Fipronil 5% SC Insecticide Uses

Fipronil 5% SC is a broad-spectrum insecticide from the phenylpyrazole chemical class, registered for use in India under the Insecticides Act, 1968 and sold under various trade names including Agent SC and Kisan Fipro Plus. It carries label recommendations across cereals (rice), cash crops (cotton, sugarcane) and vegetables (cabbage, chilli), used as a foliar spray with systemic, contact and stomach action against borers, hoppers, thrips, aphids, whitefly and bollworms. Fipronil remains legally registered and sold in India; always confirm the current pack label before use. This page lists its mode of action, key benefits and the recommended crop-wise dosage as per manufacturer labels.

Mode of Action

Fipronil acts on the insect nervous system by blocking GABA-gated chloride channels, which normally act as an "off switch" that calms nerve activity. By blocking these channels, fipronil disrupts the insect's inhibitory nervous system, leading to uncontrolled nerve and muscle activity, hyperexcitation, paralysis and eventually death. It has systemic movement within the plant along with contact and stomach action, meaning it can control pests that feed on treated leaves (stomach action), pests that come into direct contact with the spray (contact action), and pests feeding on plant sap after the product is absorbed and translocated (systemic action). This combination of actions makes it effective against a wide range of pest types, including internal feeders like stem borers that are harder to reach with purely contact insecticides. Several fipronil-based products also report a phytotonic (plant vigour) benefit alongside pest control.

Features & Benefits

• Broad-spectrum control combining systemic, contact and stomach action — effective against internal feeders (stem borers), sucking pests (hoppers, aphids, thrips, whitefly) and bollworms in a single product.
• Effective at relatively low use rates due to its potent, targeted mode of action on the insect nervous system.
• Provides good residual control during continuous or repeated pest infestation.
• Reported phytotonic benefit — supporting plant vigour, height and flower/fruit development — alongside pest control.

Recommended Usage of Fipronil 5% SC Insecticide

The table below gives the commonly recommended dose and water volume per acre for each crop and target pest, as listed on manufacturer labels for this active ingredient. Always spray in the recommended water volume for uniform coverage, and confirm against the current product label before use.

Doses above are the commonly listed formulation-label rates for Fipronil 5% SC, rounded to practical spray-tank quantities. The long waiting period listed for sugarcane reflects that early shoot/root borer treatment is applied near planting, well ahead of harvest. Always confirm the current pack label/CIB registration and consult your local agricultural extension office for the latest guidance before harvest.

How to Use

1. Identify your crop and target pest from the table above, and confirm the correct dose per acre.
2. Measure the required quantity and pre-mix it in a small quantity of water, then add this to the spray tank and top up to the full water volume while stirring, so the suspension concentrate disperses evenly.
3. Spray using a knapsack or power sprayer fitted with a flat-fan or hollow-cone nozzle for uniform leaf coverage, preferably during the early morning or late evening.
4. Apply at the first sign of pest appearance; for stem borers and other internal feeders, timely application before larvae bore into plant tissue improves control.
5. Repeat sprays as advised by local agricultural extension based on pest pressure, and always respect the waiting period before harvest.

Precautions & Safety

• Wear appropriate PPE — mask/respirator, gloves, goggles and full-sleeved clothing — while mixing and spraying.
• Fipronil is highly toxic to bees and aquatic life; avoid spraying during crop flowering, avoid drift onto flowering weeds, and avoid contamination of ponds, streams or other water bodies.
• Do a small jar-compatibility test before tank-mixing with other agrochemicals.
• Store in the original, tightly closed container in a cool, dry place away from direct sunlight, food, feed and out of reach of children and livestock.
• Respect the waiting period (PHI) listed for each crop above before harvesting, and follow your local agricultural extension advice for the latest guidance.
• Avoid repeated, back-to-back applications on the same crop/pest and rotate with an insecticide from a different mode-of-action group as part of a resistance-management program.
• Wash hands, face and any exposed skin thoroughly with soap and water after handling or spraying, and change out of contaminated clothing before eating, drinking or smoking.
