Occurrence of broad bean (Vicia faba L.) diseases in Olsztyn-Elbąg and Bydgoszcz Provinces
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 <i>Cercospora</i> and <i>Botrytis</i>, 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 <i>Fusarium family</i> (ca. 70%). The prevailing species were <i>Fusarium oxysporum</i>, next <i>F. solani</i> and more rarely <i>F. culmorum</i> and <i>F. avenaceum</i>. Climate conditions and soil species affected considerably the species composition of the root fungi.
