Subject: United States takes the threat of soybean rust (Phakopsora pachyrhizi) very seriously
Date posted: February 04, 2003
Source: Florida Pest Alert, ProMed, USDA-APHIS-PPQ
The Australasian soybean rust fungus Phakopsora pachyrhizi has yet to reach the continental United States, but US soybean growers are anticipating its arrival. Phakopsora pachyrhizi has a widespread distribution including parts of Africa, Asia, Oceania, South America, and the United States (Hawaii only, in 1994). Once spores from P. pachyrhizi enter the atmosphere, they are readily wind dispersed. It is estimated that soybean rust could adversely affect all soybean varieties in the United States at an estimated cost of $7.2 billion US dollars.

The Florida Division of Plant Industry has created a one-page web site on soybean rust with photographs to prepare for this possibility.
The site is available from the Florida Pest Alert at:

Recently, there was an additional outbreak of P. pachyrhizi reported in Sao Paulo State, Brazil. For more information, see the full ProMed article at:
