White mold affects a wide range of hosts and causes sclerotinia stem rot. It is known to infect 408 plant species. As a nonspecific plant pathogen, [2] diverse host range and ability to infect plants at any stage of growth makes white mold a serious disease. The fungus can survive on infected tissues, in the soil, and on living plants.
Phytophthora cinnamomi, also known as cinnamon fungus, is a soil-borne water mould [1] that produces an infection which causes a condition in plants variously called "dieback", "root rot", or (in certain Castanea species), "ink disease". Once infected soil or water is introduced, the organism can spread rapidly throughout an environment.
Mold spores are drawn to specific environments, making it easier for them to grow. These spores will usually only turn into a full-blown outbreak if certain conditions are met. [32] Various practices can be followed to mitigate mold issues in buildings, the most important of which is to reduce moisture levels that can facilitate mold growth. [27]
Within the United States, approximately 13,000 species of microfungi on plants or plant products are thought to exist. Specimens of microfungi are housed in the U.S. National Fungus Collections and other institutions like herbaria and culture collections that serve as reservoirs of information and documentation about the nation's natural heritage.
Aspergillus niger is a mold classified within the Nigri section of the Aspergillus genus. [1] The Aspergillus genus consists of common molds found throughout the environment within soil and water, on vegetation, in fecal matter, on decomposing matter, and suspended in the air. [2]
Rain can wash spores into the soil where they infect young tubers, and the spores can also travel long distances on the wind. The early stages of blight are easily missed. Symptoms include the appearance of dark blotches on leaf tips and plant stems. White mold will appear under the leaves in humid conditions and the whole plant may quickly ...
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".
In addition to growth on carbon sources, many species of Aspergillus demonstrate oligotrophy where they are capable of growing in nutrient-depleted environments, or environments with a complete lack of key nutrients. Aspergillus niger is a prime example of this; it can be found growing on damp walls, as a major component of mildew. [citation ...
