A contact and short residual insecticide for some sucking and chewing insects. Highly toxic to bees and may kill hives. Also used for thinning apples. An anticholinesterase compound.
9. APPLICATION METHODS AND TIPS:
Areas where bees are foraging should not be sprayed.
Thorough spray coverage is essential.
Not compatible with alkaline solutions such as Bordeaux mixture and lime sulphur.

17. PLANT HEALTH and OTHER EFFECTS:
Some fruit varieties are sensitive especially apples and pears. Watermelon and Ivy have been injured. Thins apples if applied within 28 days of petal fall. High doses reduce the germination of grasses. May injure tender foliage under wet or humid conditions.

22. TOXICITY:
Poison schedule - S
Mammalian toxicity - Moderately to low toxicity.
Acute oral LD50 - 255-400 mg/kg
Acute dermal LD50 - 500->2000 mg/kg
Skin - Not irritating.
Eye - Mildly irritating
Main exposure routes - Handling concentrate. Air blast application.
Birds - Very low toxicity. LD50 is > 2000 mg/kg.
Fish - Low to moderate toxicity.
Invertebrates - extremely toxic.
Bees - extremely toxic may kill hives.
Summary:
Details:
Poison schedule - S
Mammalian toxicity -
Acute oral LD50 - mg/kg (rats), [For comparison table salt is 3000 mg/kg]
Acute dermal LD50 - > mg/kg (rabbit).
Skin -
Eye -
Vapour inhalation - LC50 - > mg/L air (rat).
Chronic oral toxicity NOEL - ppm for two years.
Not mutagenic or teratogenic (i.e. does not cause cancer or reproductive problems).
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.
24. FIRST AID:
Contact a doctor or poison information centre on 008 119 244.
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. Medical attention must be sought after taking atropine.
Remove contaminated clothing and wash skin.
If breathing has stopped apply resuscitation
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.
