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

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

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

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.)

Crops frequently contaminated by aflatoxins are important sources of revenue and daily nourishment in manyportions of sub-Saharan Africa. In recent years, reports have associated aflatoxinswith diminished human healthand export opportunities in many African Nations. Aflatoxins are highly carcinog...


Probst, C.Bandyopadhyay, RanajitCotty, P.[Diversity of aflatoxinproducing fungi and their impact on food safety in subSaharan Africa]Diversity of aflatoxinproducing fungi and their impact on food safety in subSaharan Africa

Maize infected by aflatoxin-producing Aspergillus flavus may become contaminated with aflatoxins, and as a result, threaten human health, food security and farmers’ income in developing countries where maize is a staple. Environmental distribution and genetic diversity of A. flavus can influence ...


Atehnkeng, J.Donner, M.Ojiambo, P.S.Ikotun, B.Augusto, J.Cotty, P.Bandyopadhyay, Ranajit[Environmental distribution and genetic diversity of vegetative compatibility groups determine biocontrol strategies to mitigate aflatoxin contamination of maize by Aspergillus flavus]Environmental distribution and genetic diversity of vegetative compatibility groups determine biocontrol strategies to mitigate aflatoxin contamination of maize by Aspergillus flavus

Aspergillus flavus has two morphotypes, the S strain and the L strain, that differ in aflatoxin-producing ability and other characteristics. Fungal communities on maize dominated by the S strain of A. flavus have repeatedly been associated with acute aflatoxin poisonings in Kenya, where managemen...
