19. PLANT BACK PERIODS or RECROPPING INTERVALS:

20. MODE OF ACTION:

A stomach and contact poison for insects and spiders. Acts on the insects nervous system.

Moluscicide.
Cholinesterase inhibitor.

21. PESTICIDE RESISTANCE:

Some species may be resistant or develop resistance with continued application. Rotate with products from alternative groups.

22. TOXICITY:

Poison schedule - S7
Summary: Highly toxic cholinesterase inhibitor.
Details: High toxicity. Repeated exposure may cause allergic reactions. Repeated minor exposures may have a cumulative poisoning effect.
Poison schedule - S7
Mammalian toxicity - Highly toxic.
Acute oral LD50 - 4.4 - 13 mg/kg. Highly toxic.
Acute dermal LD50 - 200-280 mg/kg.
Skin - Harmful in contact with skin. May cause sensitisation. Absorbtion through the skin may be a significant source of exposure. Not irritating.
Eye - Irritant
Vapour inhalation - LC50 - 0.15 mg/L air (rat). Very toxic if inhaled.
Chronic oral toxicity NOEL - ppm for two years.
Not teratogenic (i.e. does not reproductive problems).
Some in vitro mutagenicity has been recorded but none in vivo. Not classed as a carcinogen.
Acceptable Daily Intake (ADI) -

23. TOXICITY SYMPTOMS:

Initial symptoms include headache, nausea, lack of appetite and lassitude during exposure or several hours later. Dizziness, vomiting, stomach pains, contracted pupils, blurred vision and sweating may occur with higher exposure levels. Respiratory paralysis and cyanosis (blueness of the skin due to lack of oxygen) may occur at higher exposure levels. Onset of symptoms may be delayed. Cholinesterase inhibition may persist for several weeks.
Symtoms usually appear 1-3 hours after significant exposure.

24. FIRST AID:

Contact a doctor or poison information centre on 131126.
If SWALLOWED - Give atropine (0.6mg) tablets every quarter hour then every half hour until signs of flushed face, dilated pupils, dry mouth and fast pulse appear. Don't give atropine to cyanosed (blue) patients. Medical attention must be sought after taking atropine. Contact Poisons Information Centre urgently. Transport patient ot hospital quickly. Don't give anything by mouth to an unconscious person.
If in EYES - Irrigate for 15 minutes with plenty of water. See a doctor.
If on SKIN - Rinse with plenty of water, remove contaminated clothing, wash with soap and water. Contact Poisons information Centre.
If INHALED - Remove patient to fresh air. Contact Poisons Information Centre. If breathing has stopped apply resuscitation.
If patient has symptoms or is concerned contact a doctor immediately.
Poisoning usually occurs through skin absorption. Effects are cumulative and dangerous levels may develop before symptoms become noticeable. If you are exposed to organophosphate for more than 30 hours per month then levels of acetylcholinesterase enzyme should be regularly checked. If levels drop below 60% of normal then work with organophosphates should stop until levels improve. This may take several weeks.
Advice to doctor - Treat symptomatically. Antidote is Atropine sulphate. In severe cases pralidoxime may be administered as well, if given within 24 hours of exposure. Atropine should not be given to cyanosed patient. Monitor cardiac, respiratory and central nervous system function. Monitor red blood cell count and plasma chlinesterase levels. Administer oxygen if necessary. Watch for pulmonary oedema and delayed neurological symptoms.
Contraindications. Adrenergic derivatives. Never give patient morphine, theophylline or theophylline-ethylenediamine. Large amounts of intravaneous fluids are usually contraindicated because of the threat of pulmonary oedema.
