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, Fusarium equiseti, Fusarium oxysporum and Fusarium poae. Pathogenicity tests under artificial infection conditions showed Fusarium oxysporum (isolate S/l) to be the most pathogenic among of the four investigated species. The other species proved much less pathogenic.
