Suruga Insecticide (Pymetrozine 50% WG): Expert BPH Control by IFFCO-MC
The Ultimate "Hopper Burn" Prevention Tool for Modern Rice Farming.
Suruga (Pymetrozine 50% WG) is a specialized, biorational insecticide designed to stop sucking pests instantly. Unlike old chemicals that cause pest resurgence, Suruga uses "Zombie Technology" to stop pests from feeding immediately, protecting your paddy, cotton, and vegetables from severe damage and viral diseases.
Best For: Farmers facing Brown Plant Hopper (BPH) resistance or Whitefly infestations who want to protect their yield and beneficial farm insects.

How It Works: Mode of Action
Suruga works differently than standard poisons. It targets the nervous system responsible for the insect's balance and feeding muscles (Chordotonal Organs).
- Immediate Block: Upon contact or ingestion, Suruga binds to the insect's nerve receptors, creating a "false signal."
- Stylet Withdrawal: The pest loses muscle coordination and involuntarily removes its mouthpart (stylet) from the plant tissue.
- Starvation Death: Unable to feed or probe the plant again, the pest dies of starvation and dehydration within 2-4 days.
Note: You may see pests moving on the plant after spraying, but they are unable to feed or damage the crop.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Rice (Paddy) | Brown Plant Hopper (BPH), WBPH, GLH |
| Cotton | Whiteflies, Aphids, Jassids |
| Vegetables (Tomato, Chili, Potato) | Aphids (Myzus persicae), Whiteflies |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Using less water is the #1 cause of failure in BPH control.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Rice (Paddy) | 120g - 133g | 200 L | 0.6 g/L | 19-20 Days |
| Cotton | 120g - 150g | 200 L | 0.6 g/L | 25 Days |
| Vegetables | 120g | 200 L | 0.6 g/L | 7-14 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 at the Early Tillering to Booting stage when you see 5-10 hoppers per hill (ETL).
- Mixing: Dissolve the granules in a small quantity of water first, then add to the main tank. It disperses quickly ("bloom effect").
- Coverage: Direct the nozzle towards the base of the plant. BPH hides near the water level, so spray must penetrate the canopy.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying when bees are actively foraging.
