Phakopsora pachyrhizi is an obligate biotrophic pathogen that causes Asian soybean rust. Phakopsora pachyrhizi is able to affect up to 31 different plant species that belong to 17 different genera under natural conditions. Experiments in laboratories were able to use P. pachyrhizi to infect 60 more plant species.

Soybean rust is caused by two types of fungi, Phakopsora pachyrhizi and Phakopsora meibomiae. [6] It affects several important commercial plants, however, most notable for soybeans. Asian Soybean Rust can infect and reproduce on 90 known plant species, 20 of which are found in the United States, such as, soybeans, dry beans, kidney beans, peas ...

This fungus species has undergone various name changes. Originally described in 1957, from soyabean leaf lesions and it was classified as a new species in the genus Pyrenochaeta , published as Pyrenochaeta glycines R.B. Stewart , due to the pycnidial stage (when shaped like a bulging vase) (Stewart, 1957). [ 6 ]
This fungus infects over 530 species of plants [1] in 53 families. [2] In the tropics and subtropics, it is most common. [1] It has also been isolated from nematodes and from human skin. [1] The fungus is known as a pathogen of many agricultural crop plants, especially cowpea, cucumber, papaya, rubber, soybean, and tomato.
The fungus has more of a damaging impact when infection occurs before or at flowering (Lin and Kelly, 2018 [2]). Fungal infection occurs with direct contact from an already infected soybean pod but the fungus can also spread from seed to seed during plant growth. [2]
Phialophora gregata is a Deuteromycete [1] fungus that is a plant pathogen which causes the disease commonly known as brown stem rot of soybean. P. gregata does not produce survival structures, but has the ability to overwinter as mycelium in decaying soybean residue.
