Abstract:

Aflatoxins are potent carcinogenic and mutagenic metabolites mainly produced by Aspergillus flavus. A study was conducted to manage the aflatoxin production in maize grains in ambient storage conditions using bioagents i.e., Trichoderma asperellm, T. viride and Aspergillus niger isolated from maize grain itself and initially tested for antagonistic ability against radial growth of Aspergillus flavus. T. asperellum was found most effective in suppressing the growth of test fungi. Inhibitory effect of these antagonists on aflatoxin production in ambient storage conditions was also studied on maize cultivars HQPM-1, HM-4 and Bio- 9681 under artificially inoculated condition. The formulation of T. asperellum @8gm/kg of grains was found most effective for 100% reduction in aflatoxin build up in cultivar HQPM-1, 96.32% in HM-4 and 93.04% in Bio-9681 after 4 month storage period.
