How It Works: Mode of Action
Iruka uses a unique "ZC Technology" that encapsulates the chemical to protect it from sunlight and release it effectively.
- Systemic Action (Thiamethoxam): It is absorbed by the leaves and roots, moving upward through the plant's water pipes (xylem). It kills hiding pests like aphids and jassids when they suck the sap.
- Contact Action (Lambda-cyhalothrin): It stays on the leaf surface. Any caterpillar or beetle that touches or eats the treated leaf is instantly paralyzed.
- Nervous System Attack: The combination attacks the insect's nervous system at two different points, making it very difficult for pests to survive or develop resistance.
Result: Complete protection from "Shoot to Root."

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 | 80 ml | 200 L | 0.4 - 0.5 ml | 26 Days |
| Maize | 50 ml | 200 L | 0.25 ml | 42 Days |
| Chilli / Tomato | 50 - 60 ml | 200 L | 0.3 ml | 3 - 5 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply when you first see the pests reach the Economic Threshold Level (ETL). Avoid calendar spraying.
- Mixing: Use clean water. Fill the tank halfway, add the dose, mix well, and fill the rest.
- Coverage: Ensure the spray covers the underside of leaves where pests hide. Do not spray during flowering to protect bees.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Does Iruka control Pink Bollworm?
It is effective against moths and young larvae. However, for larvae already inside the boll, efficacy is limited. It works best as a preventive measure.
2. Is Iruka rainfast?
Yes, thanks to its ZC formulation, it binds to the leaf surface quickly and resists wash-off from light rains after drying.
3. Can I use Iruka on all vegetables?
It is registered for specific crops like Chilli, Tomato, and Brinjal. Always check the PHI (Waiting Period) before using on harvest-ready vegetables.
4. Does it harm honeybees?
Yes, it is toxic to bees. Do not spray when your crop or nearby weeds are flowering and bees are active.
5. Why do my plants look greener after spraying?
The Thiamethoxam in Iruka provides a "Thionic effect," which boosts photosynthesis and root growth, making the crop look healthier and greener.
