Biocontrol of Aspergillus flavus using inoculated bioplastic granules has been proven to be effective under
laboratory and field conditions. In the present study, the use of low-density pellets from recycled bioplastic
as a biocontrol strain carrier was evaluated. Applying recycled bioplastic pellets inoculated with
biocontrol A. flavus NRRL 30797 to two soils with different levels of indigenous A. flavus, resulted in a
rapid 55% and 63% decrease in percent aflatoxigenicity in A. flavus isolates from low and high population
soils, respectively. The decrease was significantly more rapid using lower-density recycled bioplastic
pellets than using higher-density bioplastic granules, but aflatoxin production by indigenous soil A. flavus
decreased to comparable levels in two months. A sprayable bioplastic formulation prepared from
inoculated recycled bioplastic pellets was effective in delivering adherent biocontrol A. flavus to corn
leaves, and in promoting a 4-fold increase in recovered non-aflatoxigenic A. flavus DNA one week later.
