Which Problem Is This For? (Symptom Guide)

Mode of Action

Fenpropathrin is a synthetic pyrethroid (IRAC Group 3A, sodium channel modulator). It keeps the sodium channels in the insect's nerve cells open, so the nerves fire continuously; the pest is quickly knocked down, becomes paralysed and dies. It acts by contact and stomach action and, unlike many pyrethroids, also has activity against mites, which is why it is registered for both insect pests and mites. It also has a repellent effect on some pests.

Features & Benefits

• Covers chewing pests (bollworms, shoot and fruit borers, stem borer, leaf folder), sucking pests (whitefly, thrips) and mites under one registration.
• Quick knock-down action by contact and stomach action.
• Registered on cotton, chilli, brinjal, okra, tea and paddy.
• Emulsifiable concentrate (EC) formulation that mixes readily with water.

Recommended Usage of Fenpropathrin 30% EC Insecticide

The table below gives the recommended dose, water volume and waiting period per acre, 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): cotton, chilli, brinjal and okra — 75–100 g a.i./ha, 250–340 ml formulation/ha, 750–1000 L water/ha (waiting period 14, 7, 10 and 7 days respectively); tea — 50–60 g a.i./ha, 165–200 ml/ha, 400–500 L/ha, 7 days; paddy — 100 g a.i./ha, 333 ml/ha, 500 L/ha, 30 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 dose from the table.
2. Mix the measured quantity in a little water first, then add it to the spray tank and top up to the full volume while stirring.
3. Spray uniformly over the crop, covering shoots, flowers, fruits/bolls and both surfaces of the leaves.
4. Spray at the first sign of pest damage or at the crop stage advised by your local agricultural extension office; avoid repeated back-to-back pyrethroid sprays.
5. Spray in calm weather in the early morning or late evening, and avoid spraying if rain is expected within a few hours.

Precautions & Safety

• Wear appropriate PPE — mask/respirator, gloves, goggles and full-sleeved clothing — while mixing and spraying, and avoid inhaling the spray mist.
• Follow the recommended dose strictly; do not mix with other pesticides unless specifically recommended.
• Respect the waiting period (PHI) before harvesting the treated crop — 7 days for chilli, okra and tea, 10 days for brinjal, 14 days for cotton and 30 days for paddy.
• Pyrethroids are highly toxic to fish and bees: do not let spray wash or field water reach ponds, fish tanks, streams or drinking-water sources.
• Do not spray on flowering crops while bees are actively foraging; spray in the early morning or late evening instead.
• 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 spraying, and change out of contaminated clothing before eating, drinking or smoking.
