An experiment was carried out to know the effect of seed treatment with plant products and deltamethrin on storability of wheat seeds at University of Agricultural Sciences, Dharwad. The results revealed that, the botanicals and deltamethrin seed treatments were significantly superior in controlling the storage insect and maintaining higher seed quality throughout the storage when compared to untreated control. Among the botanicals, the sweet flag rhizome powder @ 10.0 g / kg of seed found better by recording significantly higher germination percentage (87.00%), vigour index (2694) and dry weight of seedlings (329.50 mg) and lower electrical conductivity (0.488 dSm-1) and insect infestation (3.33%) compared to untreated control (77.31 %, 2265, 326.67 mg, 0.540 dSm-1, 32.67% respectively) at the end of 10th month of storage.
