Which Problem Is This For? (Symptom Guide)

Not sure whether the damage in your field matches this insecticide's use case? This guide helps match what you see in the field to this insecticide's approved crop-wise uses.

Mode of Action

Fipronil belongs to the phenylpyrazole group (IRAC Group 2B). It blocks the GABA-gated chloride channels in the insect's nervous system, which stops the normal calming signals between nerve cells. The insect's nerves become over-excited, leading to paralysis and death. Applied as granules into standing water or the soil, the active ingredient is taken up by the roots and moves into the plant (systemic action), and also acts on soil insects such as termites and root borers that come in contact with the treated soil.

Features & Benefits

• Ready-to-use granules — broadcast or apply in the soil; no spray tank or mixing needed.
• Broad registered use across paddy, sugarcane and wheat, covering borers, hoppers, gall midge, whorl maggot and termites.
• Systemic action through the roots, plus soil activity against termites and root borers.
• Phenylpyrazole mode of action (Group 2B) is a useful rotation partner with other insecticide groups for resistance management.

Recommended Usage of Fipronil 0.3% GR Insecticide

The table below gives the recommended granule quantity per acre for each crop, converted from the CIB&RC-registered per-hectare rate — see the note below the table for conversion details. Always confirm against the current product label before use.

Figures above are converted from the CIB&RC-registered per-hectare rates (1 ha ≈ 2.47 acres): Paddy — 50–75 g a.i./ha, 16.67–25 kg formulation/ha, PHI 32 days; Sugarcane — 75–100 g a.i./ha, 25–33.3 kg formulation/ha, PHI 9 days; Wheat (termites) — 0.06 kg a.i./ha, 20 kg formulation/ha, PHI 91 days. Always confirm the current dose on your specific product's label before use.

How to Use

1. Identify the pest from the symptom guide above and confirm the correct quantity for your crop from the table.
2. Weigh out the required quantity of granules for your field area; mixing them with a little dry sand helps spread them evenly.
3. For paddy, keep 3–5 cm of standing water in the field, broadcast the granules evenly, and avoid draining the water for 3–4 days after application.
4. For sugarcane, apply the granules in the furrows or near the root zone and cover with soil, followed by irrigation if the soil is dry.
5. For wheat termite control, apply the granules into the soil (at sowing or before irrigation) so they are mixed into the root zone.
6. Wear gloves while handling and broadcasting the granules.

Precautions & Safety

• Wear gloves, a mask and full-sleeved clothing while handling the granules, and avoid inhaling the dust.
• Fipronil is highly toxic to fish and to bees — do not let water from treated fields flow into ponds, fish tanks, streams or drinking-water sources.
• Respect the waiting period (PHI) for each crop given in the table above before harvest.
• Follow the recommended dose strictly; do not apply more than the label rate.
• Store in the original, tightly closed container in a cool, dry place away from direct sunlight, food and feed, and out of reach of children and livestock.
• Wash hands, face and any exposed skin thoroughly with soap and water after handling, and change out of contaminated clothing before eating, drinking or smoking.
