How It Works: Mode of Action
Katappa operates via a unique nervous system blockade mechanism derived from marine sources.
- Systemic Action (The Internal Guardian): The granules dissolve in water/soil and are absorbed by the plant roots. The toxin travels through the xylem to the stems and leaves, making the plant itself poisonous to borers.
- Stomach Action (Ingestion): When larvae (like Leaf Folders) eat the treated plant, the chemical blocks their nerve transmission. The pest stops feeding immediately and dies of starvation.
- Contact Action (The Shield): Pests that crawl over the treated soil or granules absorb the toxin through their skin (cuticle), leading to paralysis.
Result: Rapid paralysis and death of the pest, ensuring minimal crop damage.
Target Crops & Pests

Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Since this is a Granular (GR) product, it is applied by broadcasting (spreading), not spraying.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (kg / Acre) | Water (L / Acre) | Method | PHI (Days) |
|---|---|---|---|---|
| Paddy (Rice) | 7.5 kg - 10 kg | N/A | Broadcast in standing water | 20-30 |
| Sugarcane | 10 kg - 12 kg | N/A | Soil Application / Root Zone | 45+ |
| Onion / Chilli | 7.5 kg - 10 kg | N/A | Soil Broadcast | 15-20 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing (Paddy): For best results in Rice, apply 10 days after transplanting (early vegetative stage).
- Mixing: This product is ready-to-use. Do not mix with water. You can mix it with sand or fertilizer for easier spreading if required.
- Coverage: Ensure 2-3 cm of standing water in the field when applying to Paddy. This helps the granules dissolve and reach the roots.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not inhale the dust.
Frequently Asked Questions
1. How does Katappa (Cartap Hydrochloride) control Stem Borers?
It works systemically. The plant absorbs the chemical, so when the borer tries to eat the stem from the inside, it ingests the toxin and dies.
2. Can I mix Katappa granules with Urea or DAP?
Yes, Katappa granules are generally compatible and can be mixed with fertilizers like Urea for easier broadcasting in the field.
3. Is this product safe for spiders in my field?
Yes, unlike many sprays, granular Cartap Hydrochloride is relatively safe for beneficial insects like spiders and mirid bugs, making it great for IPM.
4. Do I need to spray this product?
No. This is a Granular (GR) formulation. It should be broadcasted (thrown) by hand or spreader directly into the field/soil.
5. What is the price of a 50kg bag?
While prices fluctuate, a 50kg bulk order is generally more economical, costing approximately ₹98 per kg (Subject to market rates).
