Subject Groundnut
 
Description Groundnut is a premier oilseed crop of worldgrown in tropical and subtropical climatic
conditions. Among all the diseases affecting the groundnut, aflatoxin contamination is most
concern as it affects the quality of the produce and thereby limiting the trade in International
market. The efficacy biocontrol agents and natural products and reaction of different cultivars,
germplasm and advanced breeding lines were tested in vitro. Among the biocontrol agents
T.harzianum (IOF) was found best. Among the nine natural products the nimbicidin showed
maximum inhibition of A.jlavus at all the concentrations (1, 5 and 10 per cent). Among the 10
cultivars, 34 germplasm and 25 advanced breeding lines,six weremoderately resistant, twenty
one were susceptible and fourty seven were highly susceptible in spore spray method while in
pin prick method only one (ICGV02266) showed the moderate resistance while remaining
found highly susceptible. ICGV 02266 showed both seed coat and cotyledon resistance.
Various eco-friendly approaches for management of Aspergillus flavus an Aflatoxin producing
fungi in groundnut are discussed.
