6 GENERAL DESCRIPTION:A post emergence, translocated, grass selective herbicide for broad leaved crops.
7 APPLICATION METHODS AND TIPS:Use a spray oil.
Best results in fine weather, on young actively growing plants.
Add extra Dim herbicide if Annual Ryegrass is Fop tolerant and Dim susceptible.
8 WEATHER:Rainfast in 1 hour.
Temperature: Poorer efficacy on weeds that are stressed by very high or very low temperatures.
Delta T and relative humidity: Avoid application when Delta T is greater than
Soil moisture at application: Poorer weed control where weeds are stressed due to dry conditions or waterlogging.
9 ADJUVANTS:Wetting agents:
Spray oils: Use a 1 L spray oil per 100 L spray mix. Hasten, Kwickin and Uptake suggested on the label.
10 WATER QUALITY:Hard water
11 COMPATIBILITY:Trace elements.
12 EQUIPMENT:Boom sprays:
Carrier volume: 20-1000 L water/ha (50-150 L/ha on label). Higher volumes up to run-off can be used in dense canopies.
Nozzles: Flat fan. Producing a droplet size of 200-300 microns VMD.
Pressure: 150-400 kPa.
Aerial:Boom or Micronair delivering 20-30 L/ha with 200-250 micron VMD droplets.
13 SPRAYER DECONTAMINATION:Clean Up:
Remove filters and clean separately. Triple rinse with water or water plus 0.25% wetting agent and run through boom.
Decontamination: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.
Chlorine based cleaners are NOT recommended.
14 HERBICIDE RESISTANCE:Add extra Dim herbicide if Annual Ryegrass is Fop tolerant and Dim susceptible.
15 REPLANTING INTERVALS:
Motsa lasts longer in light red soils.
16 WITHHOLDING PERIODS:
|Beans; Faba||Harvest||Not required|
|Peas; Field||Harvest||Not required|
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:No particular effect.
20 MODE OF ACTION:Inhibitor of fat synthesis. Inhibits acetyl Coenzyme A carboxylase.
Uptake and translocation:Mainly leaf absorbed with some root absorption. Translocated.
Physiological effects:Residual Life and Breakdown:
Motsa lasts longer in light red soils and may cause effects up to 12 weeks after spraying.
21 SELECTIVITY:Most broadleaf plants have good tolerance. Most grasses apart from Vulpia species (Silver Grass) are sensitive. High rates are required for perennial grasses.
Crop tolerance:Good crop tolerance.
Varietal sensitivities:Effect on Clover Species:
Effect on Medic Species:No effect.
Effect on Lucerne:No effect.
Effect on Native Plants:Little or no effect on most broad-leaved species. Test before use on native grasses.
22 DISEASE AND INSECT EFFECTS:23 PLANT SYMPTOMS:
Grasses show reddening and yellowing in 5-10 days followed by death.
SECONDARY EFFECTS:24 TOXICITY:
Harmful if swallowed. Harmful if inhaled. Will irritate eyes and skin.
Details:Poison schedule - S
Mammalian toxicity -
Acute oral LD50 - 3610 mg/kg (male rats) and 2920 mg/kg (female rats) for clethodim. >2000 mg/kg (rats) for haloxyfop. [For comparison table salt is 3000 mg/kg]
Acute dermal LD50 - >5000 mg/kg (rabbit) for clethodim. >2000 mg/kg (rabbit) for haloxyfop.
Skin - Prolonged contact with the concentrate may cause dryness and flaking of the skin. The spray mix is not expected to be irritating.
Eye - Clethodim is a moderate eye irritant and concentrate in the eyes may caused vision impairment for weeks if eyes are not rinsed immediately. Haloxyfop may cause severe eye irritation and possible corneal damage.
Vapour inhalation - LC50 - 5.4 mg/L air (4 hour rat) for clethodim. 4.7 mg/L air (4 hour rat) for haloxyfop. Solvent inhalation may cause chemical pneumonia. Inhalation of spray mist under normal conditions is not expected to cause health effects.
Chronic oral toxicity NOEL - ppm for two years. High doses of clethodim has caused increase liver weight and anaemia in laboratory animals. Repeated high oral doses of haloxyfop has caused liver toxicity in rats and mice.
Not mutagenic or teratogenic (i.e. does not cause cancer or reproductive problems).
Acceptable Daily Intake (ADI) -
Other Species - Birds - toxicity.
Fish - toxic. LC50 > ppm.
Invertebrates - toxicity.
Bees - toxicity.
25 TOXICITY SYMPTOMS:Hypersensitivity, muscle fibrillation, tremor, uncoordinated gait, rapid or irregular respiration, excess salivation and urinary incontinence.
26 FIRST AID:If SWALLOWED - Do NOT induce vomiting.
If in EYES - Irrigate with plenty of water immediately. See and eye specialist.
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. No antidote.
27 ENVIRONMENTAL FATE:Half life in soil: May last for 12 weeks in light red soils.
Half life in water: days at pH5 and 35 C.
It has an EPA classification for soil mobility that ranges from
Ground water contamination
Accumulation in milk and tissues.
Hydrolysis half life:
