Agbetiameh, D.Ortega-Beltran, A.Awuah, R.T.Elzein, A.Atehnkeng, J.Cotty, P.J.Bandyopadhyay, Ranajit[Biological control of aflatoxins in maize and groundnut through use of aflasafe products developed for Ghana]Biological control of aflatoxins in maize and groundnut through use of aflasafe products developed for Ghana

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

Atehnkeng, J.Mutegi, D.Ortega-Beltran, A.Augusto, J.Akande, A.Senghor, L.A.Falade, T.Akello, J.Cotty, P.J.Bandyopadhyay, R.[Management of aflatoxins in maize and groundnuts in Kenya: a farmers' training manual]Management of aflatoxins in maize and groundnuts in Kenya: a farmers' training manual

This report documents the key activities that were carried under the AgResults Aflasafe Pilot Project during the 2018/ 2019 maize-growing season on the verification process to trigger premium payments for successfully harvested and aggregated Aflasafe™-treated maize.


IITAAkande, A.Bandyopadhyay, R.Ortega-Beltran, A.Falade, T.Okpachu, G.Shenge, K.Cotty, P.[The AgResults Nigeria Aflasafe TM Challenge Project: 2019 Annual Report]The AgResults Nigeria Aflasafe TM Challenge Project: 2019 Annual Report

Maize is an important staple crop for the majority of the population in Uganda. However, in tropical and subtropical climates, maize is frequently contaminated with aflatoxins, a group of cancer-causing and immuno-suppressive mycotoxins produced by Aspergillus section Flavi fungi. In Uganda, ther...


Sserumaga, J.P.Ortega-Beltran, A.Wagacha, J.M.Mutegi, C.K.Bandyopadhyay, R.[Aflatoxin-producing fungi associated with pre-harvest maize contamination in Uganda]Aflatoxin-producing fungi associated with pre-harvest maize contamination in Uganda

In sub-Saharan Africa (SSA), diverse fungi belonging to Aspergillus section Flavi frequently contaminate staple crops with aflatoxins. Aflatoxins negatively impact health, income, trade, food security, and development sectors. Aspergillus flavus is the most common causal agent of contamination. H...


Bandyopadhyay, R.Atehnkeng, J.Ortega-Beltran, A.Akande, A.Falade, T.D.O.Cotty, P.["Ground-truthing" efficacy of biological control for aflatoxin mitigation in farmers' fields in Nigeria: from field trials to commercial usage, a 10-year study]"Ground-truthing" efficacy of biological control for aflatoxin mitigation in farmers' fields in Nigeria: from field trials to commercial usage, a 10-year study

Across sub-Saharan Africa, chili peppers are fundamental ingredients of many traditional dishes. However, chili peppers may contain unsafe aflatoxin concentrations produced by Aspergillus section Flavi fungi. Aflatoxin levels were determined in chili peppers from three states in Nigeria. A total ...


Ezekiel, C.N.Ortega-Beltran, A.Oyedeji, E.O.Atehnkeng, J.Kössler, P.Tairu, F.Hoeschle-Zeledon, I.Karlovsky, P.Cotty, P.J.Bandyopadhyay, R.[Aflatoxin in chili peppers in Nigeria: extent of contamination and control using atoxigenic aspergillus flavus genotypes as biocontrol agents]Aflatoxin in chili peppers in Nigeria: extent of contamination and control using atoxigenic aspergillus flavus genotypes as biocontrol agents

Increasing knowledge of the deleterious health and economic impacts of aflatoxin in crop commodities has stimulated global interest in aflatoxin mitigation. Current evidence of the incidence of Aspergillus flavus isolates belonging to vegetative compatibility groups (VCGs) lacking the ability to ...


Agbetiameh, D.Ortega-Beltran, A.Awuah, R.T.Atehnkeng, J.Islam, M.S.Callicott, K.A.Cotty, P.J.Bandyopadhyay, R.[Potential of atoxigenic Aspergillus flavus vegetative compatibility groups associated with maize and groundnut in Ghana as biocontrol agents for aflatoxin management]Potential of atoxigenic Aspergillus flavus vegetative compatibility groups associated with maize and groundnut in Ghana as biocontrol agents for aflatoxin management

Interactions between pathogenic and nonpathogenic fungal species in the tree canopy are complex and can determine if disease will manifest in the plant and in other organisms such as honey bees. Seasonal dynamics of fungi were studied in an almond orchard in California where experimental release ...


Ortega-Beltran, A.Moral, J.Puckett, R.D.Morgan, D.P.Cotty, P.Michailides, T.[Fungal communities associated with almond throughout crop development: implications for aflatoxin biocontrol management in California]Fungal communities associated with almond throughout crop development: implications for aflatoxin biocontrol management in California

To identify predominant isolates for potential use as biocontrol agents, Aspergillus flavus isolates collected from soils of almond, pistachio and fig orchard in the Central Valley of California were tested for their membership to 16 atoxigenic vegetative compatibility groups (VCGs), including YV...


Picot, A.Doster, M.Islam, M.Callicott, K.Ortega-Beltran, A.Cotty, P.Michailides, T.[Distribution and incidence of atoxigenic Aspergillus flavus VCG in tree crop orchards in California: a strategy for identifying potential antagonists, the example of almonds]Distribution and incidence of atoxigenic Aspergillus flavus VCG in tree crop orchards in California: a strategy for identifying potential antagonists, the example of almonds
