Bio-competitive exclusion: efficacy of non-aflatoxigenic Aspergillus section Flavi-L morphotypes in control of aflatoxigenic Aspergillus flavus in groundnuts (Arachis hypogaea L.)

Abstract Background The biological control mechanism of Aspergillus flavus (aflatoxigenic) strains in groundnuts with atoxigenic from the same species through competitive exclusion employed use endemic and well-adapted within agro-ecological zones Zimbabwe. selected elite non-aflatoxigenic isolates A. native to Zimbabwe were evaluated for their capability reduce aflatoxin contamination under laboratory conditions. Results Average reduction percentages B concentration 2019 2020 set experiments ranged 91.6 ± 3.4 95.8 3.1% 90.29 3.6% 95.29 4.1%, respectively. Levels co-inoculation research administered significantly reduced all experimental units carried out. Treatment efficiencies tested this study at 4:1 2:1 1.20 2.52 1.02 1.21, efficacy against aflatoxigenic strain (ZMW 0127) indicates that flavus. have sound practical applications vast communities aflatoxin-producing fungi across Conclusion recognized will be an incentive as dynamic active ingredients biocontrol formulations decrease aflatoxins grown
