Peronosclerospora Philippinensis
Commonly known as Philippine downy mildew, this disease is caused by the species ''Peronosclerospora philippinensis'' of the fungal-like protist class Oomycetes, which also has members such as water molds and ''Phytophthora infestans'', which caused the potato blight that led to the Great Irish famine. Its hosts are typically grasses, cultivated and wild sorghum, sugarcane, and maize found in most of South and Southeast Asia, including India, China, and the Philippines. This disease results in reduced yield in crops, a withered appearance of the leaves, abortive reproductive structures, and a grayish down on the surfaces. Historically, there have been cases of epidemics in which the species infected cultivars of maize and sugarcane and decimated the populations, causing up to $23 million US dollars’ worth of damage. Because of this, the USDA Animal and Plant Health Inspection Service has included Philippine downy mildew on its Plant Pathogen Select Agent List, being a pathoge ...

Peronosporales
The Peronosporales are an order of water moulds (class Oomycetes) which can be pathogenic. Many diseases of plants are sometimes classified under this order, but are sometimes considered members of order Pythiales. Some of these pathogenic protists include the organisms responsible for potato blight, eucalyptus dieback, sudden oak death, and blue mold ''Peronospora hyoscyami'' f.sp. ''tabacina'' is a plant pathogen infecting tobacco that causes blue mold. It is an oomycete (a fungus-like organism) that is highly destructive toward seed plants. It is very prevalent in humid farming zones, .... Further genetic studies may place these organisms more definitively in one order or another. References Heterokont orders {{plant-disease-stub ...

Water Mould Plant Pathogens And Diseases
Water (chemical formula ) is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, despite not providing food, energy or organic micronutrients. Its chemical formula, H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. "Water" is also the name of the liquid state of H2O at standard temperature and pressure. A number of natural states of water exist. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds consist of suspended droplets of water and ice, its solid state. When finely divided, crystalline ice may precipitate in the form of snow. The gaseous state of water is steam or water vapor. Water co ...
