Mihir Insecticide (Pymetrozine 50% WG) by IIL
The Ultimate "Starvation" Solution for Brown Plant Hoppers (BPH) and Sucking Pests.
Mihir (Pymetrozine 50% WG) is a specialized systemic insecticide manufactured by Insecticides (India) Limited. Unlike traditional poisons that target the nervous system, Mihir uses advanced "starvation technology" to immediately stop pests like Brown Plant Hoppers (BPH), Aphids, and Whiteflies from feeding. It effectively locks their mouthparts, preventing crop damage and viral transmission instantly, making it the smart choice for Rice, Cotton, and Vegetable farmers.
Best For: Farmers facing BPH outbreaks in Paddy, "Sticky Cotton" issues, or viral transmission in vegetables.
Why Choose This Product? Key Benefits
- ⏱️Immediate Feeding Stop: The moment the pest touches Mihir, its mouthparts are paralyzed. It stops damaging your crop within minutes.
- ?️Virus "Chemical Quarantine": By stopping feeding instantly, it prevents pests from transmitting dangerous viruses (like Leaf Curl) to healthy plants.
- ⏳Long-Lasting Systemic Action: It absorbs into the plant's system (Translaminar & Xylem mobile), protecting new growth and hiding spots.
- ?️Excellent Rainfastness: Once dried (2-4 hours), it sticks to the plant and is not washed away by rain, ensuring safety during monsoons.
- ?Friend of the Farmer: Highly selective chemistry that kills pests but is safe for beneficial insects like spiders and ladybird beetles.

How It Works: Mode of Action
Mihir works differently than most insecticides. It targets the "balance and coordination" (chordotonal) organs of the insect.
- Contact/Ingestion: The pest comes into contact with the spray or ingests the sap.
- Paralysis: The chemical blocks the insect's ability to insert its needle (stylet) into the plant. They physically cannot suck sap anymore.
- Starvation: Although the pest may stay on the leaf for 2-4 days, it is harmless. It eventually dies of starvation and dehydration.
Note: This unique action makes it perfect for managing pests that are resistant to other chemicals.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Rice (Paddy) | Brown Plant Hopper (BPH), White Backed Plant Hopper (WBPH) |
| Cotton | Aphids, Whiteflies |
| Vegetables (Chili, Tomato, Okra) | Aphids, Whiteflies |
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 (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Rice (Paddy) | 120 - 150 g | 200 L | 0.6 - 0.75 g | 19 |
| Cotton | 120 - 150 g | 200 L | 0.6 - 0.75 g | 20 - 25 |
| Vegetables | 80 - 120 g | 200 L | 0.4 - 0.6 g | 7 - 14 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply at the Economic Threshold Level (ETL)—for Rice, this is when you see 5-10 hoppers per hill. Do not wait for "Hopper Burn" to start.
- Mixing: Ensure you use the recommended water volume (200 Litres per acre). Low water volume results in poor coverage and lower results.
- Coverage: For Rice, direct the spray nozzle toward the base of the plant (stem) where the hoppers hide. Use a Hollow Cone nozzle for best results.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. What is the difference between Mihir and Syngenta Chess?
Both contain the same technical molecule (Pymetrozine 50% WG). Mihir is a high-quality, cost-effective generic alternative manufactured by Insecticides (India) Ltd.
2. I sprayed Mihir, but the pests are still on the plant. Is it not working?
Don't panic! Mihir works by "starvation." The pest stops feeding immediately but may stay on the leaf for 2-4 days before dying. If they aren't moving much, the product is working.
3. Is Mihir safe for honeybees and spiders?
Yes, Mihir is highly selective. It kills pests but is relatively safe for beneficial insects like spiders, ladybirds, and bees (when not sprayed during active foraging hours).
4. Can I mix Mihir with other chemicals?
Yes, in high-pest situations, Mihir can be rotated or mixed with knockdown agents like Dinotefuran or Buprofezin (IGR) for resistance management.
5. What happens if it rains after spraying?
Mihir is rainfast within 2-4 hours. Once the spray dries on the leaf, it is absorbed and will not wash off.
