Mythri Insecticide (Fipronil 7% + Hexythiazox 2% SC) - Coromandel
The Ultimate "Holistic" Solution for Chilli Thrips and Mites
Struggling with the devastation of "Murda" (Leaf Curl) in your Chilli, Cotton, or Vegetable crops? Coromandel Mythri is a premium, dual-action insecticide designed specifically to break the lifecycle of the sucking pest complex. By combining the knockdown power of Fipronil with the long-term egg-sterilizing ability of Hexythiazox, Mythri stops damage today and prevents resurgence tomorrow.
Best Used For: Controlling mixed infestations of Thrips (Scirtothrips dorsalis) and Mites (Red & Yellow) simultaneously.
Why Choose This Product? Key Benefits
-
⏱️
Instant Knockdown Power: Fipronil attacks the nervous system of adult pests, paralyzing them and stopping crop damage within hours.
-
🛡️
Stops Future Generations: Hexythiazox acts as an Insect Growth Regulator (IGR), sterilizing mite eggs so they never hatch.
-
⏳
Long-Lasting Protection: Offers "Holistic Control" that protects your crop for 21 to 30 days, reducing the need for frequent spraying.
-
🌧️
Excellent Rainfastness: The Suspension Concentrate (SC) formulation sticks firmly to leaves and resists wash-off from light rains after drying (3-4 hours).
-
🌿
Crop Safety (No Burn): A water-based SC formula that is gentle on tender leaves and flowers, unlike harsh solvent-based EC sprays.

How It Works: Mode of Action
Mythri attacks the pest on two different biological fronts, making it nearly impossible for pests to survive.
[Image of life cycle of red spider mite]- Nervous System Shutdown (Fipronil): Upon contact or ingestion, Fipronil blocks the chloride channels in the insect's nervous system. This causes hyperexcitation, paralysis, and rapid death of adult Thrips and Mites.
- Reproductive Sterilization (Hexythiazox): This component acts as birth control for mites. It penetrates the leaf and kills mite eggs (Ovicidal action) and stops larvae from molting into adults.
- The "Trans-Ovarian" Effect: Even if an adult female mite survives the spray, any eggs she lays afterwards will be sterile and will not hatch.
Result: The current population dies, and the next generation never hatches.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Chilli | Thrips, Yellow Mites (Polyphagotarsonemus latus), Red Spider Mites |
| Cotton | Thrips, Aphids, Whiteflies, Mites |
| Vegetables | Sucking Pest Complex (Thrips & Mites) |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Mites hide under leaves, so high water volume is critical.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Chilli | 400 ml | 200 Litres | 2 ml | 7 Days |
| Cotton | 400 ml | 200 Litres | 2 ml | 7 - 10 Days |
| Vegetables | 400 ml | 200 Litres | 2 ml | 7 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Essential for food safety.
How to Apply: Best Practices
- Timing: Spray at the first sign of pest infestation (ETL). Avoid spraying during the heat of the day.
- Mixing: Conduct a "Jar Test" if mixing with fungicides. Do NOT mix with alkaline products like Bordeaux Mixture or Lime Sulfur, as they will destroy the chemical.
- Coverage: Mites live on the underside of leaves. Ensure your nozzle is directed upwards or use high pressure to thoroughly drench the bottom of the leaves.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Do not spray when honeybees are active (forage in late evening).
Frequently Asked Questions
1. Why is Mythri better than just using Fipronil alone?
Fipronil kills adult pests but leaves eggs alive, leading to a bounce-back in population. Mythri includes Hexythiazox, which sterilizes the eggs, ensuring the infestation is wiped out completely.
2. Can I use Mythri during the flowering stage?
Yes, but with extreme caution. Fipronil is toxic to bees. You must spray only in the late evening when bees are not foraging to protect pollination.
3. What is the rainfastness of Mythri?
Mythri is a Suspension Concentrate (SC). Once the spray dries on the leaf (typically 3-4 hours), it binds well and is resistant to light rain.
4. Can I mix Mythri with other fungicides?
It is compatible with most neutral fungicides like Mancozeb or Azoxystrobin. However, strictly avoid mixing with alkaline substances (high pH) as they degrade the product.
5. How often should I use Mythri?
Do not use Mythri more than two times consecutively. Rotate with other chemicals (like Diafenthiuron or Abamectin) to prevent pests from developing resistance.
