3 ACTIVE INGREDIENTS: Halosulfuron 750g/L as dry flowable granules.4 CHEMICAL GROUP: B. Sulfonylurea Herbicide
5 RELATED HERBICIDES:Glean, Ally, Logran, Eclipse, and Broadstrike.
6 GENERAL DESCRIPTION:A translocated, residual herbicide for the control of Nutgrass and Mullumbimby Couch in Turf, Sugar Cane and Cotton.
7 APPLICATION METHODS AND TIPS:Apply to actively growing weeds when Nutgrass has 5 cm of new growth or Mullumbimby Couch has 2 cm of new growth. Repeat the application when regrowth reaches these levels.
Rainfall within 2 hours of application will reduce kill. Drought after application may also reduce kill.
Don't use treated turf clippings for mulch around desirable plants.
9 ADJUVANTS:Use a non ionic surfactant.
10 WATER QUALITY:Hard water
Tank life: One day.
11 COMPATIBILITY:14 HERBICIDE RESISTANCE:
Plants resistant to group B herbicides are expected to develop or be present.
15 REPLANTING INTERVALS:
16 WITHHOLDING PERIODS:
17 RE-ENTRY PERIOD:18 PROTECTIVE CLOTHING:
Wear safety goggles when handling granules.
Avoid breathing spray mist.
19 SOIL:20 MODE OF ACTION:
Inhibits the ALS enzyme.
Uptake and translocation:Leaf absorbed.
Physiological effects:Residual Life and Breakdown:
Effect on Clover Species:
Effect on Medic Species:
Effect on Lucerne:
Effect on Native Plants:
22 DISEASE AND INSECT EFFECTS:
23 PLANT SYMPTOMS:
Weeds show gradual yellowing of the leaves in 7-10 days followed by death. The full effect may take 4-6 weeks.
In cucurbits, crop injury may show as stunting, foliar bleaching and foliar epinasty a few days after emergence but the crop normally recovers after a week or two.
SECONDARY EFFECTS:24 TOXICITY:
Harmful if swallowed. Dust will irritate the eyes.
No significant adverse health effects are expected if less than a mouthful is swallowed.
In sulphite sensitive people skin reactions have been reported following dermal exposure. Respiratory reactions have been reported after eating food or inhaling medications containing sulphiting agents as preservatives. People with asthma may be more prone to these reactions.
Details:Mammalian toxicity - S5 poison.
Acute oral LD50 - 1287 mg/kg (rats). Slightly toxic. [For comparison table salt is 3000 mg/kg]
Acute dermal LD50 - > 5000 mg/kg (rabbit). Practically non toxic.
Skin - Slightly irritating. Not a sensitiser.
Eye - Mildly irritating. May cause redness, pain and tears.
Vapour inhalation - LC50 - > 5.7 mg/L air (rat). Practically non toxic. May cause respiratory tract irritation.
Chronic oral toxicity NOEL - 10-20 mg/kg for two years.
Not mutagenic or teratogenic (i.e. does not cause cancer or reproductive problems). At very high rates reduced fecundity has been noted in rabbits with a NOEL of 50 mg/kg during pregnancy.
Other Species - Birds - Practically non toxic. LD50 2250 - >5620 ppm
Fish - Slightly toxic LC50 > 21.4-26.7 ppm.
Invertebrates - slightly toxic. LC50 24 ppm
Bees - Practically non toxic. LD50 >100 ug/bee
Green Algae - Highly toxic. EC50 = 5.3 ppb
Duckweed - Very highly toxic. LC50 = 0.038 ppb
25 TOXICITY SYMPTOMS:26 FIRST AID: for Oral Intake:

Remove the nozzles and screens and clean separately.
Do not use chlorine bleach with ammonia cleaners or fertilisers containing ammonium because a toxic chlorine gas will be produced.
