UNLABELLED SUMMARY Stem rust has been a serious disease of wheat, barley, oat and rye, as well as various important grasses including timothy, tall fescue and perennial ryegrass. The stem rust fungus, Puccinia graminis, is functionally an obligate biotroph. Although the fungus can be cultured with difficulty on artificial media, cultures grow slowly and upon subculturing they develop abnormal p...

Rust fungi (Basidiomycetes of the order Uredinales) are obligate biotrophs that grow and reproduce only in living plant tissue. There are on the order of 5000 or more species of rust fungi that collectively cause disease on most crops, ornamentals, and many other plants. For example, rusts caused by Puccinia species are some of the most important diseases of wheat and other small grain crops wo...

224 Journal of Plant Registrations, Vol 2, No. 3, September 2008 ‘Faller’ (Reg. No. CV-1026, PI 648350) hard red spring wheat (HRSW) (Triticum aestivum L.) was tested as experimental line ND805, developed at North Dakota State University (NDSU), and released by the North Dakota Agricultural Experiment Station (NDAES). In addition to researchers at NDSU, USDA-ARS researchers at Fargo, ND, contri...

The fungus Lecanicillium is belonging to the order Hypocreales and is described as anamorphic Cordycipitaceae. This genus is known by its ability to infect other species of fungi such as Agaricus spp., Sphaerotheca spp. [1], Puccinia spp. [2]...etc. On the other hand, it was recorded as entomopathogenic fungus as it can parasitize some species of insects like Mosquito larvae [3]&[4] Bombyx mori...

Stripe rust of wheat, caused by Puccinia striiformis f. sp. tritici, is one of the most important diseases of wheat worldwide. This review presents basic and recent information on the epidemiology of stripe rust, changes in pathogen virulence and population structure, and movement of the pathogen in the United States and around the world. The impact and causes of recent epidemics in the United ...
