HPM PaPro Insecticide (Buprofezin 15% + Acephate 35% WP)
The Ultimate Dual-Action Defense Against Rice Plant Hoppers
HPM PaPro is a scientifically engineered "divide and conquer" solution for paddy farmers. By combining two powerful active ingredients, it stops pests instantly and prevents future generations from hatching.
Best Used For: Controlling Brown Plant Hopper (BPH), White Backed Plant Hopper (WBPH), and preventing "Hopper Burn" in rice fields.
Why Choose This Product? Key Benefits
-
⏱️
Instant Knockdown Power: Contains Acephate to rapidly paralyze and kill adult hoppers upon contact or feeding.
-
🛡️
Stops Future Generations: Contains Buprofezin (IGR) which sterilizes eggs and stops nymphs from molting (growing).
-
⏳
Long-Lasting Protection: The systemic formula stays active within the plant, offering up to 20 days of residual control.
-
🌧️
Systemic Action: Absorbed by the plant to kill hidden pests sucking sap from the stem or leaf undersides.
-
🌿
Breaks Resistance Cycles: The dual-mode attack works even on pests that have developed resistance to single-chemical sprays.

How It Works: Mode of Action
PaPro utilizes a synergistic "Two-Pronged Attack" to eliminate pests at every life stage:
- Nervous System Overload (Acephate): It inhibits the enzyme Acetylcholinesterase (AChE), causing the insect's nerves to fire uncontrollably, leading to paralysis and death.
- Molting Inhibition (Buprofezin): It blocks Chitin synthesis. When young nymphs try to grow and molt, their new skin fails to form, and they die.
- Reproductive Sterilization: It suppresses egg-laying in adults and makes existing eggs unviable, ensuring the population crashes.
Note: This dual action makes it highly effective against pests that are resistant to standard sprays.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Paddy (Rice) | Brown Plant Hopper (BPH) |
| Paddy (Rice) | White Backed Plant Hopper (WBPH) |
| Paddy (Rice) | Green Leaf Hopper (GLH) |
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) | 500 g | 200 Liters | 2.5 g | 20 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 stages of hopper appearance (Early Tillering) to prevent population explosion.
- Mixing: Do NOT mix with alkaline products (like certain micro-nutrients) as this deactivates the Acephate.
- Coverage: Spray towards the base of the plant stem where hoppers reside. Use the full 200 Liters of water per acre for deep canopy penetration.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Toxic to bees and fish; avoid spraying near water bodies.
Frequently Asked Questions
1. What pests does PaPro control?
It is specifically designed for sucking pests in Rice, primarily Brown Plant Hoppers (BPH) and White Backed Plant Hoppers.
2. How does PaPro help with resistance?
It uses two different chemical methods (Buprofezin + Acephate) at once. If a pest is resistant to one, the other will still kill it.
3. Can I mix PaPro with other fertilizers?
You should avoid mixing it with alkaline (high pH) substances. Always perform a small jar test before mixing with other chemicals.
4. Does it kill insect eggs?
Yes. The Buprofezin component renders eggs unviable, meaning they will not hatch, stopping the next generation of pests.
5. When is the best time to spray?
Spray as soon as you see the first signs of hoppers, usually during the early tillering stage of the paddy crop.
