Description Groundnut seeds are prone to quality deterioration and damage due to improper storage. Hermetic
storage of pods offers a novel, sustainable and ecologically safe alternative over traditional methods. In
this paper, we demonstrate the efficacy of triple-layer “Purdue Improved Crop Storage (PICS)” bags, (that
comprises of two inner high density polyethylene bags and one outer woven polypropylene bag), for
protecting pods from quality deterioration, damage by bruchids (Caryedon serratus) and aflatoxin
contamination (Aspergillus flavus). Custom made triple-layer bags were used and pods (of cv ICGV 91114)
were placed @ 2 kg/bag. Over four months of storage under ambient conditions, triple-layer bags supported
retention of seed weight, germinability and oil content significantly better than cloth bags.
Further, under both natural and artificial infestations with A. flavus, seed aflatoxins levels were lower in
PICS bags compared to cloth bags. Toxin accumulation in PICS bags deliberately infested with bruchids
and A. flavus was less compared to cloth bags under similar conditions. Bruchid damage to pods was less
in PICS bags versus cloth bags in all cases. Our results suggest the superiority of triple-layer PICS bags
over cloth bags in protecting seed viability, seed weight and oil content while safeguarding the
groundnuts from bruchids and retarding toxin accumulation.
