Kollar Insecticide (Ethiprole 10.7% + Pymetrozine 40% WG)
The Ultimate Dual-Action Solution for Brown Plant Hopper (BPH) Control in Paddy
Kollar Insecticide by Crystal Crop Protection is a premium, next-generation solution designed specifically for Indian rice farmers. Born from a strategic alliance with Bayer Crop Science, Kollar combines two powerful active ingredients to fight "Hopper Burn" effectively. It offers a unique dual mode of action that targets pests that have developed resistance to older chemicals like Imidacloprid, ensuring your paddy harvest remains safe and profitable.

How It Works: Mode of Action
- Immediate Starvation (Pymetrozine): This component affects the insect's balance and hearing organs. The pest becomes confused and physically cannot insert its mouthpart into the plant. It stops feeding instantly, preventing yield loss.
- Nervous System Shutdown (Ethiprole): This acts as a GABA-blocker. It disrupts the insect's central nervous system, causing uncontrolled convulsions and paralysis.
- Complete Elimination: The combination ensures that pests die from both starvation and nervous exhaustion within 24 to 72 hours, cleaning your field completely.

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 Liters | 1.13 g | 26 Days |
| Paddy (High Density) | 170 g | 200 Liters | 0.85 g | 26 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Spray when you see 5 to 10 hoppers per hill (Economic Threshold Level). Avoid spraying if rain is expected within 2-4 hours.
- Mixing: Conduct a "Jar Test" before mixing with other chemicals. The granules dissolve easily, but thorough agitation is required.
- Coverage: The most critical success factor is water volume. Use at least 150-200 Liters of water per acre. Ensure the spray reaches the base (stem) of the plant where hoppers hide.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Avoid spraying near fish ponds.
Frequently Asked Questions
1. Does Kollar control resistant hoppers?
Yes. Because it uses Ethiprole and Pymetrozine, it works excellently against BPH populations that have developed resistance to Imidacloprid and other older pesticides.
2. Is Kollar safe for fish farming (pisciculture)?
No. The product label specifically states it is toxic to aquatic organisms. Do not use Kollar in paddy fields where fish are reared together (Rice-Fish system).
3. What is the pack size available?
The standard pack size is 170g, which is the exact dose required for one acre. Bulk packs of 500g are also available for larger farmers.
4. How fast does it work?
Pests stop feeding within hours of application (saving your yield immediately). Total mortality (death) of the pests happens within 1 to 3 days.
5. Can I mix Kollar with fungicides?
Kollar is generally compatible with common fungicides like "Mentor". However, always perform a physical compatibility test (small jar mix) before preparing the full tank.
