Product scienceHow It Works: Mode of Action
[Image of insect muscle structure diagram]
Katana works by targeting the insect's muscle system, specifically the Ryanodine Receptors (RyRs).
- Ingestion: The larva eats the treated leaf or stem.
- Calcium Flood: The chemical locks the calcium channels in the insect's muscles "open," causing a massive release of calcium.
- Paralysis: The muscles contract uncontrollably and then become paralyzed. The pest stops feeding immediately and dies within 24-72 hours.
This unique action makes it effective even against pests resistant to older sprays like pyrethroids.

How to applyDosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results.
How to applyDosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (gm / Litre) | PHI (Days) |
|---|---|---|---|---|
| Rice (Paddy) | 70 gm | 150 - 200 L | 0.35 - 0.5 gm | 40 |
| Cotton | 100 gm | 200 L | 0.5 gm | 30 |
| Tomato / Cabbage | 40 - 100 gm | 200 L | 0.5 gm | 5 - 7 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
Useful detailsHow to Apply: Best Practices
- Timing: Spray at the early stages of pest infestation (egg hatching or early larval stage). Apply in the morning or evening to avoid strong sun.
- Mixing: Dissolve the granules in a small mug of water first to make a solution, then add it to the main tank. It disperses easily.
- Coverage: Ensure full coverage of the crop canopy. For Rice, use 150-200 Litres of water per acre for best results.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
