6 GENERAL DESCRIPTION:

Pinoxaden is a post emergent, translocated, foliar absorbed, grass selective herbicide

7 APPLICATION METHODS AND TIPS:

Always apply with an oil based adjuvant. Agidor is recommended by the supplier at rates of 500 mL per 100 L spray mix when volumes of spraying are greater than 50 L/ha and at rates of 500 mL/ha when spray volumes are less than 50 L/ha. Other spray oils appear to be effective under good growing conditions but may be less effective under poor conditions.

Rainfastness - 30 minutes when applied with Agidor. May be longer with other spray oils.

Best results on actively growing weeds in fine, cool, weather with rain a few days later. Good control of Wild Oats and Phalaris from the 2 leaf to end of tillering stages and for Annual Ryegrass from the 2 leaf to early tillering stages. Early applications usually give greater crop yields than later applications.

10 WATER QUALITY:

Hard water

Colloids

pH

11 COMPATIBILITY:

See HerbiGuide Compatibilities button.

12 EQUIPMENT:

Boom - Apply with at least 20 L/ha water (label recommends > 50 L/ha) plus oil based adjuvant (e.g. Agidor) with nozzles producing 200-300 micron VMD droplets (ASAE fine to medium spray).

Aerial - Apply with at least 20 L/ha water plus an oil based adjuvant (e.g. Agidor) with equipment producing 200-250 micron VMD droplets. (label recommends 250-350 micron VMD droplets or ASAE medium spray)

13 SPRAYER DECONTAMINATION:

Wash inside the spray tank with water and drain. Fill tank to a quarter full and flush through pumps and nozzles. Remove and clean nozzles and filters. Fill tank to a quarter full and add 500 mL of liquid alkali detergent such as Omo, Surf or Drive per 100 litres of water. Agitate for 15 minutes. Flush through pumps and nozzles. Clean nozzles and strainers then rinse with another quarter tank of water.

14 HERBICIDE RESISTANCE:

Plants are likely to become resistant after multiple applications of group A herbicides.

Some populations of Annual Ryegrass that are resistant to group A Fop herbicides may still be susceptible to group A Den herbicides. Annual Ryegrass that is resistant to Group A Dim herbicides will probably also be resistant to Den herbicides like pinoxaden. Do not use on Dim resistant populations.

Do a resistance test to determine the true susceptibility.

Use in combination with a pre-emergent herbicide from a different mode of action group.

15 REPLANTING INTERVALS:

CropTime
AllNext season

Pinoxaden has a short half life in the soil and has limited root uptake so re planting a few weeks after spraying is not expected to cause crop damage (for example re planting after a crop failure).

16 WITHHOLDING PERIODS:

CropTypeTime
AllHarvest 
AllGrazing 


17 RE-ENTRY PERIOD:

After spray has dried. Wear gloves, cotton overalls and non absorbent boots if working in crop before the spray dries.

18 PROTECTIVE CLOTHING:

Cotton overalls, hat, non absorbent boots.

Use gloves and goggles when handling the concentrate.

19 SOIL:

20 MODE OF ACTION:

Pinoxaden inhibits the acetyl coenzyme A carboxylase which inhibits the production of fatty acids

Uptake and translocation:

Pinoxaden is absorbed mainly through the leaves and is translocated both up (acropetally) and down (basipetally) the plant to the growing shoot or root tips. When applied with methyl esters of Canola oil uptake is almost complete with an hour of application. With mineral oils uptake high levels of uptake may take 24 hours and when applied with wetting agents uptake may take more than 30 hours in Wild Oats. Without adjuvants uptake appears to plateau at about 10% of the applied product for Wild Oats.

There is limited root uptake.

Physiological effects:

Residual Life and Breakdown:

Selectivity:

Most broad-leaved plants and many grasses such as Wheat, Barley, Annual Poa, Barley Grass, Brome Grasses and many perennial grasses tolerate pinoxaden. Susceptible annual grasses are controlled at low rates.

May be applied to Wheat and Barley from the 2 leaf to flag leaf emergence growth stages.

23 PLANT SYMPTOMS:

Susceptible plants stop growing within 48 hours of absorbing pinoxaden. Discolouration of leaves and swelling usually occurs within 7-14 days and leaves can generally be easily pulled from their bases. Tissue death follows a week or two later. Final effects are usually evident by 6 weeks after treatment.

SECONDARY EFFECTS:

24 TOXICITY:

Summary:

Low toxicity to mammals, birds, insects and arthropods. Toxic to fish, aquatic organisms and algae.

Details:

Poison schedule - S5

Mammalian toxicity - Low

Acute oral - Low toxicity. LD50 >5000 mg/kg (rats) for active ingredient, LD50 = 3129 (female rat) for 100 EC formulation. [For comparison table salt is 3000 mg/kg]

Acute dermal - Low toxicity. LD50 > 2000 mg/kg (male & female rat) for active and 100 EC formulation.

Skin sensitisation - Active ingredient and 100 EC formulation are not skin sensitisers (guinea pig).

Skin - Active ingredient non-irritation. 100 EC formulation moderately irritating (rabbit).

Eye - Active ingredient irritating. 100 EC formulation mildly to moderately irritating (rabbit).

Vapour inhalation - Low toxicity. LC50 (4 hours) = 5.2 mg/L air (rat) for active ingredient and LC50 > 5 mg/L air (male & female rat) for 100 EC formulation.

Chronic oral toxicity NOEL - mg/kg for two years.

No evidence of carcinogenic, mutagenic teratogenic or reproductive effects.(i.e. does not cause cancer or reproductive problems).

Acceptable Daily Intake (ADI) -

The aromatic hydrocarbon may cause central nervous system depression and narcosis (drunkenness).

Other Species -

Birds - Low toxicity. LC50 for the 100 EC formulation is >5620 mg/kg.

Fish - toxic. LC50 (96 hours) = 5.6 mg/L Rainbow Trout. The active ingredient has low toxicity to aquatic organisms. The emulsifiable concentrate formulation (e.g. Axial) is toxic to aquatic organisms.

Invertebrates - toxic. EC50 (48 hours static) = 3.2 mg/L Water Flea (Daphnia magna)

Bees - toxicity.

Arthropods - Low toxicity.

Earthworms - The active ingredient has low toxicity with an LC50 > 1000 mg/kg soil. The 100 EC formulation has a LC50 = 8.2 mg/kg soil but is not expected to harm earthworms at normal use rates.

Algae - toxic. EBC50 (72 hours) = 4.6 mg/L, EC50 (72 hours) = 9.6 mg/L Green Algae (Pseudokirchneriella subcapitata).

25 TOXICITY SYMPTOMS:

26 FIRST AID:

If SWALLOWED - Do NOT induce vomiting. Seek medical advice.

If in EYES - Irrigate with plenty of water. Remove contact lenses. Immediate medical attention id required.

If on SKIN - Rinse with plenty of water, remove contaminated clothing, wash with soap and water. If skin irritation persists then see a doctor.

If INHALED - Remove patient to fresh air and keep warm and at rest. If breathing stops apply artificial respiration and call Poisons Information Centre on 13 11 26 immediately.

Advice to doctor - Treat symptomatically.

No cases of human poisoning are on record.


27 ENVIRONMENTAL FATE:

Half life in soil - < 1 day for active and the main metabolites have half lives of 1-16 days.

Half life in water - days at pH5 and 35 C.

Soil mobility - Pinoxaden is moderately mobile in the soil. Cloquintocet-mexyl is immobile in the soil.

Ground water contamination - Unlikely

Accumulation in milk and tissues - Not expected.

pH stability -

Pinoxaden and cloquintocet-mexyl are rapidly hydrolysed to primary metabolites that degrade by photolysis and microbial activity leading to mineralisation.

Photolysis rate - fast.

Hydrolysis half life - short.

Biodegradation rate - Pinoxaden and Cloquintocet-mexyl are not persistent in the soil or water and don't accumulate in the soil.

Bioaccumulation - Pinoxaden has a low potential for bioaccumulation. Cloquintocet-mexyl does not bioaccumulate.
