6 GENERAL DESCRIPTION:

A post emergence, foliar absorbed, translocated grass-selective herbicide with little residual action. It is used on a very wide range of broad leaved crops for control of annual and perennial grasses.

7 APPLICATION METHODS AND TIPS:

Best results on young actively growing weeds sprayed in fine, mild weather with rain a day or two later.
Use higher rates of water in dry, warm or marginal conditions. See HerbiRate for determining the rate adjustment required to account for current conditions.
Higher rates are required after tillering of grasses.

8 WEATHER:

Rainfast in 1 hour.
Frost effects: Wait for weeds to begin actively growing after frosts for best results. If plants not damaged by frost then they are usually susceptible within a day. If plants have been severely damaged by frost then wait until till growth resumes and new leaves emerge. Frost a day or two after spraying generally has little effect.
Wind: Spray when wind is away from grass crops to avoid damage.
Inversions: Don't spray during inversions if grass crops are growing within 3 km or along cold air drainage lines.
Temperature: Higher rates may be required with at high temperatures
Delta T and relative humidity: Avoid application when Delta T is greater than
Moisture stressed weeds are relatively tolerant to fluazifop.
See HerbiRate for determining the rate adjustment required to account for current conditions.

9 ADJUVANTS:

Wetting agents: Not required with Fusilade Forte. For 212 g/L formulations use wetting agents (such as Agral or BS1000) on soft foliage crops and in warm conditions to reduce the risk of oil burn.
Spray oils: Not required with Fusilade Forte. For 212 g/L formulations use spray oils at 1-2% for maximum weed control.

10 WATER QUALITY:

Hard water: OK.
Salty water: OK.
Colloids: OK.
pH: Acidic water is OK. Highly alkaline water should be avoided or treated.
Tank life: 1 day in alkaline water to many weeks in rain water. If mixed product needs to be kept then add an acidifier.

11 COMPATIBILITY:

Trace elements.
See HerbiGuide Compatibilities button.

12 EQUIPMENT:

Boom sprays applying 30 - 100 L/ha with 110 degree flat fan nozzles producing droplets in the 150-200 micron VMD range at 150-400 kPa are common.
Aircraft applying 20 - 30 L/ha with 150-200 micron VMD droplets. (Syngenta recommends a minimum of 30 L/ha).
Hand spraying with hollow cone nozzles such as Spraying Systems D8 disc or Number 45 are suitable.
Use 100 mesh filters for smaller nozzles and 50 mesh for larger nozzle sizes.

13 SPRAYER DECONTAMINATION:

If the sprayer has been used for sulfonyl urea (e.g. chlorsulfuron or metsulfuron) or hormone herbicides (e.g. 2,4-D or MCPA) then it needs to be thoroughly cleaned before using fluazifop on broad leaved crops. Use the decontamination procedure for the product last used.

Clean Up:

Remove filters and nozzles and manually clean separately. Rinse with soapy water or water plus wetting agent and run through boom. Rinse with water.

Decontamination:

Remove the nozzles and screens and clean separately and allow to soak in a mixture of 500 mL chlorine bleach per 10 L water for at least 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. Fill with 1% solution of ammonia and allow to stand for several hours. Triple rinse with water. Or use a commercial spray tank and equipment cleaner.
Rinse nozzles and filters in water and replace.
Ensure equipment has been cleaned before moving on to spray cereal crops with other products.

14 HERBICIDE RESISTANCE:

Some populations of grasses are resistant to fluazifop.
Resistance is expected to occur after repeated applications.

* Stock destined for slaughter on the domestic market can be sold within the withholding period if they are put on clean feed for 7 days before slaughter. Stock for export markets should not eat treated pasture or feed within the withholding period and also require 7 days on untreated feed even after the withholding period before slaughter (i.e. the ESI).

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 pH, clay content and organic matter have little direct effect on performance. Poorer results may occur under waterlogged conditions.

20 MODE OF ACTION:

Inhibits acetyl coenzyme A carboxylase (ACC)
It interferes with energy (ATP) production and cell metabolism in susceptible species.
Post emergence with little residual activity.

Uptake and translocation:

Absorbed through leaves and green stems and translocated throughout the plant. Fluazifop-p is accumulated in the rhizomes and stolons of perennial grasses and the shoot and root meristems of annual and perennial grasses.
Translocation is rapidly reduced as plants become stressed.

Physiological effects:

Residual Life and Breakdown:

It has a half life in soil of 1-2 weeks.

21 SELECTIVITY:

Crop tolerance:

In hot conditions a transient oil burn may occur on soft foliage.
Canola occasionally show some damage to applications made after the 6 leaf stage.
Lupins may be sensitive at the budding to flowering stage.
Lucerne may be sensitive to applications before the 3 leaf stage.

Varietal sensitivities:

Effect on Clover Species:

Usually none but avoid spraying during flowering.

Effect on Medic Species:

Usually none but avoid spraying during flowering.

Effect on Lucerne:

Usually none but avoid spraying during flowering and before the 3 leaf stage of seedlings.

Effect on Native Plants:

Unusually none. Some species may show a transient oil burn.

22 DISEASE AND INSECT EFFECTS:

Disease and insect attack that reduces the growth rate or leaf area may lead to poorer control.
Sprayed Lupins may be slightly more susceptible to brown leaf spot infection.

23 PLANT SYMPTOMS:

Symptoms usually start to develop about 1 week after spraying with yellowing and or reddening of young leaves followed by tip death. Growing points turn brown and rot, shoot tips can be easily pulled out after 2-3 weeks. More mature leaves may remain green for extended periods before the grass eventually dies.
Fluazifop accumulates at the growing points, both above ground and in the roots, rhizomes and stolons of grasses.

SECONDARY EFFECTS:

25 TOXICITY SYMPTOMS:

Swallowing may cause nausea, vomiting and central nervous depression.
Solvent breathed in during ingestion or vomiting may cause bronchopneumonia, pulmonary oedema and lung scarring.
Repeated and long skin exposure may cause degreasing and contact dermatitis.
Inhalation may cause headaches, dizziness and nausea. High concentrations may cause central nervous system depression, loss of coordination, impaired judgement and eventual unconsciousness.

26 FIRST AID:

If SWALLOWED: Rinse mouth with water. Do NOT induce vomiting. Do NOT give anything by mouth to a semiconscious or unconscious patient. If vomiting occurs then position the patient to reduce the risk vomit entering lungs. Contact a doctor as solvent entering the lungs may cause problems.
If in EYES: Irrigate with plenty of water. See a doctor.
If on SKIN: Rinse with plenty of water, remove contaminated clothing, wash with soap and water.
If INHALED: Remove patient to fresh air. If breathing is laboured or patient is blue then administer oxygen. If breathing stops apply artificial respiration and see a doctor. If heart stops beating then apply external cardiac massage.
Advice to doctor: Treat symptomatically. Consider administering activated charcoal and a laxative. If gastric lavage is considered necessary, prevent aspiration of gastric material.
Contact the Poisons Information Centre on 131126.

27 ENVIRONMENTAL FATE:

Half life in soil: 1 - 14 weeks. Often less than a week in moist soil. Aerobic soil half life of 1 day compared to anearobic soil half life of 3 days. In Canada, herbicidal activity has been noted for 3-6 weeks after application depending on soil moisture and temperature.
Half life in water: 1 day to long.
It has an EPA classification for soil mobility that ranges from
Relatively low affinity for soil so it will move short distances but its soil mobility is reproted as low because it breaks down relatively quickly.
Ground water contamination: Unlikely.
Accumulation in milk and tissues.
pH stability:
Photolysis rate: Half-life of 6 days at 25 C in mid lattitude sun.
Hydrolysis half life: Half-life 29 hours at pH 9, 78 days pH 7, stable at pH 5
