the weed population after repeated applications.
15 REPLANTING INTERVALS:
|All that are not on label||>6 months|
16 WITHHOLDING PERIODS:
17 RE-ENTRY PERIOD:8 days.
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: Use lower rates in light soils and higher rates in heavy soils.
Soil pH: More active in very alkaline soils with pH>8 and crop damage may occur.
Soil organic matter: High levels may absorb herbicide and increase breakdown and thus reduce the level of weed control.
Soil moisture at application: Moist soil is require for the good results.
20 MODE OF ACTION:Inhibitor of photosynthesis at photosystem II
Uptake and translocation:Absorbed mainly through the roots, with some leaf uptake. Translocated within the plant.
Residual Life and Breakdown:Microbial breakdown and hydrolysis.
21 SELECTIVITY:Crop tolerance:
Effect on Clover Species:
Effect on Medic Species:Damages medics.
Effect on Lucerne:Damages young lucerne
Effect on Native Plants:Probably reasonably tolerant.
22 DISEASE AND INSECT EFFECTS:23 PLANT SYMPTOMS:
Yellowing followed by death.
SECONDARY EFFECTS:24 TOXICITY:
Harmful if swallowed.
Details:Poison schedule: S6
Acute oral LD50: 1590-2000 mg/kg (rat), [For comparison table salt is 3000 mg/kg]
Acute dermal LD50: >2000 mg/kg (rabbit).
Skin: May be irritating. Not sensitizing.
Eye: Mildly irritating.
Vapour inhalation: LC50 > mg/L air (rat). Long term inhalation of high amounts of dust may overload lung clearance mechanism. Available data indicates that this product is not harmful. Product is unlikely to cause any discomfort or irritation.
Studies showed some increase in tumours in animals exposed to terbuthylazine at high dose levels but overall it is unlikely to be carcinogenic to humans. It can cause developmental or reproductive effects however these are generally at lower doses than maternal toxic effects and it is not genotoxic or teratogenic.
Chronic oral toxicity: for two years.
Acceptable Daily Intake (ADI): 0.003 mg/kg/day.
NOEL: 0.35 mg/kg/day
In mammals: following oral administration, 722-84% is eliminated in the urine and faeces within 24 hours, and almost all within 48 hours. A de-ethyl metabolite forms rapidly, followed by conjugates of products formed by oxidation of one methyl group of the tert-butyl type. All are rapidly excreted.
Other Species: Birds: Low toxicity. LD50 >1000 mg/kg Ducks and quail.
Eight day dietary LD50 for ducks and quail >5620ppm
Fish: toxicity: LC50 (96hr) for rainbow trout 3.8-4.6, Bluegill sunfish 7.5, carp and catfish 7.0 mg/L.
Invertebrates: toxicity. Daphnia LC50 (48hr) 21-50.9 mg/L
Bees: Low toxicity. LD50 (oral and contact) >100µg/bee
Earthworms: LC50 (7 day) >200 mg/kg soil
Algae: LC50 (72hr) 0.016-0.024 mg/L
25 TOXICITY SYMPTOMS:26 FIRST AID:
Not normally required.
If SWALLOWED: Wash out mouth with water. Do NOT induce vomiting. Do NOT give anything by mouth to a semiconscious or unconscious patient.
If in EYES: Hold eyelids open and wash eyes with plenty of water.
If on SKIN: Remove contaminated clothing. Wash 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:Half life in soil: 30-60 days.
Half life in water: days at pH5 and 35 C.
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: Possible.
Accumulation in milk and tissues: Not expected.
Hydrolysis half life:
Bioconcentration factor (BCF):
Plants: Triazine-tolerate plants (eg maize) rapidly de-chlorinate terbuthylazine to hydroxy terbuthylazine. Various amounts of de-ethylated and hydroxy de-ethylated terbuthylazine are produced, depending on the plant species.
Soil/Environment: Adsorption onto soils is strong; Koc 162-278, Kd 2.2-25 are typical values for light agricultural soils. Terbuthylazine is only slightly mobile. Microbial degradation proceeds mainly by de-ethylation and hydroxylation with eventual ring cleavage. DT50 30-60 days in biologically active soil.
