A Guide to the Use of Phosphine Fumigants
©2011 DEGESCH America, Inc.
Degesch America, Inc. (DAI) was founded in 1977 and is the United States arm
of German based Detia-Degesch Gmbh. Our corporate headquarters and
production facility are situated in the Shenandoah Valley town of Weyers Cave,
Virginia. This facility opened on March 15, 1979 and is the only producer of
aluminum phosphide (Phostoxin®) and magnesium phosphide (Magtoxin®)
fumigants in the United States.
DAI is the leader in specialized product packaging for the fumigation industry.
Products such as Phostoxin® Tablet Prepac & Prepac Rope , Magtoxin® Prepac
Spot Fumigant, Fumi-Cel®, Fumi-Strip®, Magtoxin® Granules and Detia®
Fumex are used extensively in the fumigation of food products.
DAI has pioneered the development of in-transit shipboard, railcar and barge
fumigations and is the developer of efficient modern techniques such as the
patented J-System® for land and shipboard use, the Degesch Phosphine
Generator and the Degesch Catalytic Adsorption Unit

Phostoxin
--------------------AlP + 3H2O > Al(OH)3 + Ph3
Aluminum phosphide reacts with ambient humidity (water) producing aluminum
hydroxide and phosphine.
Phostoxin also contains ammonium carbamate which reacts as follows:
NH2COONH4 >2NH3 + CO2
Ammonium carbamate releases ammonia and carbon dioxide.

Base Formula = L x W x H
Loft Formula = (L x W x H) ÷ 2
Base Volume: 80′ x 20′ x 20′ = 32,000 Ft3
Loft Volume: (80′ x 20′ x 10′) = 16,000 ÷ 2 = 8,000Ft3

A Certified Applicator must be physically present, responsible
for, and maintain visual and/or voice contact with all fumigation
Workers during the application of the fumigant. Once the
application is complete and the structure has been made secure
the certified applicator does not need to be physically present at
the site.
37
A Certified Applicator must be physically present, responsible for and
maintain visual and/or voice contact with all fumigation workers
during the initial opening of the fumigation structure for aeration.
Once the aeration process is secured and monitoring has established
that aeration can be completed safely the certified applicator does
not need to be physically present and trained person(s) can complete
the process and remove the placards.
38
Persons with documented training in the handling of phosphine products
must be responsible for receiving, aerating and removal of placards from
vehicles which have been fumigated in transit. Refer to section 12 for
training requirements.

44
The user must immediately report the theft of any
phosphine fumigants to the local police department
The registrant of the label must be informed by telephone of
any adverse incident to human health or the environment
involving their product so that records required by EPA can be
maintained
45
 Placards must withstand adverse weather conditions
 Placards must have the name of the fumigation company and a
24-hour emergency telephone number
 Placards must contain the EPA registration number of the product

The certified applicator is responsible for working with
the owners and/or responsible employees of the
structure and/or area to be fumigated to develop a
Fumigation Management Plan (FMP). The FMP is
intended to ensure a safe and effective fumigation. The
FMP must address characterization of the structure
and/or area, and include appropriate monitoring and
notification requirements……
