Komugi Insecticide (Pyriproxyfen 10% EC): Complete Guide for Whitefly Control
Stop resistant pests in their tracks with IFFCO-MC's advanced Insect Growth Regulator (IGR).
Komugi (Pyriproxyfen 10% EC) is a specialized insecticide designed to break the lifecycle of tough sucking pests like Whiteflies and Aphids. Unlike traditional poisons that only target adults, Komugi acts as a "population suppressor." It mimics natural insect hormones to sterilize female pests and stop eggs from hatching.
Best For: Cotton, Chilli, Brinjal, and Okra farmers facing resistance issues with older chemicals.

How It Works: Mode of Action
Komugi works as an Insect Growth Regulator (IGR). It does not kill instantly like a neurotoxin; instead, it disrupts the insect's endocrine system.
- Egg Inhibition: When sprayed on eggs (ovicidal action), it prevents them from hatching.
- Metamorphosis Failure: It mimics the "Juvenile Hormone," tricking nymphs into staying in the larval stage. They fail to molt into adults and eventually die.
- Transovarial Sterilization: Adult females exposed to Komugi lay sterile eggs that will never hatch, effectively crashing the future population.
Note: It has Translaminar action, meaning it penetrates the leaf surface to reach pests hiding on the underside.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Cotton | Whitefly (Bemisia tabaci) |
| Chilli | Whitefly, Aphids |
| Brinjal & Okra | Whitefly, Jassids (Leafhoppers) |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Dilution ratios can vary based on your pump size.
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 | 1.25 ml/L | 31 Days |
| Chilli | 200 ml | 150 - 200 L | 1.5 ml/L | 7 Days |
| Brinjal / Okra | 200 ml | 150 - 200 L | 1.5 ml/L | 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 pest population reaches the threshold (ETL of 6 adults/leaf). Early morning or late evening is best.
- Mixing: Compatible with most fungicides/insecticides (e.g., Bifenthrin for knockdown). Do NOT mix with Malathion or Vapona (DDVP).
- Coverage: Use hollow cone nozzles to ensure fine mist. Direct the spray to the underside of leaves where whiteflies hide.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying during peak bee foraging hours.
Frequently Asked Questions
1. Does Komugi kill Whiteflies immediately?
No. Komugi is an IGR (Insect Growth Regulator). It stops reproduction and egg hatching. For instant results (knockdown), mix it with Bifenthrin.
2. Can I use Komugi on vegetables?
Yes, it is highly effective on Chilli, Brinjal, and Okra with a short waiting period (PHI) of just 7 days.
3. What is the price of Komugi per acre?
It is very economical, typically costing between ₹300 to ₹350 per acre, making it cheaper than many patent chemistries.
4. How does it help against viruses?
Whiteflies spread the Cotton Leaf Curl Virus (CLCV). By sterilizing the whiteflies, Komugi reduces the vector population, indirectly controlling the virus spread.
5. Is it safe for honey bees?
It is relatively safe for adult bees but can affect larvae. To be safe, spray in the late evening when bees are not foraging.
