8. GENERAL DESCRIPTION:

A contact or ingested broad spectrum insecticide and spider killer with a short residual life of 1 day to 3 weeks.

9. APPLICATION METHODS AND TIPS:

Ensure complete even coverage.

Add a wetting agent when treating hard to wet or waxy plants.

Avoid spraying flowering crops if possible to reduce bee losses.

Best results when applied under fine calm conditions.

Results with misters, ULV misters and application with diesel have generally been poorer than those achieved by application with a boom spray.

Poor results often occur if there is less than 50% plant cover over the ground.

Not compatible with alkaline sprays such as Bordeaux mixture or lime.

Rainfast in 3 hours for emulsifiable concentrate and 6 hours for the wettable powder formulations.

10. ADJUVANTS, WETTERS, OILS:

Non ionic wetting agents may give better cpverage when used as a seed dressing.

11. EQUIPMENT:

Hydraulic nozzles for booms.

Rotary atomizer for aerial application.

12. SPRAYER WASH OUT AND DECONTAMINATION:

13. WATER OR CARRIER DATA:

Don't use with alkaline water as it undergoes alkaline hydrolysis resulting in decreased half life in the tank.

14. WEATHER:

15. RAINFASTNESS:

1 hour

16. SOIL:

17. PLANT HEALTH and OTHER EFFECTS:

May injure some varieties of apricots, beans, chrysanthemums, cotton, figs, lemons, olives, peaches, tomatoes, walnuts, hops, pines.

May russet some apple varieties and ornamentals.

Seedling citrus and greenhouse ornamentals may be injured.

Use formulations made specially for fruit trees and citrus when applying to these crops.

19. PLANT BACK PERIODS or RECROPPING INTERVALS:

20. MODE OF ACTION:

Active by contact and ingestion for insects. Rapidly absorbed and distributed within the plant to kill sucking and chewing insects. Plants break it down relatively quickly which reduces its residual life. Acts on the insects nervous system.

A group 1B, organphosphate, acetylcholine esterase inhibitor.

21. PESTICIDE RESISTANCE:

Some spotted alfalfa aphids and mite populations are resistant.

22. TOXICITY:

Poison schedule - S6

Mammalian toxicity - Highly toxic.

Acute oral LD50 - 200-300 mg/kg

Acute dermal LD50 - 700-1150 mg/kg

Vapour inhalation - LD50 mg/L

Skin - Irritant.

Eye - Irritant.

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 - 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 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.
