Trichoderma stromaticum [1] is a species of fungus in the family Hypocreaceae. [2] It is a parasite of the cacao witches broom pathogen and has been used in its biological control. [3]
Parasitism is a close relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. The entomologist E. O. Wilson characterised parasites as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the broomrapes.
Biological control or biocontrol is a method of controlling pests, whether pest animals such as insects and mites, weeds, or pathogens affecting animals or plants by using other organisms. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role. It can be an important component of integrated pest management (IPM) programs.
Botrytis cinerea is a necrotrophic fungus that affects many plant species, although its most notable hosts may be wine grapes. In viticulture, it is commonly known as "botrytis bunch rot"; in horticulture, it is usually called "grey mould" or "gray mold".
Witch's broom or witches' broom is a deformity in a woody plant, typically a tree, where the natural structure of the plant is changed. A dense mass of shoots grows from a single point, with the resulting structure resembling a broom or a bird's nest. It is sometimes caused by pathogens.
Tolypocladium inflatum is an ascomycete fungus originally isolated from a Norwegian soil sample that, under certain conditions, produces the immunosuppressant drug ciclosporin. In its sexual stage (teleomorph) it is a parasite on scarab beetles. It forms a small, compound ascocarp that arises from the cadaver of its host beetle. In its asexual stage (anamorph) it is a white mold that grows on soil. It is much more commonly found in its asexual stage and this is the stage that was originally given the name Tolypocladium inflatum.
In phytopathology, antagonism refers to the action of any organism that suppresses or interferes with the normal growth and activity of a plant pathogen, such as the main parts of bacteria or fungi.
Trichoderma viride is a fungus and a biofungicide.
Trichoderma is a genus of fungi in the family Hypocreaceae that is present in all soils, where they are the most prevalent culturable fungi. Many species in this genus can be characterized as opportunistic avirulent plant symbionts. This refers to the ability of several Trichoderma species to form mutualistic endophytic relationships with several plant species. The genomes of several Trichoderma specieshave been sequenced and are publicly available from the JGI.
Phytophthora megakarya is an oomycete plant pathogen that causes black pod disease in cocoa trees in west and central Africa. This pathogen can cause detrimental loss of yield in the economically important cocoa industry, worth approximately $70 billion annually. It can damage any part of the tree, causing total yield losses which can easily reach 20-25%. A mixture of chemical and cultural controls, as well as choosing resistant plant varieties, are often necessary to control this pathogen.
Moniliophthora perniciosa is a fungus that causes "witches' broom disease" (WBD) of the cocoa tree T. cacao. This pathogen is currently limited to South America, Panama and the Caribbean, and is perhaps one of the best-known cocoa diseases, thought to have co-evolved with cocoa in its centre of origin.
Moniliophthora roreri is a basidiomycete fungus that causes frosty pod rot disease, one of the most serious problems for cacao production in Latin America. This disease and together with witches’ broom disease and black pod rot constitute the cacao disease trilogy. It causes serious losses in southwestern parts of South America; spores are dry and powdery and are spread easily by water movement, wind, or movement of pods; disease spread is highest during periods of high rainfall.
Kretzschmaria deusta, commonly known as brittle cinder, is a fungus and plant pathogen found in temperate regions of the Northern Hemisphere on broad-leaved trees, also found in Argentina, South Africa, and Australia.
Theobroma bicolor, known commonly as the mocambo tree, jaguar tree, balamte, or pataxte, among various other common names, is a tree in the genus Theobroma, which also contains the better-known Theobroma cacao. It is found in Central and South America, including stretches of the Amazon rainforest in Brazil, Colombia, Ecuador, and Peru.
Black pod disease is a fungal disease of Cocoa trees. This pathogen if left untreated can destroy all yields; annually the pathogen can cause a yield loss of up to 1/3 and up to 10% of total trees can be lost completely.
Trichoderma longibrachiatum is a fungus in the genus Trichoderma. In addition to being a distinct species, T. longibrachiatum also typifies one of several clades within Trichoderma which comprises 21 different species. Trichoderma longibrachiatum is a soil fungus which is found all over the world but mainly in warmer climates. Many species from this clade have been adopted in various industries because of their ability to secrete large amounts of protein and metabolites.
A mycoparasite is an organism with the ability to parasitize fungi.
Trichoderma hamatum is a species of fungus in the family Hypocreaceae. It has been used a biological control of certain plant diseases, including Sclerotinia lettuce drop caused by Sclerotinia minor.
Trichoderma koningii is a very common soil dwelling saprotroph with a worldwide distribution. It has been heavily exploited for agricultural use as an effective biopesticide, having been frequently cited as an alternative biological control agent in the regulation of fungi-induced plant diseases. They are endosymbionts associated with plant root tissues, exhibiting mycoparasitism and promoting plant growth due to their capacity to produce different secondary metabolites.
Taphrina betulina is a fungal plant pathogen that causes the gall, witches broom, which is a chemical infection of birch buds or the developing shoots, leading to a proliferation of growth. It was first described by Emil Rostrup in 1883 and is found in Europe, New Zealand and North America.
