Abstract
Methods and compositions are provided for the control or prevention of aflatoxin contamination of agricultural commodities. Non-toxigenic strains of Aspergillus flavus are shown to inhibit aflatoxin production by toxigenic strains. Additionally, the non-toxigenic strains produce a factor in culture that alone inhibits aflatoxin production by toxigenic strains.
Claims2
A method for the control of prevention of aflatoxin contamination in agricultural commodities comprising:
- a) spraying or delivering to an agricultural commodity, soil and/or crop a non-toxigenic strain of Aspergillus flavus, which has been selected for its ability to inhibit aflatoxin producing strains of Aspergillus flavus, in an amount effective to inhibit subsequent aflatoxin production by toxigenic strains of Aspergillus flavus.
A method for the control or prevention of aflatoxin contamination in agricultural commodities comprising:
- a) spraying or delivering to an agricultural soil and/or crop an effective amount of a non-toxigenic strain of Aspergillus flavus sufficient to control or prevent subsequent contamination of commodities caused by aflatoxigenic strains of Aspergillus flavus present on that crop or on the soil.
