Peronospora Americana
''Peronospora'' is a genus of oomycetes that are obligate plant pathogens of many eudicots. Most species in this group produce a downy mildew disease, which can cause severe damage to many different cultivated crops, as well as wild and ornamental plants. There are 19 genera that produce downy mildew, and ''Peronospora'' has been placed alongside '' Pseudoperonospora'' in the group of downy mildews with coloured conidia. ''Peronospora'' has far more species than any other genus of the downy mildews. However, many species have been moved from this genus to be reclassified to other or new genera. Among these was the most famous ''Peronospora'' species, formerly known as ''Peronospora parasitica'', and now known as ''Hyaloperonospora parasitica''. Now, the ''Peronospora'' species of most importance is likely the ''Peronospora tabacina''. ''Peronospora tabacina'' causes blue mold on tobacco plants and can severely reduce yields of this economically important crop to the point where it ...

Peronospora Manshurica
''Peronospora manshurica'' is a plant pathogen. It is a widespread disease on the leaves of soybeans and other crop plants. The fungi is commonly referred to as downy mildew, "leafspot", or "leaf-spot". Symptoms The most visible symptoms of ''P. manshurica'' are pale green to light yellow spots that enlarge into pale to bright yellow lesions of variable size and shape. Lesions later turn grayish-brown to dark-brown with a yellowish-green margin that may eventually become entirely brown. Tufts of grayish to pale-colored sporangiophores on the underside of leaves easily distinguish the infection from other foliar diseases. Disease cycle ''Peronospora manshurica'' commonly begins its disease cycle in the spring, with overwintering oospores mainly serving as the primary inoculum. This primarily occurs by the use of oospore encrusted seeds for planting. Oospores, and sometimes even mycelium, surviving on plant material can also serve as the primary inoculum. After the first infection ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
