Komugi Insecticide (Pyriproxyfen 10% EC)
The Ultimate Solution for Whitefly Control & Lifecycle Management
Komugi is a specialized insect growth regulator (IGR) brought to you by IFFCO-MC. Unlike standard poisons that only kill adult pests, Komugi uses advanced Japanese technology to break the reproductive cycle of the pest.
It effectively targets Whiteflies, Aphids, and Jassids by sterilizing adults and preventing nymphs from growing. This makes it an essential tool for protecting Cotton and Vegetable crops from resistant pest attacks.
Why Choose This Product? Key Benefits
- ⏱️Stops the Lifecycle: Prevents nymphs from molting into adults, effectively stopping population growth.
- ?️Japanese Quality: Manufactured by the IFFCO-MC joint venture, ensuring high purity and reliable results.
- ⏳Long-Lasting Control: Provides residual protection for 2 to 3 weeks, reducing the need for frequent sprays.
- ?️Translaminar Action: Penetrates the leaf surface to reach pests hiding on the underside of leaves.
- ?Egg Sterilization: Makes adult female pests lay sterile eggs that never hatch (Transovarial action).

How It Works: Mode of Action
Komugi works by mimicking the natural "youth hormone" in insects. It disrupts their biological clock in three ways:
- Inhibits Metamorphosis: It sends a fake signal to nymphs (young pests), preventing them from turning into adults. They remain as deformed nymphs and eventually die.
- Sterilizes Females: When adult females come in contact with Komugi, their reproductive system is damaged. They lay eggs that are sterile and will not hatch.
- Ovicidal Action: If sprayed directly on eggs, it stops the embryo inside from developing, preventing hatching entirely.
Note: This is a slow-acting product. You will see population reduction after 4-5 days, but damage stops earlier.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Cotton | Whitefly, Jassids |
| Chilli | Whitefly, Aphids |
| Brinjal & Okra | Whitefly, Jassids |
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 | 200 - 250 ml | 200 L | 1.5 - 2.0 ml | 31 Days |
| Chilli | 200 ml | 150 - 200 L | 1.5 ml | 7 Days |
| Brinjal / Okra | 200 ml | 150 - 200 L | 1.5 ml | 7 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 early in the season or when you see the first whitefly adults (ETL > 6 adults/leaf). It prevents the population from exploding.
- Mixing: Compatible with most insecticides like Bifenthrin or Diafenthiuron. DO NOT MIX with Malathion or Vapona (DDVP).
- Coverage: Use a Hollow Cone nozzle. Ensure the spray reaches the underside of the leaves where whitefly nymphs hide.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
