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).

  1. Ingestion: The larva eats the treated leaf or stem.
  2. Calcium Flood: The chemical locks the calcium channels in the insect's muscles "open," causing a massive release of calcium.
  3. 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)
CropDose (ml / Acre)Water (L / Acre)Dose (gm / Litre)PHI (Days)
Rice (Paddy)70 gm150 - 200 L0.35 - 0.5 gm40
Cotton100 gm200 L0.5 gm30
Tomato / Cabbage40 - 100 gm200 L0.5 gm5 - 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.
