How 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.

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