CHIMBEKUJWO, I. B.. Frequency and pathogenicity of fusarium wilts (Fusarium solani and Fusarium equiseti) of cotton (Gossypium hirsutum) in Adamawa in Nigeria. Rev. biol. trop [online]. 2000, vol.48, n.1, pp.01-05. ISSN 0034-7744.

Cotton fungi were surveyed in Ngurore, Adamawa, Nigeria in 1992 and 1993 by counting the number of isolates in each 100 infested plants per plot. Approximately 90% of the isolated fungi were Fusarium solani and Fusarium equiseti, both pathogenic; F. solani isolates were more virulent and frequent than F. equiseti. The high frequency and virulence of both fungi make them important pathogens of cotton in the area.
