How It Works: Mode of Action
Cartap hydrochloride affects nerve signalling in susceptible insects. IRAC classifies it as a nicotinic acetylcholine receptor channel blocker (Group 14).
- Correct placement: The granules are applied directly in the labelled rice programme.
- Nerve disruption: Cartap blocks insect nerve-receptor channels, disrupting normal signalling.
- Pest response: Affected susceptible insects lose normal function, supporting control of the named rice pests.
Use within an appropriate local crop-management programme. Rotate modes of action where applicable; a different brand name alone does not mean a different mode of action.
Target Crops & Pests
The following crop and target information comes from the manufacturer’s product information. It is not an all-crop recommendation.

Keep each crop paired with its listed target. Follow the current product label if it is more restrictive, and do not extend this use to other crops, targets or methods.
Dosage & Application Guide
These quantities come from the exact Kritap-4G leaflet. Acre equivalents are calculated from the hectare rates, with each pest kept paired to its own quantity.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Rice target | Product / ha | Approx. / acre | Water / method | PHI |
|---|---|---|---|---|
| Stem borer | 18.75 kg | 7.59 kg | No dilution; granules | Confirm pack |
| Leaf folder | 18.75–25 kg | 7.59–10.12 kg | No dilution; granules | Confirm pack |
| Whorl maggot | 18.75–25 kg | 7.59–10.12 kg | No dilution; granules | Confirm pack |
Use a granule applicator or broadcast by hand while wearing rubber gloves, as stated in the leaflet. The formulation is used as supplied; do not turn the kilogram rate into a spray-tank concentration.
The leaflet’s harvest-interval column contains dashes. That does not mean a zero-day interval: confirm the applicable waiting period on the current pack before treatment. Its re-entry instruction is 48 hours.
Confirm crop-stage timing and any field-water management instructions on the supplied pack. No repeat interval, maximum application count or additional crop use is inferred.
How to Apply: Best Practices
- Identify the pest: Distinguish stem borer from leaf folder and whorl maggot before selecting the matching rate.
- Measure granules: Calibrate the amount to the field area; keep the original hectare rate as the reference.
- Apply as supplied: Use a granule applicator or hand broadcast with rubber gloves. Do not dissolve the product for foliar spraying.
- Observe waiting periods: Keep out of the treated area for the leaflet’s 48-hour re-entry period and confirm the harvest interval before treatment.
