HPM Pymetro Plus (Pymetrozine 50% WG) - The BPH Expert
Stop Brown Plant Hoppers (BPH) instantly with the power of Pymetrozine.
Rice farming is hard work, and the Brown Plant Hopper (BPH) is your biggest enemy. It drains plant sap, causes "Hopper Burn," and spreads deadly viruses. HPM Pymetro Plus is a specialized systemic insecticide designed specifically for Paddy. It acts like a "lock-jaw" for pests—stopping them from feeding immediately upon contact.
Best For: Farmers looking for a cost-effective, high-quality solution to save their paddy crop from BPH and prevent viral diseases.
Why Choose This Product? Key Benefits
-
⏱️
Stops Feeding Instantly: Unlike other poisons, Pymetro Plus paralyzes the insect's mouth immediately. They stop damaging your crop within minutes.
-
🛡️
Viral Disease Shield: By stopping feeding, it prevents the hopper from injecting viruses like Rice Grassy Stunt and Ragged Stunt into your plants.
-
⏳
Long-Lasting Protection: One spray provides protection for 15 to 20 days, saving you money on repeat sprays.
-
🌧️
Systemic Action: It moves inside the plant (Systemic & Translaminar). It reaches pests hiding at the base of the stem or under the leaves.

How It Works: Mode of Action
Pymetro Plus works differently from older pesticides. It targets the insect's nervous system responsible for feeding.
- Contact & Ingestion: The pest touches the treated plant or tries to suck the sap.
- Immediate Blockage: The chemical blocks the "Chordotonal Organs." The insect's stylus (mouthpart) gets locked.
- Starvation: The insect cannot eat anymore. It remains alive but harmless for 2-4 days before dying of starvation.
Note: You might see live insects for a few days after spraying, but do not worry—they are not feeding or damaging your crop.

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) |
|---|---|---|---|---|
| Paddy (Rice) | 120g - 150g | 200 Litres | 0.6 g/L | 19 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting. Do not spray within 19 days of harvest, especially for export Basmati.
How to Apply: Best Practices
- Timing: Apply as soon as you see the pest (Economic Threshold Level: 5-10 hoppers per hill). Do not wait for severe damage.
- Mixing: The WG granules dissolve easily. Mix with clean water. Do not mix with highly alkaline chemicals like Bordeaux mixture.
- Coverage: Use 200 Litres of water per acre. Ensure the spray reaches the base of the stem where BPH hides.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. I sprayed Pymetro Plus, but the insects are still alive. Is it working?
Yes! The insects stop feeding immediately (Lock-Jaw effect) so your crop is safe. They will starve and die within 2 to 4 days.
2. Is this product safe for fish farming in paddy fields?
No. Pymetrozine is toxic to aquatic life (fish, crayfish, water fleas). Do not use where water flows directly into fish ponds.
3. Can I mix Pymetro Plus with other fungicides?
Yes, it is generally compatible with common rice fungicides like Tricyclazole or Hexaconazole. Always do a small jar test first.
4. Does rain affect the result?
Pymetro Plus is systemic (absorbed by the plant). Once absorbed (usually within a few hours), it is rain-fast and won't wash away easily.
5. Why is this better than cheap sprays?
Cheap sprays often kill spider predators, causing BPH to return even stronger (Resurgence). Pymetro Plus spares the spiders, giving you longer natural control.
