Other species of Botrytis may be present, such as B. peoniae on peonies, B. squamosa on onion, and B. tulipae on tulips. These species of Botrytis share some common characteristics in pathology and ecology. The generic name Botrytis is derived from the Greek bótrys ("cluster of", "grapes") and the Latin suffix -itis ("like"). [5]
The anamorphs of Botryotinia are mostly included in the "imperfect fungi" genus Botrytis. The genus contains 22 species and one hybrid. The genus contains 22 species and one hybrid. Plant diseases caused by Botryotinia species appear primarily as blossom blights and fruit rots but also as leaf spots and bulb rots in the field and in stored ...
Ulocladium botrytis is a hyphomycetous mould that favors growth in damp indoor environments. [2] Although it mainly uses nitrogen, [11] [12] other nutrient sources have been tested to determine that U. botrytis growth rate is dependent on the type of media provided.
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".
There are seven different species of Botrytis associated with onions in storage, but the rot induced by B. allii and B. aclada causes the greatest commercial loss. The two can be distinguished microscopically; the conidia of B. allii have a maximum length of 15 μm and mean size of 10.2 × 5.7 μm, while the conidia of B. aclada have a maximum length of 12 μm and mean size of 8.6 × 4.6 μm.
Botrytis fabae is a plant pathogen, a fungus that causes chocolate spot disease of broad or fava bean plants, Vicia faba. It was described scientifically by Mexican-born Galician microbiologist Juan Rodríguez Sardiña in 1929.
Noble rot (French: pourriture noble; German: Edelfäule; Italian: Muffa nobile; Hungarian: Aszúsodás) is the beneficial form of a grey fungus, Botrytis cinerea, affecting wine grapes. [1] Infestation by Botrytis requires warm and humid conditions, typically around 20 degrees Celsius and above 80% humidity. [2]
Botrytis squamosa (teleomorph: Botryotinia squamosa) is a fungus that causes leaf blight on onion (often termed ‘blast’) that is distinctly characterized by the two stages – leaf spotting followed by blighting. [1] The pathogen is an ascomycete that belongs to the family Sclerotiniaceae in the order Helotiales. [2]
