Product scienceHow Caldan 4G Works

Dhanuka describes Caldan as acting through contact, systemic and stomach-poison activity. At the mode-of-action level, Cartap Hydrochloride is an IRAC Group 14 channel blocker that affects nicotinic acetylcholine receptors in susceptible insects. Do not treat another Cartap or Group 14 brand as a different-mode rotation merely because its name or pack differs.

Caldan 4G is a field-applied granule. Do not convert these kilogram-per-area directions into ml-per-litre or spray-tank rates.

Useful detailsHow to Apply Responsibly
  1. Confirm the use: Match the paddy crop, target pest and application timing to the current label.
  2. Select the correct pest-specific rate: Stem borer and the leaf folder/whorl maggot row do not have identical upper rates.
  3. Measure by field area: Calibrate the granular applicator or other label-approved method to distribute the required kilograms evenly.
  4. Avoid concentrated piles: Apply uniformly and prevent granules from entering water outside the treated field.
  5. Do not infer mixing: No tank-mix or simultaneous-use recommendation is made on this page.
  6. Protect the applicator: Wear all PPE required by the current label while handling, applying and cleaning equipment.
Use with careSafety & Disclaimer

Read the current Dhanuka Caldan 4G label before opening the pack. Use only for a registered crop, pest, rate, timing and method; wear the specified PPE; avoid contact, inhalation and accidental ingestion; keep away from children, animals, food and feed; and prevent environmental contamination. If exposure is suspected, seek medical attention promptly and take the label or container. This product page is a verified buying guide, not a substitute for the statutory label or qualified agronomic advice.
