Występowanie chorób bobiku (Vicia faba L.) w rejonach olsztyńsko-elbląskim i bydgoskim [Occurrence of broad bean (Vicia faba L.) diseases in Olsztyn-Elbąg and Bydgoszcz Provinces]

Abstract

During the years 1981–1985, there were conducted studies of the healthiness of broad bean,'Nadwiślański' variety, cultivated in different soil and climate conditions of the two regions: i.e. Bydgoszcz – comparatively warmer and drier, and Olsztyn-Elbląg – colder and moister. It was found that the main reason for a premature broad bean leaves dry in up in the Olsztyn-Elbląg Region was caused by the fungi Cercospora and Botrytis, and in the Bydgoszcz Region – the root rot which occurs here to a greater extent. Root gangrene was greater intensity in drier and lighter soils. Rotting broad bean roots were most frequently occupied by the fungi of the Fusarium family (ca. 70%). The prevailing species were Fusarium oxysporum, next F. solani and more rarely F. culmorum and F. avenaceum. Climate conditions and soil species affected considerably the species composition of the root fungi.
