8. GENERAL DESCRIPTION:
A contact or ingested broad spectrum insecticide and spider killer with a short residual life and relatively low toxicity to the operator.
9. APPLICATION METHODS AND TIPS:
Heavy infestations often require repeat treatments.
Thorough coverage is necessary for best results.
ULV form may damage paint on vehicles.
Reacts with iron and other heavy metals.
Compatible with most other pesticides. Do not mix with alkaline sprays such as Bordeaux mixture or lime. Alkaline solutions reduce residual activity rather than affecting the initial kill.
Applied as a high or low volume broadcast spray.

22. TOXICITY:
Poison schedule - S6
Mammalian toxicity - Moderately toxic.
Acute oral LD50 - 1400-1900 mg/kg
Acute dermal LD50 - >4000 mg/kg
Vapour inhalation - LD50 mg/L
Skin - Irritant.
Eye - Irritant.
Main exposure routes - Handling concentrate. Air blast application.

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.

Half life in water - 11 days.
It has an EPA classification for soil mobility that ranges from
Ground water contamination. Low likelihood of leaching. High liklehood of surface runoff.
Accumulation in milk and tissues.
pH stability - Relatively stable in neutral aqueous media.
Photolysis rate - 16 hours in river water. 6 weeks in distilled water.
Hydrolysis half life (days) - 6 at ph7. 107 at pH5. 0.49 at pH9.

29. COMPATIBILITY:
See HerbiGuide for compatability with other herbicides, insecticides and fungicides.
See HerbiGuide for a full list of pesticide compatibilities.
Compatible with most other pesticides, white oil, summer spray oil, spray oils, protein hydrolysate.
Do not mix with alkaline sprays such as Bordeaux mixture or lime. Alkaline solutions reduce residual activity rather than affecting the initial kill.
