Product scienceHow It Works: Mode of Action

Koranda works via "Synergistic Potentiation," meaning the two chemicals work better together than alone (The 1+1=3 Effect).

  1. Nervous System Attack: Chlorpyrifos targets the enzyme Acetylcholinesterase (AChE), causing the insect's nerves to fire uncontrollably, leading to paralysis.
  2. Sodium Channel Block: Cypermethrin attacks the nerve axon channels, creating an immediate electrical shock that knocks the insect off the plant.
  3. Metabolic Synergism: Chlorpyrifos prevents the insect from detoxifying Cypermethrin, making the spray lethal even to semi-resistant pests.

This multi-site attack ensures that the insect cannot recover from the initial shock.

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 (ml / Litre)PHI (Days)
Cotton400 - 500 ml200 L2.0 - 2.5 ml15
Paddy350 - 400 ml200 L2.0 ml15 - 30
Vegetables200 - 300 ml150 L1.5 - 2.0 ml7

*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.

Useful detailsHow to Apply: Best Practices
  • Timing: Use as a "rescue spray" when pest population crosses the economic threshold (ETL). Avoid spraying during full bloom to protect bees.
  • Mixing: Pour the required dose into a small amount of water first to create a white emulsion, then add the remaining water.
  • Coverage: Ensure uniform coverage. For Paddy Stem Borer, maintain 2-3 inches of water in the field to maximize vapor action.
  • Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. This product is toxic to fish and bees; do not spray near water bodies.
