6 GENERAL DESCRIPTION:

A translocated, foliar and root absorbed, residual, agricultural herbicide that is used as a mixing partner with knockdown herbicides for range of crops or alone in orchard, vineyard and industrial weed control situations. Women of child bearing age are advised not to mix load or spray it as birth defects have been observed in tests on laboratory animals.

7 APPLICATION METHODS AND TIPS:

Best results on actively growing weeds.

8 WEATHER:

Rainfast in hours.

Frost effects:

Wind:

Inversions: Avoid application during low level inversions as excessive drift may occur.

Temperature:

Delta T and relative humidity: Avoid application when Delta T is greater than

A 15 m downwind buffer zone is required.

9 ADJUVANTS:

Wetting agents:

Spray oils: Use a spray oil for most applications.

10 WATER QUALITY:

Tank life: Long.

11 COMPATIBILITY:

Trace elements.

See HerbiGuide Compatibilities button.

12 EQUIPMENT:

Boom sprays:

Carrier volume: 50-500 L/ha

Nozzles: Flat fan.

Pressure: 150-400 kPa.

Droplet size: Fine to medium preferred.

Aerial application:

Carrier volume: 30 L/ha

Not normally applied by air.

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 (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. Fill with 1 litre of 3% household ammonia per 100 litres of water and circulate for at least 15 minutes (leave 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.

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, mask and face shield when handling the concentrate. Avoid inhaling mist.

20 MODE OF ACTION:

It is a diphenyl ether group G herbicide that inhibits protoporphyrinogen oxidase.

Flumioxazin is a light-dependent peroxidising herbicide (LDPH), which acts by blocking heme and chlorophyll biosynthesis resulting in the accumulation of photo-toxic porphyrins.

24 TOXICITY:

Summary:

Women of child bearing age are advised not to mix load or spray it as birth defects have been observed in tests on laboratory animals. They should keep out of areas being sprayed.

Otherwise low toxicity.

Details:

Poison schedule: S7

Mammalian toxicity:

Acute oral LD50: >5000 mg/kg (rat), Not harmful. [For comparison table salt is 3000 mg/kg]

Acute dermal LD50: >2000 mg/kg (rabbit). Skin contact is not expected to be harmful.

Skin: Slight irritant. Not a sensitiser.

Eye: Slight irritant.

Vapour inhalation: LC50 >0.969 mg/L air (rat). Inhalation of vapour is likely to b harmful.

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

Not carcinogenic in animal studies (i.e. does not cause cancer in animal tests).

CHRONIC HEALTH EFFECTS (Active Ingredient)

Repeated exposures to flumioxazin technical in animals have produced anaemia and other blood formation changes, organ weight changes and changes in blood chemistry. Flumioxazin technical did not produce cancer in lifetime feeding studies in laboratory animals. Birth defects were produced in the offspring of female rats exposed to flumioxazin technical at doses greater than 30 mg/kg bw/day. No developmental effects were observed in rabbits. Reproductive effects were observed in rats exposed to flumioxazin technical at greater than 100ppm in the diet.

OTHER TOXICOLOGICAL INFORMATION (Active Ingredient)

Reproduction Information

Acceptable Daily Intake (ADI):

Rats excrete flumioxazin in urine and faeces, with 97% cleared in 7 days.
