| Abstract: | Pre- and post harvest aflatoxin contamination of groundnut caused by Aspergillus flavus is a major problem in the semi-arid tropics. Fluorescent Pseudomonas, Bacillus and Trichoderma spp. potentially antagonistic to A. flavus were isolated from the geocarposphere (pod-zone) of groundnut and used successfully for the control of pre-harvest groundnut seed infection by A. flavus. In greenhouse and field experiments, inoculation of selected antagonistic strains on groundnut resulted in significant reduction of seed infection by A. flavus, and it also reduced >50% of the A. flavus populations (as cfu) in the geocarposphere of groundnut. |
