Saprophytic and parasytic micomycetes on sugar beet (Beta vulgaris L.)

Abstract

The aims of this study was to isolate and identify all micromycetes genera developed on Libero sugar beet variety during the field trial localized on south region from Moldavian plain (Ezareni Farm Resort at the University of Agricultural Sciens and Veterinary Medicine “Ion Ionescu de la Brad”, Iasi) and, also from five seed varieties of sugar beet (Libero, Merak, Victor, Barsa, Brasov) during germination using ”Blotter method”. The“blotter method” is one of the incubation methods where seeds are incubated usually for 7 days at 22˚C. After incubation, fungi developed on each seed are examined under different magnification of a stereomicroscope and identified. During the laboratory analysis 8 genera of micromycetes (Sclerotinia, Botrytis, Fusarium, Alternaria, Penicillium, Cladosporium, Volutella, Trichotecium) were isolated and identified. Volutella sp. and Trichotecium sp. are reported for the first time on sugar beet in Romania.
