BOTRYTIS CINEREA EN VID PDF

Get e-Alerts Abstract Botrytis cinerea, gray mold is one of the most notorious phytopathgen, causing serious economic loss in agricultural industry. Their phytotoxic effects are mainly derived from secreted virulence proteins and terpenoid-type secondary metabolites. Azole fungicides are commonly used to manage the disease. However, their biochemical effects other than sterol biosynthesis were not documented, especially toxic secreted metabolites.

Graufäule – Botrytis cinerea

It is particularly dangerous in glasshouses, for it is here that it finds environmental conditions which favour its development. Cyclamen flower buds are highly susceptible. They are of the Moniliaceae family, and are septate fungi: their mycelium is divided by partitions. The reproductive apparatus consists of asci, bag-like cells enclosing spores known as ascospores. The asci are themselves enclosed in an ascocarp, making these fungi Euascomycetes Higher Ascomycetes. The sexual form is not so common and harder to find.

By Susan Jones Take Precautions Now To Prevent This Fungus from Marring Winter Flowers A fungal disease affecting many different types of herbaceous and woody plants, botrytis strikes during cool, damp weather in areas where air circulation is poor. On orchids, the disease, caused by Botrytis cinerea, causes unsightly brown spotting of blooms. The fungus most often affects Phalaenopsis and Cattleyas, but may be found in a wide range of orchid genera. Older flowers are highly susceptible to infection.
