Ayalew, A.Kimanya, M.Matumba, L.Bandyopadhyay, RanajitMenkir, A.Cotty, P.[Controlling aflatoxins in maize in Africa: strategies, challenges and opportunities for improvement]Controlling aflatoxins in maize in Africa: strategies, challenges and opportunities for improvement

Aspergillus section Flavi have been implicated as causal agents of aflatoxin contamination in Africa. However, Aspergillus populations associated with aflatoxin contamination in Zambia have not been adequately detailed. Most of Zambia's arable land is non-cultivated and Aspergillus communities in...


Kachapulula, P.W.Akello, J.Bandyopadhyay, RanajitCotty, P.J.[Aspergillus section Flavi community structure in Zambia influences aflatoxin contamination of maize and groundnut]Aspergillus section Flavi community structure in Zambia influences aflatoxin contamination of maize and groundnut

Aflatoxin contamination in maize and groundnut is perennial in Ghana with substantial health and economic burden on the population. The present study examined for the first time the prevalence of aflatoxin contamination in maize and groundnut in major producing regions across three agroecological...


Agbetiameh, D.Ortega-Beltran, A.Awuah, R.T.Atehnkeng, J.Cotty, P.J.Bandyopadhyay, Ranajit[Prevalence of aflatoxin contamination in maize and groundnut in Ghana: population structure, distribution, and toxigenicity of the causal agents]Prevalence of aflatoxin contamination in maize and groundnut in Ghana: population structure, distribution, and toxigenicity of the causal agents

ompetitive exclusion of aflatoxin producers by endemic atoxigenic strains of Aspergillus flavus is a proventool for aflatoxin management being adapted for use in Africa. Field efficacy of an experimental formulationconsisting of four native atoxigenic strains (La3303, La3304, La3279 and Ka16127) ...


Atehnkeng, J.Ojiambo, P.Cotty, P.Bandyopadhyay, Ranajit[Field efficacy of a mixture of atoxigenic Aspergillus flavus Link: Fr vegetative compatibility groups in preventing aflatoxin contamination in maize (Zea mays L.)]Field efficacy of a mixture of atoxigenic Aspergillus flavus Link: Fr vegetative compatibility groups in preventing aflatoxin contamination in maize (Zea mays L.)

Aspergillus flavus is the most common causal agent of aflatoxin contamination of food and feed. However, aflatoxin-producing potential varies widely among A. flavus genotypes with many producing no aflatoxins. Some non-aflatoxigenic genotypes are used as biocontrol agents to prevent contamination...
