Excerpt
Introduction: 1. Fumonisins are a group of structurally related mycotoxins produced by a number of morphologically related Fusarium species (Fusarium moniliforme, F. proliferatum, F. napiforme, F. anthophilum, F. dlamini, F. nygamai, F. thapsinum and F. globosum) that can occur worldwide and can produce these toxins up to several g/kg on sterilized maize. Fusarium moniliforme [= F. verticillioides (Sacc.) Nirenberg] and F. proliferatum are amongst the most common fungi associated with maize and they can be recovered from most maize kernels including those that appear healthy. The formation of fumonisins in maize in the field is positively correlated with the occurrence of these two fungal species which are predominant during the late maturity stage. These species can cause Fusarium kernel rot of maize which is one of the most important ear diseases in hot maize-growing areas and is associated with warm, dry years and/or insect damage. Ears infected by F. graminearum (a nonproducing fumonisin maize pathogen) may be predisposed to F. moniliforme infection and fumonisin accumulation. In maize ears inoculated in the field with F. moniliforme or F. proliferatum one week after silk emergence, fumonisins accumulated in the visibly damaged (mouldy) kernels; in the case of F. proliferatum other toxins, i.e. beauvericin and fusaproliferin, were also produced by the same fungal strain.
