Dataset: Efficacy of Biopesticides in Management of Potato Tuber Moth, Phthorimaea operculella (Zeller), in Three Different Cultivars of Potato under Storage

Pest infestation causes heavy loss to farmers; both in fields and in stores. The study evaluated the efficacy of biopesticides in management of potato tuber moths (PTM) under storage condition. The potato cultivars Khumal Seto-1, Janak Dev and MS-42.3 and biopesticides <em>Bacillus thuringiensis</em>, <em>Acorus calamus</em>, <em>Azadirachta indica</em>, <em>Artemisia vulgaris</em> and a control were used. The cv. Janak Dev had the lowest infestation points per tuber (8.13), emergence of PTM adults (19.77%), physiological loss in weight (26.03%), decay loss (17.89%) and tuber damage score (2.74). The biopesticide <em>Acorus calamus</em> had the least infestation points per tuber (2.56), infested eyes per tuber (0.17), emergence of PTM adults (1%), tuber damage index (2.24), physiological loss in weight (12.11%), decay loss (4%) and tuber damage score (1.36). <em>Acorus calamus</em> had reduced larval mining by 88% and eventually had reduced decay loss by 93% as compared to control. The parameters relating to damage indicated that the cv. Janak Dev was least susceptible among the tested cultivars and <em>Acorus calamus</em> provided the best protection against damage caused by potato tuber moth.
