Pigeon Pea
The pigeon pea (''Cajanus cajan'') is a perennial legume from the family Fabaceae native to the Old World. The pigeon pea is widely cultivated in tropical and semitropical regions around the world, being commonly consumed in South Asia, Southeast Asia, Africa, Latin America and the Caribbean. Etymology and other names Scientific epithet The scientific name for the genus ''Cajanus'' and the species ''cajan'' derive from the Malay word ''katjang'' meaning legume in reference to the bean of the plant. Common English names In English they are commonly referred to as pigeon pea which originates from the historical utilization of the pulse as pigeon fodder in Barbados. The term Congo pea and Angola pea developed due to the presence of its cultivation in Africa and the association of its utilization with those of African descent. The names no-eye pea and red gram both refer to the characteristics of the seed, with no-eye pea in reference to the lack of a hilum on most varieties, u ...

Cercospora Cajani
''Cercospora'' is a genus of ascomycete fungi. Most species have no known sexual stage, and when the sexual stage is identified, it is in the genus ''Mycosphaerella''. Most species of this genus cause plant diseases, and form leaf spots. It is a relatively well-studied genus of fungi, but there are countless species not yet described, and there is still much to learn about the best-known of the species. Selected species *''Cercospora acetosella'' - found on sheep sorrel and other docks *''Cercospora aciculina'' *''Cercospora agerati'' *''Cercospora alabemensis'' *''Cercospora alismatis'' *''Cercospora althaeina'' *''Cercospora angreci'' - causes leaf spot of orchids *''Cercospora angulata'' *'' Cercospora apii'' - causes leaf spot on celery, and found on other plants, including ''Impatiens'' * ''Cercospora apii'' f.sp.

Colletotrichum Capsici
''Colletotrichum capsici'' is a species of fungus and plant pathogen which causes leaf blight on ''Chlorophytum borivilianum'', basil, chickpea and pepper as well as dieback in pigeonpea The pigeon pea (''Cajanus cajan'') is a perennial legume from the family (biology), family Fabaceae native to the Old World. The pigeon pea is widely cultivated in tropical and semitropical regions around the world, being commonly consumed in Sou ... and anthracnose in poinsettia. Hosts and symptoms ''Colletotrichum capsici'' has a broad host range but prefers peppers, yams and eggplants. On chili peppers, ''Capsicum annuum'' L., ''C. capsici'' infect the stem, fruit, and leaves of the plant, causing anthracnose, die-back and ripe fruit rot. ''C. capsici'' infection tends to infect ripe red fruit and lead to the development of brown necrotic lesions containing concentric acervuli that will eventually appear black from the setae and sclerotia (Srinivasan, Vijayalakshmi Kothandaraman, Vaikuntav ...

Pythium Splendens Var
''Pythium'' is a genus of parasitic oomycetes. They were formerly classified as fungi. Most species are plant parasites, but ''Pythium insidiosum'' is an important pathogen of animals, causing pythiosis. The feet of the fungus gnat are frequently a vector for their transmission. Morphology ;Hyphae: ''Pythium'' species, like others in the family Pythiaceae, are usually characterized by their production of coenocytic hyphae without septations. ;Oogonia: Generally contain a single oospore. ;Antheridia: Contain an elongated and club-shaped antheridium. Ecological importance ''Pythium''-induced root rot is a common crop disease. When the organism kills newly emerged or emerging seedlings, it is known as damping off, and is a very common problem in fields and greenhouses. Thus there is tremendous interest in genetic host resistance, but no crop has ever developed adequate resistance to ''Pythium''. This disease complex usually involves other pathogens such as ''Phytophthora'' and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pythium Aphanidermatum
''Pythium aphanidermatum'' is a soil borne plant pathogen. ''Pythium'' is a genus in the class Oomycetes, which are also known as water molds. Oomycetes are not true fungi, as their cell walls are made of cellulose instead of chitin, they are diploid in their vegetative state, and they form coenocytic hyphae (lacking crosswalls). Also, they reproduce asexually with motile biflagelette zoospores that require water to move towards and infect a host. Sexually, they reproduce with structures called antheridia, oogonia, and oospores. Hosts ''Pythium aphanidermatum'' has a wide host range, and can have an economic impact on the cultivation of soybeans, beets, peppers, chrysanthemum, cucurbits, cotton and turf-grasses, however, because ''P. aphanidermatum'' requires warmer temperatures, it is often seen in greenhouses and has a large impact in poinsettia production. It is a major cause of root rot in papaya production in subtropical areas. While this is almost exclusively a pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corticium Rolfsii
''Athelia rolfsii'' is a corticioid fungus in the family Atheliaceae. 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 specimens sent to him by Peter Henry Rolfs who considered the unnamed fungus to be the cause of tomato blight in Florida. The specimens sent to Saccardo were sterile, consisting of hyphae and sclerotia. He placed the species in the old form genus ''Sclerotium'', naming it ''Sclerotium rolfsii''. It is, however, not a species of ''Sclerotium'' in the strict sense. In 1932, Mario Curzi discovered that the teleomorph (spore-bearing state) was a corticioid fungus and accordingly placed the species in the form genus '' Corticium''. With a move to a more natural classification of fungi, ''Corticium rolfsii'' was transferred to '' Athelia'' in 1978. Description The fungus produces effused basidiocarps (fruit bod ...

Cladosporium Cladosporioides
''Cladosporium cladosporioides'' is a darkly pigmented mold that occurs world-wide on a wide range of materials both outdoors and indoors. It is one of the most common fungi in outdoor air where its spores are important in seasonal allergic disease. While this species rarely causes invasive disease in animals, it is an important agent of plant disease, attacking both the leaves and fruits of many plants. This species produces asexual spores in delicate, branched chains that break apart readily and drift in the air. It is able to grow under low water conditions and at very low temperatures. History and classification Georg Fresenius first described ''Cladosporium cladosporioides'' in 1850, classifying it in the genus ''Penicillium'' as ''Penicillium cladosporioides''. In 1880 Pier Andrea Saccardo renamed the species, ''Hormodendrum cladosporioides''. Other early names for this taxon included ''Cladosporium hypophyllum'', ''Monilia humicola'' and ''Cladosporium pisicola''. In 1952 ...

Cladosporium Oxysporum
''Cladosporium oxysporum'' is an airborne fungus that is commonly found outdoors and is distributed throughout the tropical and subtropical region, it is mostly located In Asia and Africa. It spreads through airborne spores and is often extremely abundant in outdoor air during the spring and summer seasons. It mainly feeds on decomposing organic matter in warmer climates, but can also be parasitic and feed on living plants. The airborne spores can occasionally cause cutaneous infections in humans, and the high prevalence of ''C. oxysporum'' in outdoor air during warm seasons contributes to its importance as an etiological agent of allergic disease and possibly human cutaneous phaeohyphomycosis in tropical regions. History and taxonomy This species was described by Reverend Miles Joseph Berkeley and Moses Ashley Curtis in 1868 in the Botanical Journal of the Linnean Society. Growth and morphology ''Cladosporium oxysporum'' expands moderately, often floccose at the center of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
