6 GENERAL DESCRIPTION:A post emergence, contact herbicide for the control of Barnyard Grass in Rice.
7 APPLICATION METHODS AND TIPS:Do not apply within 14 days of insecticides or serious damage to Rice crops may occur. Carbaryl and organophosphates have caused the most damage.
Avoid applying other pesticides or liquid fertilisers within 14 days of application of propanil unless it has been locally proven as safe.
Best results on young actively growing weeds. Ensure thorough coverage as this is a contact herbicide.
Avoid spraying stressed Rice crops.
Flood rice then thoroughly drain before application then flood 1-5 days after application.

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.

22 DISEASE AND INSECT EFFECTS:
23 PLANT SYMPTOMS:
Harmful if swallowed, inhaled or absorbed through skin. Irritating to eyes.
Details:Poison schedule: S5
Mammalian toxicity: Low to moderate.
Acute oral LD50(rat): 1420-1580 mg/kg (males) and 960-1090 mg/kg (females). [For comparison table salt is 3000 mg/kg]. Low toxicity if swallowed.
Acute dermal LD50: >5000 mg/kg (rabbit).
Skin: Brief contact may cause moderate skin irritation with local redness. May cause drying and flaking of the skin. Prolonged skin contact is unlikely to result in absorption of harmful amounts. The LD50 for skin absorption in rabbits is >5000 mg/kg.
Eye: May cause severe eye irritation with corneal injury. Vapour may cause eye irritation experienced as mild discomfort and redness.
Vapour inhalation: LC50 > mg/L air (rat).
Excessive exposure may cause irritation to upper respiratory tract (nose and throat) and lungs.
Chronic oral toxicity: NOEL mg/kg for two years.
Not mutagenic or teratogenic in animal studies (i.e. does not cause reproductive problems in animal tests).
Carcinogenicity: Propanil has caused cancer in laboratory animals. Isophorone has caused cancer in some laboratory animals. For methyl isobutyl ketone, kidney effects and/or tumours have been observed in male rats. These effects are believed to be species specific and unlikely to occur in humans.
Systemic and other target organ effects: Excessive exposure to propanil may cause methemoglobinemia, thereby impairing the blood's ability to transport oxygen. Excessive exposure may cause haemolysis, thereby impairing the blood's ability to transport oxygen. In animals, effects have been reported on the following organs: blood, liver, and male reproductive organs. Excessive exposure to methyl isobutyl ketone may cause respiratory irritation, gastrointestinal distress, anaesthesia, and kidney and liver effects.
NOEL: 20 mg/kg/day.
Acceptable Daily Intake (ADI): 0.2 mg/kg/day.
Other Species:Toxic to fish.
Birds: Moderate toxicity on acute basis and slightly toxic on a dietary basis. LD50 is between 51 and 500 mg/kg. LC50 is between 1001 and 5000 mg/kg.
Fish: High toxicity LC50 > 170 mg/L (Rainbow Trout). LC50(96 hour) < 3.7 mg/L (Bluegill). LC50 for sensitive species = 0.1-1 mg/L.
25 TOXICITY SYMPTOMS:May cause severe eye irritation with corneal injury.
Vapour may cause eye or throat irritation, experienced as mild discomfort and redness.
Excessive exposure by inhalation may cause irritation to upper respiratory tract (nose and throat) and lungs.
Symptoms of excessive exposure may be anaesthetic or narcotic effects; dizziness and drowsiness may be observed.
26 FIRST AID:If SWALLOWED: Do NOT induce vomiting. Give a glass of water to sip. Do NOT give anything by mouth to a semiconscious or unconscious patient.
If in EYES: Irrigate with plenty of water for 5 minutes, remove contact lenses if present and irrigate eyes for another 10 minutes. Obtain medical attention without delay as corneal injury may occur.
If on SKIN: Rinse with plenty of water, remove contaminated clothing, wash with soap and water. Call a doctor if irritation occurs.
If INHALED: Remove patient to fresh air. Supply oxygen if breathing is difficult. If effects occur see a doctor.
Advice to doctor: If lavage is performed, suggest endotracheal and/or oesophageal control. Danger from lung aspiration must be weighed against toxicity when considering emptying the stomach. Maintain adequate ventilation and oxygenation of the patient. Administer 100% oxygen to relieve headache and a general sense of weakness. Determine methemoglobin concentration of blood every 3 to 6 hours for first 24 hours. It should return to normal within 24 hours. The treatment of toxic methemoglobinemia may include the intravenous administration of methylene blue.
Persons receiving significant exposure should be observed 24-48 hours for signs of respiratory distress.
