A non systemic, contact or ingested broad spectrum insecticide with a moderate residual life.
9. APPLICATION METHODS AND TIPS:
Thorough coverage in essential. Don't spray areas where bees are foraging. Safer to handle than parathion.
Compatible with most other pesticides. Apply immediately if used with alkaline solutions such as Bordeaux mixture or lime sprays.
Use on golf courses and pastures may cause death of foraging birds.
Applied by boom sprays, high volume sprayers, air assisted misters, aircraft and directly to grain a grain protectant.
Buffer zones for sensitive areas including aquatic areas, dwellings and neighbours range from 300 m upwind for aerial spraying to 50 m for low rate boom spraying.
Pasture minimum re-application intervals are 7 days or 14 days if stock are being oversprayed.
Crop minimum re-application intervals are usually 14 days.
10. ADJUVANTS, WETTERS, OILS:
Generally not required.
11. EQUIPMENT:
12. SPRAYER WASH OUT AND DECONTAMINATION:
Triple rinse with water and wetting agent.
13. WATER OR CARRIER DATA:
Apply immediately if used with alkaline water because it breaks down quickly in alkaline conditions.

17. PLANT HEALTH and OTHER EFFECTS:
May russet some apple varieties. Some cotton, Brassica, canola and fruit crops have been damaged at high rates.
May discolour sorghum and cause leaf spotting. Pioneer 845, Alpha strains and Golden Acres sorghum varieties may be serverely damaged especially at late growth stages.

22. TOXICITY:
Poison schedule - S6
Mammalian toxicity - Moderate toxicity.
Acute oral LD50 - 250-673 mg/kg
Acute dermal LD50 - 1500-3000 mg/kg
Vapour inhalation - LD50 mg/L
Skin - Mildly irritating.
Eye - Mildly irritating
Main exposure routes - Handling concentrate. Air blast application.
Birds - Extremely toxic. LD50 is mg/kg.
Fish - Extremely toxic. LC50 is ppm.
Invertebrates - Extremely toxic. LC50 is
Bees - Highly toxic.
Summary:
Details:
Poison schedule - S6
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 fatigue during exposure or several hours later. Dizziness, vomiting, stomach pains, contracted pupils, muscle weakness, twitching, tremor, slow heart beat, blurred vision and sweating may occur with higher exposure levels.
Continual low level exposure may cause influenza like symptoms.
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.
