HPM PaPro Insecticide (Buprofezin 15% + Acephate 35% WP)
The Dual-Action Champion for Rice Hoppers
HPM PaPro is a scientifically engineered "divide and conquer" solution for tough pests. By combining two powerful active ingredients, it stops pests instantly and prevents future generations from hatching. It is the gold standard for protecting Paddy (Rice) crops from devastating Hopper Burn.
Why Choose PaPro? Key Benefits
- ⏱️Instant Knockdown: Contains Acephate to immediately paralyze and eliminate adult pests upon contact.
- ?️Future-Proof Protection: Contains Buprofezin (IGR) which sterilizes eggs and stops nymphs from molting, breaking the pest lifecycle.
- ?Systemic Action: Absorbed by the plant, turning the crop itself into a defense shield against hiding pests.
- ?Resistance Fighter: The unique dual-mix kills pests that have developed resistance to single-chemical sprays.
- ⏳Long Lasting: Provides extended residual control, keeping your fields safe for weeks after spraying.

How It Works: The "Double Engine" Effect
PaPro attacks the pest from two angles simultaneously, ensuring no escape:
- Nervous System Jamming (Acephate): It inhibits the enzyme acetylcholinesterase. Think of this as jamming the "off switch" of the insect's nerves, causing paralysis and rapid death.
- Growth Stoppage (Buprofezin): It acts as an Insect Growth Regulator (IGR). It stops the pest from forming a new skin (chitin). When young pests try to grow (molt), they die because they cannot form a new exoskeleton.
- Reproductive Block: It sterilizes adult females, meaning they lay fewer eggs, and the eggs that are laid fail to hatch.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Paddy (Rice) | Brown Plant Hopper (BPH), White Backed Plant Hopper (WBPH) |
| Cotton (Secondary) | Aphids, Jassids, Thrips, Whiteflies |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. High water volume is critical for reaching the base of the stems where Hoppers hide.
Dosage per Acre & Pre-Harvest Interval (PHI)
| Crop | Dose (Gram / Acre) | Water (L / Acre) | Dose (Gram / Litre) | PHI (Days) |
|---|---|---|---|---|
| Paddy (Rice) | 500 g | 200 L | 2.5 g | 20 Days |
*PHI = Pre-Harvest Interval: Stop spraying 20 days before you harvest the crop.
How to Apply: Best Practices
- Timing: Apply at the early stages of pest infestation (when you first see hoppers) to prevent "Hopper Burn."
- Target Zone: Hoppers live at the base of the plant. Direct the spray nozzle toward the lower stems and water surface, not just the top leaves.
- Mixing Warning: Do NOT mix with alkaline (high pH) substances like Bordeaux mixture or certain micro-nutrients, as this destroys the Acephate component.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Toxic to bees—avoid spraying during active foraging hours.
Frequently Asked Questions
1. What is PaPro used for?
It is primarily used to control Brown Plant Hoppers (BPH) and White Backed Plant Hoppers (WBPH) in rice fields.
2. Does PaPro kill eggs?
Yes. The Buprofezin component inhibits egg hatching and prevents nymphs from growing into adults.
3. Is this product systemic?
Yes. Acephate is systemic, meaning it enters the plant system and kills sucking pests even if they are hidden inside leaf sheaths.
4. Can I mix PaPro with other fungicides?
It is compatible with most standard neutral-pH chemicals, but strictly avoid mixing with alkaline products (lime/sulfur) as they neutralize the poison.
5. What is the waiting period before harvest?
You must wait at least 20 days after the last spray before harvesting the rice to ensure it is safe for consumption.
