Cabbage Pathogens, Their Distribution, Harmfulness And Control
Santrauka [EN]

The experiment were carried out in the Plant protection laboratory of Lithuanian institute of horticulture (since 2010 Institute of horticulture, LRCAF) and CJ-SC "Sodziaus rytas" Pasvalys district in 2008–2010. The aim of research was to investigate the pathogens, their prevalence and effectiveness of protection measures to reduce losses of white cabbage.

From the surface of stored white cabbage tissue identified 14 species of fungi belonging to Alternaria, Botrytis, Cladosporium, Fusarium, Penicillium, Phoma genera. The most of them are pathogenic.

White cabbage during the growing season was mostly damaged alternaria disease (from 3.12 to 40.1%), grey mould (1.04 to 5.21%) and black rot (1.04 to 68.75%). The most susceptible were 'Qualitor' F1 'Sulej' F1 'Nordpol' F1 cabbage. The investigations of the morphological features revealed that dark leaf spot (Alternaria spp.), gray mould (Botrytis cinerea) and soft bacterial rots (Erwinia spp, Pseudomonas spp.) are the most harmful diseases during storage.

Obtained data revealed that applications with fungicides Amistar 250 SC (azoxystrobine) 0.8 l ha-1, Signum 334 WG (boskalid, pyraclostrobine) 1.0 kg ha-1, Folicur 250 EW (tebuconazole) 1.0 l ha-1 and Rovral Aqua Flo (iprodione) 1.0 l ha-1 on second part of plant vegetation reduced lesions of rots in ‘Kingston’F1, ‘Lenox’F1 and ‘Paradox’F1 cabbages during storage up 54.9–82.0 %.
