Cassava
''Manihot esculenta'', common name, commonly called cassava, manioc, or yuca (among numerous regional names), is a woody shrub of the spurge family, Euphorbiaceae, native to South America, from Brazil, Paraguay and parts of the Andes. Although a perennial plant, cassava is extensively cultivated in tropical and subtropical regions as an annual crop for its edible starchy tuberous root. Cassava is predominantly consumed in boiled form, but substantial quantities are processed to extract cassava starch, called tapioca, which is used for food, animal feed, and industrial purposes. The Brazilian , and the related ''garri'' of West Africa, is an edible coarse flour obtained by grating cassava roots, pressing moisture off the obtained grated pulp, and finally drying it (and roasting in the case of both and ''garri''). Cassava is the third-largest source of carbohydrates in food in the tropics, after rice and maize, making it an important staple food, staple; more than 500 million pe ...

Phytophthora Erythroseptica
''Phytophthora erythroseptica''—also known as pink rot along with several other species of ''Phytophthora''—is a plant pathogen. It infects potatoes (''Solanum tuberosum'') causing their tubers to turn pink and damages leaves. It also infects tulips (''Tulipa'') damaging their leaves and shoots. Several species from the genus ''Phytophthora'' are believed to be involved in causing pink rot-like diseases. Disease cycle As ''Phytophthora erythroseptica'' is an oomycete, its disease cycle follows that of similar ''Phytophthora'' species. Oospores, sporangia, and zoospores can infect any part of the potato plant that is below ground. Oospores serve as the primary form of inoculum, and can survive in the soil as long as seven yearsWarton, Phillip., Kirk, William. Potato Diseases: Pink Rot (E2993). 31 January 2017. Michigan State University Extension http://msue.anr.msu.edu/resources/potato_diseases_pink_rot_e2993 Oospores produced in the field can overwinter and when thawed prod ...

Phytophthora Cryptogea
''Phytophthora cryptogea'' is a species of water mould in the family Pythiaceae. It is a plant pathogen that infects several species of cultivated plants, including over 40 species of cultivated flowers.Olson, H. A., et al. (2011)Phylogenetic history of ''Phytophthora cryptogea'' and ''P. drechsleri'' isolates from floriculture crops in North Carolina greenhouses.''Phytopathology'' 101(11) 1373–84. It was first described as the cause of tomato foot rot in tomatoes Host Range and Symptoms This species is reported to be pathogenic on grandiflora petunia (''Petunia'' × ''atkinsiana''). It causes root rot, shoot rot and shanking in tulips. It also infects blue daze ('' Evolvulus glomeratus''), dusty miller (''Jacobaea maritima''), Barberton daisy (''Gerbera jamesonii''), and garden verbena ( ''Verbena'' × ''hybrida''). Like its relative '' Phytophtora cambivora'', it can cause ink disease of chestnuts (''Castanea sativa''). The species is a cause of foot rot in tomatoes, caus ...

Verticillium Dahliae
''Verticillium dahliae'' is a fungal plant pathogen. It causes verticillium wilt in many plant species, causing leaves to curl and discolor. It may cause death in some plants. Over 400 plant species are affected by ''Verticillium'' complex. Management ''Verticillium dahliae'' has a wide host range and can persist as microsclerotia in the soil for years, so management via fallowing or crop rotation generally has little success. The exception to this is rotation using broccoli, which has been shown to decrease ''Verticillium'' severity and incidence in cauliflower fields. This is likely due to the production of allyl isothiocyanate in broccoli, which can suppress the growth of plant pathogenic fungi. Seed choice may reduce disease presence. Purchasing seed stock from certified ''Verticillium''-free growers and utilizing resistant or partially resistant cultivars can decrease disease incidence. Even resistant cultivars may show symptoms if the field has a high concentration o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sclerotium Rolfsii
''Agroathelia rolfsii'' is a corticioid fungus in the order Amylocorticiales. It is a facultative plant pathogen and is the causal agent of "southern blight" disease in crops. Taxonomy The species was first described in 1911 by Italian mycologist Pier Andrea Saccardo, based on a specimen collected by Peter Henry Rolfs, sent by John A. Stevenson at the US national mycological collection. Rolfs first considered the unnamed fungus to be the cause of tomato blight in Florida and subsequently caused diseases on multiple hosts. The specimens sent to Saccardo were sterile, consisting of hyphae and sclerotia. Saccardo placed the species in the old form genus ''Sclerotium'', naming it ''Sclerotium rolfsii''. It is, however, not a species of ''Sclerotium'' in the modern sense. In 1932, Mario Curzi discovered that the teleomorph (spore-bearing state) was a corticioid fungus and accordingly placed the species in the genus '' Corticium''. Uncertainty on its classification when the br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uromyces
''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. The genus is the second-largest plant pathogenic rust genus, which is responsible for various plant affecting diseases, and it has major effects on both agricultural and non-agricultural plants. The genus is generally characterized by its unicellular teliospores (thick-walled resting spores) that help to characterize it and distinguish it from another important and large rust genus, ''Puccinia''. The ''Uromyces'' fungal species have been recorded on various host plants belonging to a wide range of the families, including Asteraceae, Euphorbiaceae, Fabaceae, Liliaceae, Loranthaceae, and Poaceae. Family Loranthaceae is listed to be the most affected by the fungus. Species , the GBIF lists up to 1,048 species, while Species Fungorum list ...

Rigidoporus Microporus
''Rigidoporus microporus'' is a plant pathogen, known to cause white root rot disease on various tropical crops, such as cacao, cassava, tea, with economical importance on the para rubber tree (''Hevea brasiliensis''). White root rot of rubber ''Rigidoporus lignosus'' (klotzsch) Imazeki, the causal agent of white root rot, was first reported on rubber in 1904 from Botanical Gardens, Singapore. It belongs to the order Basidiomycete, and in the family Polyporaceae. The disease originates on roots and later spreads to collar region. Foliar symptoms are initiated subsequently with the destruction of the root system. Its above ground symptoms indicates that the trees are mostly beyond treatment and recovery, as rapid progress of infection makes death imminent. This disease caused significant mortality to tree irrespective of age or health status, causing economic losses to the latex industry in many countries. It is the most destructive root disease in rubber plantations in Sri Lanka a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
