An experiment was conducted for three consecutive years from 2016 to 2018 during Rabi season at Horticulture Research and Extension Center, Hassan, Karnataka. A study was conducted by using Complete Block Design with four replications under storage. For PTM management studies, Kufri Jyoti tubers were planted at 60 cm X 20 cm spacing with soil application of recommended dose of fertilizers (75:75:100 kg NPK/ha) and FYM (25 t/ha) during Kharif season as per package of practices. After harvesting of Kharif season crop, tubers were dipped with neem oil and Bt formulations at different concentrations were evaluated. The per cent incidence of tuber damage due to PTM was documented at monthly intervals for four months under room temperature conditions. The pooled data of three years indicated that, out of five treatments Bt formulation @ 2 per cent concentration noticed lowest per cent mean incidence of tuber damage of 24.05 followed by Bt formulation @ 1 per cent concentration was revealed 29.30 per cent mean incidence of tuber damage. Hence, dip treatment of tubers with Bt formulation @ 2 per cent was found to be effective for post harvest management through biological control of potato tuber moth damage under storage in Southern Dry Zone of Karnataka in India.
