An eco-friendly approach for management of aflatoxin contamination in chilli was undertaken by evaluating the genotypes, plant extracts and bioagents against Aspergillus flavus under in vitro condition. Thirty one genotypes were evaluated against aflatoxin producing fungi in chilli using pinprick inoculation. Genotypes viz., LCA-206, HTL, GOLI and H-9623 showed immune reaction, while JCA-283, AAUOC-24, KA-2 and INO-I0 showed resistant reaction. Besides, nine genotypes were moderately resistant and remaining ones were susceptible. A complete inhibition (100%) of A. flavus was observed in neem seed kernel extract (NSKE), nimbicidin and pongamia oil at 5 per cent. An indigenous Pseudomonas fluorescens bioagent isolate inhibited (74.9%) the growth of A. flavus followed by Trichodenna harzianum (70.4%).
