Aluminum Phosphide (Phostoxin) contains 56-57% aluminum phosphide as the active substance and 43-44% inert components that facilitate controlled outgassing of phosphine. The outgassing of the tablets begins after a brief delay once the fumigation product comes into contact with the product or ambient moisture. The outgassing rate depends on the temperature and humidity levels.
All developmental stages of stored product pests can be controlled with phosphine. The highly potent gas penetrates nearly all packaging materials and densely packed stored products. Since phosphine reacts with noble metals such as silver, gold, copper, and their compounds, these substances must be provided with sufficient protection from fumigation.
Aluminum Phosphide (Phostoxin) tablets and pellets are known for their ability to develop phosphine gas within a very short time on being exposed to the atmosphere, depending on the temperature and humidity.
Aluminum Phosphide (Phostoxin) can be used for the control of pests in grains such as rice, wheat, barley, maize, oats, sorghum, millet, rye, etc., leaf tobacco, processed foods, and animal feeds as well as flour, dried fruit, nuts, spices, oilseeds, confectionery, and biscuits. These commodities may be fumigated under gas proof sheets or in other sealed enclosures.
Aluminum Phosphide (Phostoxin) has been found effective against stored product insects and their preadult stages (eggs, larvae, and pupae). Insects controlled include grain and rice weevils, saw-toothed grain beetle, confused flour beetle. lesser grain borer, flat grain beetle, cadelle, khapra beetle, Indian meal moth. Mediterranean flour moth, cigarette beetle, and tobacco moth.
Aluminum Phosphide (Phostoxin) Active Ingredient(s)
56-57% aluminum phosphide, 43-44% inert components, majorly ammonium carbamate, which promotes the appropriate release of phosphine gas.
Aluminum Phosphide (Phostoxin) Packaging
Metal (aluminum) bottles each weighing 1 kg (333 round tablets each weighing 3 g).
Aluminum Phosphide (Phostoxin) Mode of Action
The product starts to produce phosphine gas in 30 to 60 minutes after the first contact with the atmosphere. The process dynamics depend on air temperature and humidity. Phosphine is effective against all pests of stored foodstuffs’ developmental stages, as well as some rodents that penetrate from the outside. The gas has a high penetrating ability; it diffuses rapidly throughout nearly all packaging materials as well as through tightly packed goods.
Aluminum Phosphide (Phostoxin) Function
The extermination of all pests of stored foodstuffs species and their larvae (granary weevers, rice weevils, flour beetles, flat bark beetles, sawtoothed grain beetles, rustic shoulder-knot moths, pea weevils, bean weevils, Indian meal moths, Mediterranean flour moths, Angoumois grain moths, flour mites, as well as a number of quarantine insect species).

Application of Aluminum Phosphide (Phostoxin)
The pellets can be stationed by hand or by using an appropriate dispenser for all suitable storage, including:
- Silo installations (apply the pellets during filling)
- Storage Containers
Correct Dosage of Aluminum Phosphide (Phostoxin)
The correct dosage and the appropriate exposure time are dependent on certain factors like temperature and humidity, the nature of storage sealing, product packing, and the species of storage pest to be exterminated.
Benefits of using Aluminum Phosphide (Phostoxin)
- It does not deplete the ozone layer.
- No special training is required to apply it as it is safe and easy to apply.
- Highly effective in the control of storage pests in all their stages of eggs and pupae.
- Occupational safety.
Aluminum Phosphide (Phostoxin) Certifications
- Do not use when commodity temperature is below 15oC and/or the relative humidity within the structure is high or with row cereal grain, the moisture content should be less than 9%.
