A mango is an edible stone fruit produced by the tropical tree Mangifera indica. It originated from the region between northwestern Myanmar, Bangladesh, and northeastern India. M. indica has been cultivated in South and Southeast Asia since ancient times resulting in two types of modern mango cultivars: the "Indian type" and the "Southeast Asian type". Other species in the genus Mangifera also produce edible fruits that are also called "mangoes", the majority of which are found in the Malesian ecoregion.
Plant pathology or phytopathology is the scientific study of plant diseases caused by pathogens and environmental conditions. Plant pathology involves the study of pathogen identification, disease etiology, disease cycles, economic impact, plant disease epidemiology, plant disease resistance, how plant diseases affect humans and animals, pathosystem genetics, and management of plant diseases.
Phytophthora palmivora is an oomycete that causes bud-rot of palms, fruit-rot or kole-roga of coconut and areca nut. These are among the most serious diseases caused by fungi and moulds in South India. It occurs almost every year in Malnad, Mysore, North & South Kanara, Malabar and other areas. Similar diseases of palms are also known to occur in Sri Lanka, Mauritius, and Sumatra. The causative organism was first identified as P. palmivora by Edwin John Butler in 1917.
Cephaleuros virescens is an algal plant pathogen that infects tea, coffee and coconut plants, causing algal leaf spot or algal rust.
Erythricium salmonicolor is a species of fungus in the family Corticiaceae. Basidiocarps are effused, corticioid, smooth, and pinkish and grow on wood. The fungus is a commercially significant plant pathogen which has become a serious problem, especially in Brazil. Erythricium salmonicolor causes Pink Disease, most commonly in Citrus, although E. salmonicolor has a wide host range including rubber and cacao trees. Pink Disease causes branch and stem die-back due to canker formation. The cankers are recognizable by gum exudation and longitudinal splitting of the bark.
Verticillium albo-atrum is a plant pathogen with many hosts.
Dothiorella aromatica is a fungal plant pathogen that causes fruit rot of avocado.
Dothiorella gregaria is a fungal plant pathogen.
Albonectria rigidiuscula is a fungal plant pathogen. The anamorph of A. rigidiuscula the fungus Fusarium decemcellulare is associated with inflorescence wilt and vascular necrosis in fruit tree crops such as Mango, Longan and Rambutan. F. decemcellulare causes a disease known as cushion gall in Theobroma cacao and other tropical trees.
Oidium mangiferae is a plant pathogen that infects mango trees causing powdery mildew. Powdery mildew of mango is an Ascomycete pathogen of the Erysiphales family that was initially described by Berthet in 1914, using samples collected from Brazil. O. mangiferae is found in all areas where mangoes have been raised long term, but is particularly widespread in India where both the host and the pathogen are native. Currently no teleomorph stage has been identified, but due to certain morphological characteristics it has been suggested that O. mangiferae belongs in the Erysiphe polygony group. Mango is the only known host for this pathogen, though O. mangiferae appears to be identical to fungi responsible for powdery mildew diseases on various other plant species, particularly oak, though some differences may be observed. In particular, the number of cells in conidiophores varies from 2 on mango to 3-5 on oak. O. mangiferae has been known to infect oak leaves in the laboratory, however due to the lack of a known teleomorph stage O. mangiferae is still considered to only be a pathogen of mango. Recent analysis of its ribosomal DNA suggests it is conspecific with Erysiphe alphitoides, the causative agent of powdery mildew in European oaks.
Glomerella cingulata is a fungal plant pathogen, being the name of the sexual stage (teleomorph) while the more commonly referred to asexual stage (anamorph) is called Colletotrichum gloeosporioides. For most of this article the pathogen will be referred to as C. gloeosporioides. This pathogen is a significant problem worldwide, causing anthracnose and fruit rotting diseases on hundreds of economically important hosts.
The 'Kensington Pride' mango is a named commercial mango cultivar that originated in Australia. It is sometimes called the KP, Bowen or Bowen special. It is Australia's most popular mango, accounting for over 80% of the country's annual commercial mango market. It is considered to have a distinctive flavour and aroma when compared with the Florida-bred cultivars grown by most mango-exporting countries.
The South American palm weevil, Rhynchophorus palmarum, is a species of snout beetle. The adults are relatively large black beetles of approximately one and a half inch in length, and the larvae may grow to two inches in length.
Fusarium mangiferae is a fungal plant pathogen that infects mango trees. Its aerial mycelium is white and floccose. Conidiophores on aerial mycelium originating erect and prostrate from substrate; they are sympodially branched bearing mono and polyphialides. Polyphialides have 2–5 conidiogenous openings. Phialides on the aerial conidiophores mono- and polyphialidic. Sterile hyphae are absent. Microconidia are variable in shape, obovoid conidia are the most abundant type, oval to allantoid conidia occurring occasionally. Microconidia mostly 0-septate with 1-septate conidia occurring less abundantly. Sporodochia are present. Macroconidia are long and slender, usually 3–5 septate. Chlamydospores are absent.
Grapevine trunk diseases (GTD) are the most destructive diseases of vineyards worldwide. Fungicides with the potential to control GTD have been banned in Europe and there are no highly effective treatments available. Action to develop new strategies to fight these diseases are needed.
Dothiorella moneti is an endophytic fungus that might be a canker pathogen, specifically for Eucalyptus gomphocephala. It was isolated from said trees in Western Australia.
Dothiorella santali is an endophytic fungus that might be a canker pathogen, specifically for Eucalyptus gomphocephala. It was isolated from said trees in Western Australia.
Dothiorella longicollis is an endophytic fungus that might be a canker pathogen, specifically for Adansonia gibbosa (baobab). It was isolated from said trees, as well as surrounding ones, in the Kimberley.
Dothiorella dulcispinae is an endophytic fungus that might be a latent plant pathogen. It was found on Acacia karroo, a common tree in southern Africa.
Dothiorella brevicollis is an endophytic fungus that might be a latent plant pathogen. It was found on Acacia karroo, a common tree in southern Africa.
