The ultimate post-harvest solution for total grain protection against weevils and storage pests.
Secure your hard-earned harvest with the trusted power of Celphos. Designed for superior post-harvest management, this 10g pouch formulation effectively eliminates stored grain pests, ensuring your agricultural commodities remain safe, clean, and marketable. It is the industry standard for protecting rice, wheat, and pulses in warehouses and silos.
Note: This is a Restricted Use Pesticide. It must be used only by trained experts or government-approved operators.
Why Choose This Product? Key Benefits
- ⏱️Fast-Acting Gas Release: The powder formulation reacts quickly with moisture to reach peak lethal concentration faster than tablets.
- 🛡️Total Pest Eradication: Effectively kills all life stages of insects, from eggs to adults, ensuring no regrowth of infestations.
- ⏳Residue-Free Pouch Design: The unique sachet traps the solid ash residue inside, ensuring your grain remains physically clean and free of dust.
- 🌧️High Penetration Power: Releases Phosphine gas ($PH_3$) that deeply penetrates grain stacks, reaching pests even in the center of the pile.
- 🌿Economical Protection: A highly affordable solution for bulk storage, costing a fraction of potential grain losses.
Technical Specifications

How It Works: Mode of Action
Celphos works through a chemical reaction called hydrolysis. It uses atmospheric moisture to trigger the release of the active fumigant.
- Moisture Activation: When the 10g pouch is exposed to air, the Aluminum Phosphide powder reacts with moisture to release Phosphine gas ($PH_3$).
- Systemic Attack: The gas enters the respiratory system of the insect. It targets the mitochondria (energy center) of the pest's cells.
- Total Elimination: By blocking energy production (ATP), it causes rapid paralysis and death of the pest.
Safety Feature: The formulation also releases Ammonia and Carbon Dioxide. The sharp smell of Ammonia warns humans of the gas presence, while $CO_2$ helps prevent fire hazards.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Cereals (Rice, Wheat) | Rice Weevil ($Sitophilus$ $oryzae$), Khapra Beetle |
| Pulses & Grains | Lesser Grain Borer ($Rhyzopertha$ $dominica$), Pulse Beetle |
| Storage Warehouses | Field Rats, House Rats, Bandicoots |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Ton" and ensure the storage area is 100% airtight.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop/Use | Dose (Qty / Unit) | Water (L / Acre) | Dose (ml / Litre) | Exposure (Days) |
|---|---|---|---|---|
| Bulk Grains (Silos/Sheds) | 10g (1 Pouch) per Metric Ton | N/A (Do not use water) | N/A (Solid Fumigant) | Min. 5 Days |
| Empty Godowns | 10g per Metric Ton Capacity | N/A | N/A | Min. 5 Days |
| Rat Burrows | ~3g (Partial Pouch) per Burrow | N/A | N/A | Seal for 24 hrs |
*Exposure = The time the area must remain sealed. Afterward, aeration is required until gas levels drop below 0.3 ppm.
How to Apply: Best Practices
- Timing: Apply only when the storage area is ready to be sealed immediately. Do not fumigate when temperatures are below 15°C.
- Sealing: Ensure 100% airtightness using LDPE sheets (sand snakes on edges) or by sealing silo vents. Gas leakage equals failure.
- Placement: Place the pouches evenly across the top of the stack or use a probe. Do not open the pouch; the gas permeates through the material.
- Safety: Always wear PPE (Full-face gas mask with phosphine canister, gloves). Never work alone. Wash hands thoroughly after use.
Frequently Asked Questions
1. Can I use this for home grain storage?
No. Celphos is a "Restricted Use Pesticide" and should only be used in commercial settings by trained government-approved experts due to high toxicity.
2. Does it leave toxic residue on the food?
No. When used correctly, the phosphine gas dissipates completely during aeration. The solid residue remains trapped inside the pouch, which is removed after fumigation.
3. How do I dispose of the used pouch?
The spent pouches contain Aluminum Hydroxide ash. They must be collected and disposed of according to local CIBRC guidelines, typically by deep burial in a safe location.
4. Is there an antidote for Celphos poisoning?
No, there is no specific antidote. Ingestion is a medical emergency. Immediate supportive care (like gastric lavage with coconut oil) in a hospital is required.
5. Can I mix it with water?
Absolutely not. Mixing Aluminum Phosphide with liquid water causes a violent reaction. It relies on atmospheric moisture (humidity) only.
Safety & Disclaimer
DANGER: Aluminum Phosphide is a deadly poison. Always read and follow the instructions on the official product label. The information provided here is for guidance only. Use personal protective equipment (PPE) during application. Keep away from children and livestock.
