6 GENERAL DESCRIPTION:

A post emergence, leaf absorbed, short residual, selective agricultural herbicide applied as spray mainly for the control of broad-leaved weeds in cereal crops.

7 APPLICATION METHODS AND TIPS:

Best results in fine weather on young actively growing plants.

Good soil moisture is required before and after application.

No spray zones of 20 m upwind from sensitive water bodies apply.

8 WEATHER:

Rainfast in 4 hours according to the label but usually is much less and likely to be more like 1 hour in most situations.

Frost effects: Poorer weed control on frost affected plants.

Wind: No specific effect.

Inversions: Avoid spraying during inversions to reduce the risk of damage due to drift.

Temperature: Generally works better in warmer temperatures.

Delta T and relative humidity:

9 ADJUVANTS:

Wetting agents: Use a non ionic wetter on hard to wet weeds.

Spray oils: Do not use oils or more crop damage may occur.

10 WATER QUALITY:

Hard water: Very hard water may cause the herbicide to separate from the water.

Salty water: Similar to hard water.

Colloids:

pH:

Tank life: Days.

11 COMPATIBILITY:

Trace elements. Likely to be antagonistic.

See HerbiGuide Compatibilities button.

12 EQUIPMENT:

Boom sprays:

Carrier volume: 30-1000 L/ha. 50-150 L/ha on label.

Nozzles: Flat fan.

Pressure: 150-400 kPa.

Droplet size: 200 micron is good for low water volumes. Larger droplets are OK if higher water volumes are used. Label says use coarse droplets with more than 75 L/ha water.

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.

Remove filters and clean separately. Rinse with soapy water (e.g. 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 (e.g. 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. Fill with 1 litre of 3% household ammonia per 100 litres of water and circulate for at least 15 minutes (allow to stand for several hours if possible). Triple 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.

Don't use chlorine based cleaners in combination with ammonia.

14 HERBICIDE RESISTANCE:

Tolerant plants are expected to occur and may dominate the weed population after repeated applications.

15 REPLANTING INTERVALS:

CropTime
Brassica types e.g. Canola12 months? And cultivate.
CerealsA week or two.
Fabaceae cropsNot expected to be long. Do a test strip.

16 WITHHOLDING PERIODS:

CropTypeTime
AllGrazing6 weeks
AllHarvestNot required

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: No specific effect.

Soil pH: No specific effect.

Soil organic matter: No specific effect.

Soil moisture at application: Best result when soil is moist before and after application.

20 MODE OF ACTION:

Contains active ingredients from the nitrile, aryloxypicolinamide and phenoxy groups of herbicides. These act by inhibiting photosynthesis at photosystem II, carotenoid biosynthesis and disruption of plant cell growth.

See individual components for more detailed mode of action information.

Uptake and translocation:

Foliar absorbed with very minor root absorption. Translocated both up and down the plant.

Physiological effects:

Residual Life and Breakdown:

The picolinafen component may be residual for a few weeks.

21 SELECTIVITY:

Crop tolerance:

Temporary yellowing may occur.

Wilting may occur in some crops when it is mixed with dicamba

Varietal sensitivities:

Calingiri wheat is sensitive to some of the components of this mix.

Effect on Clover Species:

Soft on clovers. Damage is more common where Group C herbicides like atrazine or simazine have been used.

Effect on Medic Species:

Expect some damage. Damage is more common where Group C herbicides like atrazine or simazine have been used.

Effect on Lucerne:

Established plants are tolerant but seedlings may be damaged. Damage is more common where Group C herbicides like atrazine or simazine have been used.

Effect on Native Plants:

Soft on most established native plants.

22 DISEASE AND INSECT EFFECTS:

23 PLANT SYMPTOMS:

Yellowing and yellow blotches on the leaves.

SECONDARY EFFECTS:

24 TOXICITY:

Summary:

Product is poisonous if inhaled or swallowed. Will damage the eyes. Will irritate the skin. Repeated exposure may cause allergic disorders. Toxic to algae.

Details:

SUSMP classification (Poison schedule): S6.

Mammalian toxicity: Moderate toxicity.

Acute oral LD50:

LD50 (rat) 238 mg/kg for bromoxynil octanoate

LD50 (rat) 1300 mg/kg for MCPA 2EHE

LD50 (rat) >5000 mg/kg for picolinafen

[For comparison table salt is 3000 mg/kg]

Acute dermal LD50:

LD50 (rat) >2000 mg/kg for bromoxynil octanoate and MCPA 2EHE

LD50 (rat) >4000 mg/kg for picolinafen

Skin: Mild to moderate irritant. May irritate the skin. Bromoxynil octanoate is a sensitiser.

Prolonged contact with the concentrate can cause defatting of the skin and may result in dermatitis.

Eye: Irritating.

Vapour inhalation:

LC50 (rat) (4hr) 0.72 mg/L for bromoxynil octanoate

LC50 (rat) (4hr) >3.1 mg/L for MCPA 2EHE

LC50 (rat) (4hr) >5.9 mg/L for picolinafen

Do not inhale spray mist.

Some components classed as H351 Suspected of causing cancer.

Bromoxynil octanoate has been assigned R63 on the basis of studies, in rats, rabbits and mice which show reduced ossification and increased incidence of supernumerary ribs at doses (range 5-15 mg/kg/day) which are not toxic maternally. Supernumerary ribs are seen in control animals and are often seen in

reproductive toxicity studies. The ribs disappear during subsequent development with rats, but not with mice. The significance of supernumerary ribs as an indicator of developmental toxicity and extrapolation to other species remain problematical.

Chronic oral toxicity: Chronic overexposure may result in weight loss and damage to liver and kidneys.

NOEL for bromoxynil is 0.3 mg/kg/day for two years.

NOEL for MCPA is 1.1 mg/kg/day for two years.

NOEL for picolinafen is 1.4 mg/kg/day for two years.

Acceptable Daily Intake (ADI):

0.003 mg/kg/day for bromoxynil.

0.01 mg/kg/day for MCPA.

0.007 mg/kg/day for picolinafen.


Other Species:

Birds: Variable toxicity. LD50 bobwhite quail 170 mg/kg; mallard duck 2350 mg/kg for bromoxynil octanoate.

Fish: High toxicity LC50(96 hr, rainbow trout) = 0.041 mg/L for bromoxynil octanoate. LC50 (96 hr, bluegill sunfish) = 0.06 mg/L for bromoxynil octanoate.

Invertebrates: High toxicity. LC50(48 hr, Daphnia magna) = 0.046 mg/L for bromoxynil octanoate.

Bees: Not toxic. LD50 >100 ug/bee.

Earthworms:

Algae: High toxicity. EC50(96 hr) = 0.00018 mg/L for picolinafen.

EC50 (96 h) Desmodesmus subspicatus 1 mg/L for bromoxynil octanoate.

25 TOXICITY SYMPTOMS:

Headache, nausea, dizziness and weakness.

If breathed into the lung, e.g. from vomiting, the solvents and surfactants may result in chemical pneumonitis or other lung damage.

Prolonged skin exposure may cause dermatitis and defatting of the skin.

Weight loss and damage to the kidneys and liver may result from chronic over exposure.

26 FIRST AID:

If SWALLOWED: Wash out mouth with water. Do NOT induce vomiting. Do NOT give anything by mouth to a semiconscious or unconscious patient. If substantial amounts (more than 15 mL) of the concentrate have been swallowed AND if medical assistance is more than 30 minutes away, then induction of vomiting should be considered, preferably based on MEDICAL ADVICE if a physician can be contacted by phone. All care must be taken to prevent vomit from being inhaled.

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. If vomiting occurs, solvent and surfactants present may cause pulmonary pneumonitis.
