    Crop Other Names What You'll See in the Field
    Cabbage — Diamondback moth हीरक पृष्ठ पतंगा (Heerak Prishth Patanga), डायमंड बैक मॉथ Small, pale green larvae that wriggle backwards and drop on a silk thread when disturbed. They scrape the underside of leaves, leaving papery "windows" that later become holes; in heavy attack the leaves are riddled with holes and the developing head is damaged and fouled with droppings.
    Cabbage — Aphids माहू / चेपा (Mahu / Chepa) Colonies of small, soft-bodied green, yellow or black insects on tender shoots and the underside of leaves; leaves curl and crinkle, growth is stunted, and sticky honeydew on the leaves turns black with sooty mould.
    Okra (Bhindi) / Cotton — Aphids, Jassids, Thrips, Whitefly माहू / चेपा, हरा तेला (Hara Tela), थ्रिप्स, सफेद मक्खी (Safed Makkhi) Aphids: colonies of small, soft-bodied green, yellow or black insects on tender shoots and the underside of leaves; leaves curl and crinkle, growth is stunted, and sticky honeydew on the leaves turns black with sooty mould. Jassids: small, wedge-shaped green insects that move sideways quickly on the underside of leaves; leaf edges turn yellow, then reddish-brown, and curl downwards ("hopper burn"), and the plant looks stunted. Thrips: tiny, slender, straw-coloured insects hidden in leaf folds, buds and flowers; leaves show silvery streaks or patches, curl upwards and become crinkled and brittle. Whitefly: tiny white-winged insects fly up when the plants are shaken; they and their nymphs suck sap from the underside of leaves, causing yellowing and curling. Sticky honeydew on the leaves turns black with sooty mould.
    Cumin — Aphids, Thrips माहू / चेपा (Mahu / Chepa), थ्रिप्स Aphids: colonies of small greenish insects on tender shoots, flower umbels and developing seeds; plants turn sticky and dull, and seed setting is poor. Thrips: tiny, slender, straw-coloured insects hidden in leaf folds, buds and flowers; leaves show silvery streaks or patches, curl upwards and become crinkled and brittle.
    Chilli — Aphids, Thrips माहू / चेपा, थ्रिप्स Aphids: colonies of small, soft-bodied green, yellow or black insects on tender shoots and the underside of leaves; leaves curl and crinkle, growth is stunted, and sticky honeydew on the leaves turns black with sooty mould. Thrips: tiny, slender, straw-coloured insects hidden in leaf folds, buds and flowers; leaves show silvery streaks or patches, curl upwards and become crinkled and brittle.
    Mango — Hoppers, Thrips आम का फुदका / भुनगा (Bhunga), थ्रिप्स Hoppers: wedge-shaped insects that jump and fly off the flower panicles with a clicking sound when disturbed; they suck sap from the panicles, so flowers dry and drop and little fruit sets, and honeydew turns the leaves black with sooty mould. Thrips: silvery or brownish scraping marks on tender leaves, panicles and young fruit skin.
    Onion — Thrips थ्रिप्स (Thrips) Silvery-white streaks and blotches on the leaves; in heavy attack the leaf tips twist, turn brown and dry, and bulbs remain small.
    Pomegranate — Thrips थ्रिप्स (Thrips) Brownish scabby scars and rough, russeted patches on the fruit skin, especially around the calyx end; tender leaves become curled and distorted.

    Mode of Action

    Tolfenpyrad is a pyrazole-carboxamide insecticide (IRAC Group 21A — mitochondrial complex I electron transport inhibitors, METI). It blocks the first step of the energy-producing respiratory chain in the insect's mitochondria, so the cells can no longer produce energy (ATP); the pest stops feeding, becomes inactive and dies. It acts mainly by contact, with some stomach action, against nymphs, larvae and adults of the listed pests.

    Features & Benefits

    • A single active registered against both sucking pests (aphids, jassids, thrips, whitefly, hoppers) and a leaf-eating caterpillar (diamondback moth in cabbage).
    • Registered across vegetables, cotton, cumin, onion and fruit crops (mango, pomegranate).
    • Group 21A mode of action differs from neonicotinoids, organophosphates, pyrethroids and diamides — useful in rotation for resistance management.
    • EC formulation mixes readily in water to form a uniform spray emulsion.

    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.

    Crop Target Pest Dose per Acre Water Volume per Acre Waiting Period (PHI)
    Cabbage Diamondback moth, Aphids ~400 ml ~200 litres 5 days
    Okra (Bhindi) Aphids, Jassids, Thrips, Whitefly ~400 ml ~200 litres 3 days
    Cotton Aphids, Jassids, Thrips, Whitefly ~400 ml ~200 litres 26 days

    Figures above are converted from the CIB&RC-registered per-hectare rate (1 ha ≈ 2.47 acres): 150 g a.i./ha, 1000 ml formulation/ha, 500 L water/ha for all listed crops; waiting periods are crop-wise as listed by CIB&RC. 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 and waiting period for your crop from the table.
    2. Fill the spray tank half-way with water, add the measured quantity of the product, stir well, and top up to the full volume while stirring.
    3. Spray uniformly so that both surfaces of the leaves, the growing tips and (in mango) the flower panicles are well covered, since the product acts mainly by contact.
    4. Spray when the pest first appears or crosses 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.
    • Follow the recommended dose strictly; do not mix with other pesticides unless specifically recommended.
    • Respect the crop-wise waiting period (PHI) in the table before harvesting the treated crop — 3 days for okra, 5 days for cabbage, 7 days for chilli, mango and pomegranate, 10 days for onion, 26 days for cotton and 29 days for cumin.
    • Do not spray on flowering crops while bees are actively foraging; spray in the early morning or late evening instead.
    • 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.
