Abstract
The paper describes the symptoms of the Fusarium wilt and necrosis of root and lower stem of soybean, which include leaf chlorosis, wilt of the apical portion of the plant, necrosis of the root and lower stem, and wilting of the whole plant. The pods are often poorly developed. The seeds may be smaller and lighter in the weight and infected, as well. Isolated from diseased soybean plants were the species Fusarium avenaceum, F. equiseti, F. oxysporum and F. poae. Pathogenicity tests under artificial infection conditions showed F. oxysporum (isolate S/1) to be the most pathogenic among of the four investigated species. The other species proved much less pathogenic.Fuzariozna uvelost, nekroza korena i prizemnog dela stabla soje pojedinih godina se javlja i u nasoj zemlji u vecoj ili manjoj meri. Ovo oboljenje se intenzivnije javlja u godinama sa toplim i suvim letima, pogodnim za razvoj uvelosti soje, prouzrokovane vrstama iz roda Fusarium. Iz uzoraka obolelih biljaka sa simptomima oboljenja su izolovane i determinisane vrste Fusarium avenaceum, F. equiseti, F. oxysporum i F. poae. U ogledima sa vestackom inokulacijom soje najvecu patogenost ispoljavao je izolat S/1 F. oxysporum. F. oxysporum (S/1) je znacajno smanjio klijavost i nicanje biljaka soje, a povecao broj trulih zrna. Ostale vrste ispoljile su znatno slabiju patogenost. Problemu fuzariozne uvelosti, nekroze korena i prizemnog dela stabla soje trebalo bi posvetiti vecu paznju zbog mogucnosti uvecanja znacaja ovog oboljenja usled sve cesce pojave toplih i suvih leta, povoljnih za razvoj bolesti.
