An agricultural insecticide that controls a wide range of insects at low rates. It is usually formulated as an off white liquid suspension concentrate with a slightly sweet odour. There are concentrated 500 g/L formulations used as seed dressings, 200 g/L formualtions for boom spraying and low concentration (3 and 8.5 g/L formulations) designed for ultra low volume or aerial applications
9. APPLICATION METHODS AND TIPS:
For ground spray applications, aim for 60 drops/cm2. If droplet size >250um then use >40 L/ha application volume. Don't use rotary atomisers for aerial spraying. Don't spray where bees are foraging.
10. ADJUVANTS, WETTERS, OILS:
Generally not required but non ionic wetters are used for some applications such as Brassicas and Sugarcane.
11. EQUIPMENT:
Ensure a droplet density of 60 droplets/cm2 or more.
Droplet size of 100-250 microns VMD is preferred.
Flat fan nozzles for booms. Hollow cones for directed applications in sugarcane.
Aerial - Don't use rotary atomisers.
12. SPRAYER WASH OUT AND DECONTAMINATION:
13. WATER OR CARRIER DATA:
33-75 L water/ha for ground sprayers.
250 L water/ha for hi volume directed sprayers.
20-50 L water/ha for aerial spraying.
Ensure a droplet density of 60 droplets/cm2 or more

Acute dermal LD50 - 354 to >4000 mg/kg (rabbit).
Skin - Mild irritant. Not harmful. Not a sensitiser.
Eye - Severe irritant and may cause damage if not washed out immediately.
Vapour inhalation - LC50 - 0.682-1.07 mg/L air (rat). May cause headache, nausea, dizziness and weakness.

NOEL - 0.02mg/kg/d.
23. TOXICITY SYMPTOMS:
Respiratory difficulty, decreased reflexes, lethargy, tremors. Convulsions in severe cases.
24. FIRST AID:
If Swallowed - Rinse mouth with water. Induce vomiting if large amounts (more than a tablespoon of product) consumed. Don't allow vomit to be inhaled. Don't give anything by mouth to unconscious or semi conscious patient. If small amount swallowed then do NOT induce vomiting. Seek medical advice. Harmful. May cause headache, nausea, dizziness, weakness and convulsions
If in Eyes - Irrigate with water. Risk of serious damage to eyes. Seek medical advice immediately.
If on Skin - Wash with soap and water.
If Inhaled - Harmful - Remove victim to fresh air. Seek medical advice if symptoms develop. May cause headache, nausea, dizziness and weakness.
If patient has symptoms or is concerned contact a doctor immediately.
Advice to Doctor - Fipronil is a reversible GABA receptor inhibitor. It will induce neurological stimulation with possible convulsions. Treat Symptoms. No specific antidote. Due to slow gut absorption, symptoms may be delayed several hours to a day. Gastric lavage, saline purgative or activated charcoal may reduce gut absorption. Fipronil is slowly eliminated so continue monitoring. Phenobarbital and to a lesser extent benzodiazapines have been shown experimentally to prevent fipronil induced convulsions.
25. PROTECTIVE CLOTHING:
Safety goggles and face shield.
Elbow length PVC gl;oves.
Cotton overalls and washable hat.
Boots.
