<i>Fusarium</i> spp. and fumonisin B₁ in stored maize from Ogun State, Nigeria

Abstract

Abstract A survey was conducted in 2000 to determine the incidence of Fusarium spp and fumonisin B 1 contamination in maize in farm stores in eight areas of Ogun State, Nigeria. F. moniliforme was the predominant species, in 56% of the samples, with a mean kernel infection of 68% in positive samples. The other species in decreasing order of abundance were F. graminearum, F. pallidoroseum, F. solani and F. oxysporum . Analysis by high performance liquid chromatography (HPLC) indicated that 51% of the samples were contaminated with fumonisin B 1 , at 65 to 1830µ g /kg. Copyright © 2003 Whurr Publishers Ltd
