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]
Botrytis Leaf Blight (Botrytis squamosa) is a fungal disease which mainly affects plants in the allium family, particularly onions. [14] [15] The impacts of Botrytis Leaf Blight are mainly seen in the leaves of the plant.
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.
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]
Leaf blight occurs in areas with hot and humid weather. The spores land on onion leaves, penetrate the skin, and rapidly kill the leaf. This causes a severe reduction in bulb size, as high as 50%, and can happen in less than a week. [120] Applications of foliar fungicides can be used to control leaf blight.
