Product details
Caldan 4G Insecticide | Cartap Hydrochloride 4% G
A granular rice insecticide for the listed pests. Keep the 4% granule separate from soluble cartap powders and granules with different strengths.
What it controls: Stem borer, leaf folder and whorl maggot in rice / paddy.
When to use it: At the crop and pest stage specified on the current Caldan 4G label.
What to include: The verified granule rate, field-placement method, water management and harvest restrictions.
Why Choose This Product? Key Benefits
- 🌾Rice-focused pest coverage: The manufacturer identifies three rice pests, so the intended crop scope is clear.
- 🛡️Contact and feeding exposure: The active ingredient can affect susceptible insects through contact and ingestion.
- 🌿Systemic activity: Plant uptake helps the active ingredient reach susceptible feeding pests.
- ⚖️Distinct granular form: The 4% G formulation is measured as granules. A rate from Cartap 50% SP or 75% SG is not interchangeable.
- 🔄A defined resistance group: Group 14 helps identify its mode of action. It is not a guarantee that a resistant local population will be controlled.

How It Works: Mode of Action
Cartap affects nerve transmission in susceptible insects. The product’s granular form determines how it must be handled, but does not by itself establish the approved placement procedure.
- The target insect is exposed: Contact, feeding and systemic uptake contribute to exposure under labelled conditions.
- Nerve channels are blocked: Cartap blocks channels associated with nicotinic acetylcholine receptors.
- Normal nerve messages are interrupted: The affected insect cannot function normally, leading to control of susceptible pests.
Use crop inspection and integrated pest management rather than assuming every insect life stage or every local resistant population will be controlled. Avoid repeated reliance on Group 14 without an appropriate plan.
Target Crops & Pests
These crop–pest uses are listed by Dhanuka. Confirm that the current label supplied with your pack includes the intended use.

These uses do not extend to other crops or targets. The supplied label must support the exact proposed use.
Dosage & Application Guide
No numerical Caldan 4G programme is supplied here. Confirm the rice granule rate, placement method, field-water conditions and harvest restrictions together before application.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (kg / Acre) | Water (L / Acre) | Dose (kg / Litre) | PHI (Days) |

Use the complete rice instructions supplied with this exact 4% granular formulation.
*The granule rate and harvest interval remain withheld. Missing information does not mean that water management or a waiting period is unnecessary.
A per-litre spray dose is not appropriate for this granular product. Do not dissolve it or use a soluble-cartap recipe unless the supplied label specifically directs that use.
How to Apply: Best Practices
- Confirm the rice pest: Identify stem borer, leaf folder or whorl maggot and check the supplied label before treatment.
- Use the exact formulation: Verify Cartap Hydrochloride 4% G on the container. Different cartap strengths and formulation letters require different instructions.
- Obtain placement and water directions: Confirm how granules must be distributed and what field-water conditions are required. A retailer’s irrigation schedule is not substituted here.
- Measure the treated area: Use the label’s product mass for the actual area, not a pack-size assumption.
- Avoid exposure and contamination: Wear label-specified protection and prevent granule dust, spills or runoff from reaching people, animals or water bodies.
- Record and inspect: Record the application and monitor the crop. Follow current label restrictions before repeats, re-entry or harvest.
Frequently Asked Questions
1. Is Caldan 4G the same as Caldan 50 SP?No. The active ingredient strength and formulation are different. Do not transfer quantities or preparation instructions between them.
2. Can I make a pump spray from Caldan 4G?No spray recipe is established for this granular product. Follow its specific label rather than the procedure for a soluble cartap formulation.
3. Can I use it in sugarcane?This draft retains the official rice/paddy scope only. A retailer’s additional sugarcane claim is not enough to establish that use for the current pack.
4. How long should water remain in the field?A current primary Caldan 4G water-management instruction was not verified. Follow the supplied label; no number of days is invented here.
5. Can it be mixed with fertilizers or other pesticides?No blanket mixture is recommended. A general compatibility claim does not establish a particular mixture, placement method or crop-safety outcome.
Safety & Disclaimer
Use only as permitted by the current Indian label supplied with the product. Wear the label-specified protective clothing and equipment; avoid skin and eye contact and breathing spray or dust. Do not eat, drink or smoke while handling pesticides. Wash exposed skin after work and change contaminated clothing.
Keep the original labelled container securely closed and away from children, animals, food, feed and drinking water. Prevent drift, spillage and equipment washings from reaching ponds, streams, wells or neighbouring crops. Do not reuse empty pesticide containers; follow the label and local disposal requirements.
For accidental exposure or suspected poisoning, stop work and obtain medical help promptly. Take the product label with you so the clinician can identify the formulation. Follow the label first-aid directions; do not invent a home treatment.
