Soybean Rust

Scientific name: Phakopsora pachyrhizi, Phakopsora meibomiae

Common name: Soybean rust

USDA Confirms Soybean Rust in United States (Nov 10, 2004)

Soybean rust is a disease caused by two species of rust fungi (Basidiomycotina, Urediniomycetes), Phakopsora pachyrizi, which is considered more aggressive, and P. meibromiae. Both species are native to Asia, but have been introduced to Africa, Australia, South America, and Hawaii. Neither species is currently found in the continental U.S., but because the spores can be wind disseminated long distances, and because several susceptible host species occur through Central America, soybean rust could spread from infestations in South America to the continental U.S. within the current decade. In addition to the cultivated soybean, Glycine max, hosts of soybean rust comprise many other species of leguminous hosts, including wildland, weed, and cultivated food plants, woody and herbaceous species. One of the plant species affected by soybean rust is kudzu, itself an invasive plant in the U.S. that could serve as a bridge host for dispersal of soybean rust in the U.S. Soybean rust is of particular concern because of its high potential to reduce yields and increase production costs for U.S. agricultural crops.
