different African countries use exotic non toxic aspergillus flavus as biocontrol in controlling aflatoxin. Am worried on the effectiveness of it in long run considering sensitivity of fungi to temperature and humidity. native toxic aspergillus flavus can be more strong to the stage of outcompeting exotic atoxigenic one considering the toxic one is born there?
Indeed one must be aware of using this atoxigenic Aspergillus biocontrol. It seems it will need to be applied often. Here is an article taking this into account : Non-aflatoxigenic Aspergillus flavus to prevent aflatoxin contamination in crops: advantages and limitations (nih.gov)
I think Aflasafe- biocontrol product being used in Africa, doesn't have any exotic strain. It contains 4 atoxigenic strains predominantly found in Africa
