Puccinia sorghi Schwein. 1832 - (maize rust)
This fungus causes an important rust disease of maize in tropical regions. It is less common in temperate countries where the obligatory intermediate hosts (Oxalis species) are usually not sufficiently abundant. Yield losses in maize can reach 50% (Zheng et al., 2018). Management is mainly directed at planting resistant cutivars.
The fungus passes through 5 spore stages, like other rust species. The elongated urediosori are formed on maize leaves, these turn dark brown when the spores are released. Afterwards, telia are also formed on maize. The spermagonial and aecial stages occur on Oxalis species.
