Beta-cyfluthrin 8.49% + Imidacloprid 19.81% OD Insecticide Uses

Beta-cyfluthrin 8.49% + Imidacloprid 19.81% OD is a ready-mix combination insecticide registered for use in India under the Insecticides Act, 1968, formulated as an oil dispersion (OD) for foliar spraying. It combines beta-cyfluthrin, a synthetic pyrethroid, with imidacloprid, a neonicotinoid. It is registered against both sucking pests and chewing pests — aphids, jassids, whitefly and thrips, as well as shoot & fruit borer, girdle beetle, semilooper, tea mosquito bug and looper — in brinjal, soybean, cotton, chilli, cucumber, wheat, cashew and tea. This page lists its mode of action, key benefits and the recommended dosage as per the Central Insecticides Board & Registration Committee (CIB&RC) official list of approved insecticide uses (Government of India).

Mode of Action

This product combines two active ingredients with different modes of action. Beta-cyfluthrin is a synthetic pyrethroid (IRAC Group 3A) that keeps the sodium channels of insect nerve cells open, causing rapid knock-down, paralysis and death on contact or ingestion. Imidacloprid is a neonicotinoid (IRAC Group 4A) that binds to the nicotinic acetylcholine receptors in the insect's nervous system; it is systemic, moving into the plant and up through the sap, so sucking pests such as aphids, jassids and whitefly are controlled as they feed. Combining quick contact action with systemic action gives control of both chewing and sucking pests in one spray, and using two unrelated modes of action helps slow the development of resistance.

Features & Benefits

• Two active ingredients with different IRAC groups (3A and 4A) in one ready-mix formulation.
• Registered against both sucking pests (aphids, jassids, whitefly, thrips, tea mosquito bug) and chewing pests (shoot & fruit borer, girdle beetle, semilooper, looper).
• Beta-cyfluthrin gives fast contact knock-down; imidacloprid is taken up by the plant and protects against sucking pests feeding on the sap.
• Oil dispersion (OD) formulation for foliar spraying.
• Useful as a rotation option with insecticides from other IRAC groups for resistance management.

Recommended Usage of Beta-cyfluthrin 8.49% + Imidacloprid 19.81% OD 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): brinjal — 15.75 + 36.75 to 18 + 42 g a.i./ha, 175–200 ml formulation/ha; soybean — 31.5 + 73.5 g a.i./ha, 350 ml/ha; cotton — 18 + 42 g a.i./ha, 200 ml/ha; chilli — 27.9 + 65.1 g a.i./ha, 310 ml/ha; cucumber — 45 + 105 g a.i./ha, 500 ml/ha; wheat — 36 + 84 g a.i./ha, 400 ml/ha; cashew — 22.5 + 52.5 g a.i./ha, 250 ml/ha; tea — 27 + 63 g a.i./ha, 300 ml/ha; water 500 L/ha (cashew 500–1000 L/ha, tea 400 L/ha); waiting periods 5 days (chilli, cucumber), 7 days (brinjal, tea), 17 days (soybean), 21 days (cotton), 31 days (wheat) and 45 days (cashew). 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 for your crop from the table.
2. Shake the bottle well, measure the required quantity, mix it in a small quantity of water first, then add it to the spray tank and top up to the full volume while stirring.
3. Spray uniformly over the crop with a knapsack or power sprayer, covering the undersides of leaves where sucking pests sit, as well as the shoots, flowers and fruits or pods.
4. Spray when the pest first appears or reaches the level advised by your local agricultural extension office.
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 or getting it on the skin or in the eyes.
• Follow the recommended dose strictly; do not mix with other pesticides unless specifically recommended.
• Respect the crop-wise waiting period (PHI) before harvesting: 5 days for chilli and cucumber, 7 days for brinjal and tea, 17 days for soybean, 21 days for cotton, 31 days for wheat and 45 days for cashew.
• Imidacloprid is highly toxic to honey bees and beta-cyfluthrin is highly toxic to fish — do not spray on flowering crops while bees are actively foraging, and do not let spray wash or field water reach ponds, fish tanks, streams or drinking-water sources.
• 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.
