Kollar Insecticide (Ethiprole 10.7% + Pymetrozine 40% WG)
The Ultimate "Resistance Breaker" for Brown Plant Hoppers in Paddy
Struggling with stubborn hoppers that won't die with regular sprays? Kollar Insecticide by Crystal Crop Protection is your advanced solution. Developed through a strategic alliance with Bayer (similar to Curbix Pro), this Dual-Action formula combines the knockdown power of Ethiprole with the anti-feeding technology of Pymetrozine.
Best For: Farmers facing severe BPH (Brown Plant Hopper) and WBPH outbreaks who need to stop crop damage immediately.
Why Choose This Product? Key Benefits
- ⏱️Immediate "Stop-Feeding" Action: Pests stop eating your crop within hours of spraying, preventing "Hopper Burn" and viral transmission.
- ?️Resistance Breaker: Effectively kills hoppers that have developed immunity to older chemicals like Imidacloprid or Acephate.
- ⏳Dual-Mode Power: Combines paralysis (knockdown) with starvation to ensure high mortality rates within 1-3 days.
- ?️Rainfastness: Quickly absorbed by the plant; typically rainfast within 2 to 4 hours after application.
- ?Predator Safe: Designed to be safer for natural friends like Spiders and Mirid bugs, helping prevent pest resurgence.

How It Works: Mode of Action
Kollar attacks the pest from two different angles, ensuring they cannot survive:
- Immediate Starvation (Pymetrozine): Upon contact, it affects the insect's "Chordotonal Organs" (balance sensors). The pest feels "jammed," withdraws its mouthpart, and permanently stops feeding.
- Nervous System Shutdown (Ethiprole): This component blocks the GABA channels in the insect's nerves. This causes over-excitement, convulsions, and paralysis.
- The Result: The pest stops damaging your crop instantly (thanks to Pymetrozine) and dies from paralysis/starvation within 24-72 hours (thanks to Ethiprole).
Note: Because of the "Stop Feeding" action, you might see insects alive on the plant for a day or two, but they are harmless and will eventually fall off.

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) | 170 g | 150 - 200 L | ~ 1.13 g | 26 - 27 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 as soon as you see the pest population cross the threshold (5-10 insects per hill). Do not wait for visible "hopper burn."
- Mixing: The WG granules dissolve easily. However, always perform a "jar test" first if mixing with other fungicides or tonics.
- Coverage:Crucial! Hoppers stay at the bottom of the plant near the water level. Use sufficient water (150L+ per acre) to ensure the spray reaches the lower stem (the "hill").
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions

The 170g pack (one acre dose) typically costs between ₹800 to ₹936. Larger packs (500g) offer better value for bulk buyers.

4. Does it kill the eggs of BPH?
Kollar is primarily effective against nymphs and adults. Its main strength is stopping the adults from feeding and laying more eggs.
