How It Works: Mode of Action
Loc 2.5 EC acts as a potent neurotoxin that targets the nervous system of the insect.
- Entry: The active ingredient penetrates the insect's cuticle (skin) or is ingested while feeding.
- Disruption: It binds to sodium channels in the nerve cells, keeping them open and causing uncontrollable repetitive nerve impulses.
- Elimination: This hyperexcitation leads to tremors, immediate paralysis (knockdown), and death of the pest.
Note: It is NOT a cholinesterase inhibitor, making it effective against pests resistant to organophosphates.

Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Cotton | 250 - 400 ml | 200 Litres | 1.5 - 2.0 ml | 21 Days |
| Rice (Paddy) | 200 ml | 200 Litres | 1.0 ml | 15 Days |

*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Spray in the late afternoon or evening. This protects beneficial pollinators like bees and prevents the sun (UV rays) from breaking down the chemical.
- Mixing: Use neutral water. Do NOT mix with alkaline substances (like Bordeaux mixture or Lime Sulphur) as this will destroy the product's efficacy.
- Coverage: Use a Hollow Cone nozzle for fine misting. Ensure the spray covers the undersides of leaves where pests hide.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Note: May cause temporary skin tingling (paresthesia); avoid cold water on skin if this happens.
