Aluminium Phosphide
Formulations based on aluminium phosphide (AlP) are the mostly used products for the control of pests in storages, as well for rodents and other outdoor vertebrates.
Aluminium phosphide is created by the fusion of aluminium und red or yellow phosphorus. In contact with ambient air and humidity the very efficient phosphine gas is developed and released.
Formulation
Pellets
Pellets contain of 56-57% aluminium phosphide as active substance and 43-44% inert components, mainly ammonium carbamate amongst others, that facilitate controlled outgassing of phosphine.
One pellet has a weight of 0.6 g and releases 0.2 g phosphine gas.
Round Tablets
Round Tablets contain of 56-57% aluminium phosphide as active substance and 43-44% inert components, mainly ammonium carbamate amongst others, that facilitate controlled outgassing of phosphine.
One round tablet has a weight of 3 g and releases 1 g phosphine gas.
Bags
Bag products contain of 57% aluminium phosphide as the active substance and inert components that facilitate controlled outgassing of phosphine. This formulation does not contain ammonium carbamate.
The formulation has been integrated in a special bag material (Tyvek) characterized by high levels of strength and elasticity. The Tyvek bag is only permeable to water vapour and phosphine and is practically impermeable to water in the liquid state.
One bag weighs 34 g and releases 11.3 g phosphine gas (see packaging for further information).
Packaging
Pellets and Round Tablets
UN-approved aluminium flasks in different flask sizes with specially sealed aluminium lid and plastic screw cap.
Content:
90/100 g, 250/300 g, 1,000 g net
Bags
The Tyvek bags are packed in gas-tight aluminium foil pouches of different sizes, depending on no. of bags, and are finally packed in UN-approved metal drums for transportation and storage.
Content:
Per aluminium foil pouch we offer pack sizes of one single bag of 34 g up to the so-called Bag Blankets (rolls of 100 bags of 34 g). Pack sizes can be provided with single bags and bags in chains, belts and blankets.
Application
Pellets and Round Tablets
The outgassing of the pellets and round tablets begins after a short delay once the fumigant gets into contact with product or ambient moisture. The outgassing rate depends on temperature and humidity levels.
The smaller dimensions of the pellets lead in a somehow more rapid outgassing compared to tablets.
All developmental stages of stored product pests as well as rodents on outdoor use can be controlled with phosphine.
The highly potent gas penetrates the commodities, also the ones which are densely packed and nearly all packaging materials.
Since phosphine reacts with noble metals such as silver, gold, copper and their compounds, these substances must be provided with sufficient protection during fumigation.
Fields of application:
Use of pellets and round tablets is not restricted to certain storage types as long as the storage unit can be made appropriately gas-tight. They are used in silos, on ships, in warehouses, containers, etc. and can be placed in the commodity to be treated manually or by using the Detia Freyberg Automatic Dispenser.
Bags
The bag material means additional control on the outgassing rate, so that Tyvek bags must never be opened during use. Time-delayed outgassing of phosphine begins as soon as the bags are removed from the aluminium foil pouch, once the fumigant gets into contact with product or ambient moisture. The outgassing rate depends on temperature and humidity levels.
This ensures an additional safety for the fumigation personnel.

Fields of application:
Single bags are particularly well-suited to fumigate a lot of venues in different sizes, from small spaces (single bags) up to large venues, f. e. ships, silos, flat storages, railcars, empty storages, etc., as long as the storage unit can be made appropriately gas-tight.
The bags can be applied directly into grains or other goods, during filling of silo cells f. e. In such cases they must be removed when the silo cells are emptied.
Due to the fact that no ammonium carbamate is used as inert component the bags are suitable for treatment of sensitive goods like cocoa, tobacco, spices, tea, etc.
The specialised packaging of this formulation avoids a direct contamination of fumigated goods by phosphide residues.
Safety
Phosphine is also highly toxic to humans and warm-blooded animals. It is therefore absolutely necessary to comply with the relevant safety measures. To raise the level of safety when the products are applied, special components have been included in the formulations to delay outgassing. The safety of Detia Freyberg fumigants is further optimized by the simplicity of their application. The products may only be used by specially trained personnel or under their supervision and always by following country-specific regulations/legislations.
Use biocides safely. Always read the label and product information before use.
Use plant protection products safely. Always read the label and product information before use.
