Fate of aflatoxins and fumonisins during the processing of maize into food products in Benin by Fandohan, P., Zoumenou, D., Hounhouigan, Djidjoho J., Marasas, W.F.O., Wingfield, M.J., Hell, K.

“…The fate of aflatoxins and fumonisins, two mycotoxins that cooccur in maize, was studied through the traditional processing of naturally contaminated maize in mawe, makume, ogi, akassa, and owo, maize-based foods common in Benin, West Africa. Levels of total aflatoxin and fumonisin were measured at the main unit operations of processing, and the unit operations that induce significant reduction of mycotoxin level were identified. …”

Association of vertical rootpulling resistance with root lodging and grain yield in selected S1 maize lines derived from a tropical lowNitrogen population by Kamara, A.Y., Kling, J.G., Menkir, A., Ibikunle, O.

“…Root lodging and poor soil fertility are major constraints to maize production in the Guinea savannah of West Africa. Vertical root-pulling resistance is an indicator of the rooting characteristics of maize cultivars and could be used to select cultivars which have higher resistance to root lodging, take up nitrogen efficiently and have high yield. …”
