Frequency and pathogenicity of fusarium wilts (<i>Fusarium solani</i> and <i>Fusarium equiseti</i>) of cotton (<i>Gossypium hirsutum</i>) in Adamawa in Nigeria

Resumen

Cotton fungi Were surveyed in Ngurore, Adamawa, Nigeria in 1992 and 1993 by counting the number of isolates in each 100 infested p1ants per p1ot. Approximately 90% of the isolated fungi were Fusarium solan; and Fusarium equiseti, both pathogenic; F. solani isolates were more virulent and frequent than F. equiseti. The high frequency and virulence of both fungí make them important pathogens of cotton in the area.
