Online published on 28 March, 2024. Abstract Groundnut seed has the highest quality deterioration due to indigenous techniques and damage due to Bruchid infestation and mold growth. Purdue Improved Crop Storage (PICS) bags (T1) were introduced for hermetic storage of groundnut pods against traditional methods using gunny bags (T2). PICS storage bags were consisting of 80 micron thick high density polyethylene in two inner layers and surrounded by a third layer of woven nylon bag for strength. For the assessment of PICS hermatic storage bags to reduce the pest incidence, Groundnut varieties (Dharani and Kadiri 6) were selected and stored for 6 months period. T1 consisted of Groundnut varieties with good germination percent during the storage study. T2 consisted of Groundnut varieties with a loss in germination per cent of 20 and 26 under the indigenous method of using gunny bags whereas in PICS (T1) negligible loss of 2 and 4% were recorded during 180 days. Grain weight of samples stored in PICS bags (T1) was restored from the beginning to end of the study of 6 months and maintained ‘A’ grade quality up to the 5th months where in T2, the loss of grain weight was higher and the quality of grain was reached to ‘D’ grade at the end of the study. Thus, the efficacy of triple-layer PICS bags over gunny bags was protecting seed viability, seed weight and quality content while safeguarding the groundnuts from bruchids and retarding toxic aggregation.
