Rusts are plant diseases caused by pathogenic fungi of the order Pucciniales.
Puccinia cacabata is a fungal species and plant pathogen that causes rust on cotton. It was originally found on the leaves of Chloris ciliata in Bolivia.
Puccinia schedonnardii is a basidiomycete fungus that affects cotton. More commonly known as a “rust,” this pathogen typically affects cotton leaves, which can decrease the quality of the boll at time of harvest. As large percentages of cotton in the United States are resistant to various rust varieties, there is little economic importance to this disease. In places where rust is prevalent, however, growers could see up to a 50% reduction in yield due to rust infection.
Puccinia striiformis is a fungal species and plant pathogen. It causes stripe rust on wheat, but has other hosts as well. The species is common in Europe and in more recent years has become a problem in Australia. Crop infections can cause losses of up to 40%, and the fungus will infect both winter wheat and spring wheat.
Puccinia menthae is a fungal plant pathogen that causes rust on mint plants. It was originally found on the leaves of Mentha aquatica.
Puccinia purpurea is a fungal species and plant pathogen that causes rust on sorghum. It is found in temperate places worldwide, excluding colder parts such as Russia and Canada.
Puccinia subnitens is a fungal species and plant pathogen that causes rust on Beta vulgaris. It was originally found on Distichlis spicata in Montana, USA.
Puccinia recondita is a fungus species and plant pathogen belonging to the order of Pucciniales and family Pucciniaceae.
Puccinia erianthi is a species of fungus and a plant pathogen. It was originally found on the leaves of Erianthus fulvus in Punjab, India. It is a common cause of sugarcane rust.
Puccinia pittieriana is a species of rust fungus. It is a plant pathogen which infects agricultural crops such as potato and tomato. Its common names include common potato rust and common potato and tomato rust.
Puccinia monoica is a parasitic rust fungus of the genus Puccinia that inhibits flowering in its host plant and radically transforms host morphology in order to facilitate its own sexual reproduction.
Puccinia bromina is a fungus species belonging to the order of Pucciniales and the family Pucciniaceae. It was originally found on Bromus arvensis in Sweden.
Uromyces is a genus of rust fungi in the family Pucciniaceae. The genus was described by Franz Unger in his 1833 work Die Exantheme der Pflanzen. They have a worldwide distribution but large occurrences happen in North America and Europe.
Puccinia malvacearum, also known as hollyhock or mallow rust, is a fungal species within the genus Puccinia known for attacking members of the family Malvaceae. An autoecious pathogen, it can complete its life cycle using a single host.
Puccinia poarum, is a species of fungus and known as the coltsfoot gall rust, or meadow grass rust, is a plant pathogen. This fungal parasite forms a yellow to orange gall, 1–2 cm in diameter, on the underside of leaves of coltsfoot. It also infects, but does not gall grasses of the family Poaceae. P. poarum is a genetically diverse species that has been reported on at least seventy plant hosts. It was originally found on Poa fertilis and Poa nemoralis in Denmark in 1877.
Puccinia sessilis is a fungal species and plant pathogen, which is also known as arum rust or ramsons rust. It commonly infects Arum maculatum and Allium ursinum causing yellow to orange circular patches on leaves. On the underside of the leaves, it produces raised orange aecia commonly covered in spores. It is common in Eurasia in the spring.
Pelargonium zonale is a species of Pelargonium native to southern Africa in the western regions of the Cape Provinces, in the geranium family. It is one of the parents of the widely cultivated plant Pelargonium × hortorum, often called "geranium", "horseshoe geranium", "zonal geranium" or "zonal pelargonium".
Puccinia umbilici is a fungal plant pathogen which causes rust on navelwort. It was originally found on the leaves of Umbilicus pendulinus in France. It is found in Europe, Japan, Russia and the United States.
Puccinia gansensis is a species of fungus and a plant pathogen. It was originally found on the leaves of on Achnatherum inebrians in Gansu, Japan.
