3 ACTIVE INGREDIENTS: Isoxaben 750 g/kg4 CHEMICAL GROUP: OBenzamide group. Inhibitors of cellulose synthesis.
5 RELATED HERBICIDES:
|Casoron||Dichlobenil 67.5g/kg (or 40g/kg)|

6 GENERAL DESCRIPTION:A selective pre emergence herbicide for control of some broad-leaved weeds in orchards, vineyards, plantations and Pyrethrum.
7 APPLICATION METHODS AND TIPS:Requires 10 mm rain within 3 weeks of application to activate the herbicide.
Best results on bare soil that is free of clods, trash and established weeds when soil is moist and rain follows soon after.
Poor coverage of the soil surface may result in poor weed control.
Avoid spraying if heavy rain that is likely to cause runoff is predicted within 24 hours.
Keep agitated in spray tank as the product may settle out.
8 WEATHER:Rainfast almost immediately.
Frost effects: None expected.
Inversions: Avoid spraying during low level inversions to reduce the risk of drift onto adjacent areas.
Temperature: No effects expected.
Delta T and relative humidity: Avoid application when Delta T is greater than
Soil moisture at application: Best results on moist soil. Avoid applying to dry soil.
9 ADJUVANTS:Wetting agents: None required.
Spray oils: None required.
10 WATER QUALITY:Hard water:
Tank life: Product tends to settle out if left in the tank without agitation.
11 COMPATIBILITY:Trace elements.
See HerbiGuide Compatibilities button.
12 EQUIPMENT:Boom sprays:
Carrier volume: 200-450 L/ha recommended on label. Lower volumes are acceptable providing good coverage of soil is achieved.
Nozzles: Flat fan. 50 mesh or greater screens.
Pressure: 150-400 kPa.
Medium spray quality recommended on label. Use finer sprays if using low carrier volumes.
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. Triple rinse with water or water plus 0.25% wetting agent and run through boom.
Remove filters and clean separately.
Rinse with water and drain.
Quarter fill the tank with an alkali detergent (eg 500 mL or g of Drive, Dynamo, Omo, or Surf per 100 L water) and circulate for at least 15 minutes then run through boom. Rinse twice with water.
14 HERBICIDE RESISTANCE:Tolerant plants are expected to occur and may dominate the weed population after repeated applications.
15 REPLANTING INTERVALS:
|Brassica crops||3 years|
|Other broad-leaved crops from seed||2 years|
16 WITHHOLDING PERIODS:
|Pyrethrum||Harvest||Not required when used as directed|
|All||Harvest||Not required when used as directed|
|All other crops||Grazing||Not required when used as directed|
17 RE-ENTRY PERIOD:Wear protective clothing if in prolonged 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:
Soil organic matter:
20 MODE OF ACTION:Inhibits cellulose synthesis.
Uptake and translocation:Root absorbed.
Physiological effects:Residual Life and Breakdown:
Long residual life.
21 SELECTIVITY:Has little effect on grasses.
Crop tolerance:Well tolerated by emerged plants and grasses from seed.
Varietal sensitivities:Effect on Clover Species:
Kills clover germinating from seed.
Effect on Medic Species:Kills Medic germinating from seed.
Effect on Lucerne:Kills lucerne germinating from seed.
Effect on Native Plants:Established native plants are generally tolerant. It is expected to kill a range of broad-leaved native plants germinating from seed.
22 DISEASE AND INSECT EFFECTS:None expected.
23 PLANT SYMPTOMS:SECONDARY EFFECTS:
Low mammalian toxicity.
Will irritate eyes and skin.
Possible risk of impaired fertility.
Details:Poison schedule: S5.
Mammalian toxicity: Low
Acute oral LD50: 5000 mg/kg (rat), [For comparison table salt is 3000 mg/kg]. Harmful effects not anticipated from swallowing small amounts.
Acute dermal LD50: >5000 mg/kg (rabbit).
Skin: Prolonged or repeated exposure may cause slight irritation. Prolonged skin contact is unlikely to result in absorption of harmful amounts.
Eye: May cause moderate eye irritation, which may be slow to heal. May cause slight temporary corneal injury.
Vapour inhalation: LC50 > mg/L air (rat).
Chronic oral toxicity: NOEL mg/kg for two years.
Isoxaben caused birth defects in laboratory animals only at doses toxic to the mother. An increase in non-malignant liver tumours was observed with isoxaben in one of two species tested. May contain trace amounts of silica which is suspected to be a carcinogen.
Isoxaben has been shown to interfere with reproduction in animal studies.
In-vitro and animal genetic toxicity studies were negative for mutagenicity.
Acceptable Daily Intake (ADI):
Contains component(s), which, in animals, have been shown to cause liver and kidney effects. May contain trace amounts of silica. Repeated excessive exposure to crystalline silica may cause silicosis, a progressive and disabling disease of the lungs. Some evidence suggests that kidney effects may also result from excessive exposure.
Other Species:Highly toxic to aquatic plants.
Fish: toxicity LC50 > mg/L.
Not expected to be acutely toxic to aquatic fauna. EC50 is above the water solubility.
25 TOXICITY SYMPTOMS:26 FIRST AID:
If SWALLOWED: Do NOT give anything by mouth to a semiconscious or unconscious patient. No specific treatment required.
If in EYES: Irrigate with plenty of water, remove contact lenses, if present, after the first 5 minutes, then continue flushing eyes for at least 15 minutes. Obtain medical attention without delay, preferably from an ophthalmologist.
If on SKIN: Rinse with plenty of water, remove contaminated clothing, wash with soap and water.
If INHALED: Remove patient to fresh air. See a doctor.
Advice to doctor: Treat symptomatically.
