6 min readFipronil 5% SC is a broad-spectrum systemic insecticide for stem borer, hoppers, thrips, aphids and whitefly in paddy, cabbage, chilli, sugarcane and cotton. It is toxic to bees and fish.
What is fipronil 5% SC?
Fipronil is a phenylpyrazole insecticide. "5% SC" means 5% active ingredient as a liquid suspension concentrate. It acts by contact and by stomach action, and it also moves a little inside the plant. Its group is different from organophosphates, pyrethroids and neonicotinoids, so it is useful when those start to fail.
Katyayani's Fantasy Fipronil 5% SC is listed for paddy, cabbage, chilli, sugarcane, cotton and other horticulture crops.
How does fipronil work?
Fipronil blocks the GABA-controlled chloride channels in the insect's nervous system. The insect cannot calm its nerves, goes into over-excitement, and dies. It is not a knockdown: insects can take one to three days to die, so do not re-spray the next morning.
Which pests does fipronil 5% SC control?
| Pest | Crops |
|---|---|
| Stem borer, brown plant hopper, green leafhopper | Paddy |
| Diamondback moth, cutworm | Cabbage, cauliflower |
| Thrips, aphids, jassids, whitefly | Chilli, cotton, vegetables |
| Borers and maggots | Sugarcane and other horticulture crops |
The crops above match the Katyayani Fantasy listing and other Indian 5% SC listings.
What is the fipronil 5% SC dosage?
Dose differs by brand and crop, and there is no single official table for all crops. Popular farm guides give the figures below, which you should treat as a starting point only:
| Crop | Reported dose | Note |
|---|---|---|
| Paddy (stem borer, BPH) | 400-500 mL per acre in 150-200 L water | Farm guide; confirm on label |
| Cabbage / cauliflower (DBM) | 300-400 mL per acre | Farm guide; confirm on label |
| General foliar | 2-4 mL per litre | Farm guide; confirm on label |
Use the dose printed on your own pack. Different 5% products can have different registered doses.
Can fipronil 5% SC be used for termite control?
Be careful here. Some websites sell 5% SC for termites, but Indian 5% SC crop-protection labels list borers, hoppers, thrips and similar pests, not termites. Termite treatment of buildings uses separate termiticide products with their own label rate. For termites in crops such as sugarcane, ask your agriculture officer which fipronil product is registered for that use before buying.
How to use fipronil safely?
- Highly toxic to fish and aquatic life. Never spray near ponds, canals or rice fields with fish.
- Toxic to bees. Do not spray on flowering crops when bees are active.
- Wear gloves, mask and full-sleeve clothes. Wash after spraying.
- Do not re-spray within 48 hours because the kill is slow by nature.
- Do not wash sprayer or empty pack into water bodies.
What to rotate with fipronil?
Rotate with a different insecticide group between sprays. Options in the Katyayani range include Thioxam Thiamethoxam 25% WG for sucking pests and Emathio Emamectin + Thiamethoxam WG for borers. Distributors can read more in agri-input franchise in India.
Conclusion
Fipronil 5% SC is a strong, different-group insecticide for borers, hoppers and sucking pests when used with care. Follow your pack, keep it away from bees and water, do not assume it is meant for termites, and rotate groups to keep it effective.
