Field experiment was conducted during kharif 2016-17 to study the efficacy of the botanicals and organic products viz., Azadiractin 0.15 EC @ 3 ml/L, Melia formulation 5 EC @ 3ml/L, Eupatorium formulation 5 EC @ 3m/L, three organic products viz., fermented buttermilk @ 50 ml/L, cow urine @ 100 ml/L and panchagavya @ 100 ml/L along with a synthetic insecticide, cypermethrin 25 EC @ 0.4 ml/L and their effect on fruit yield of okra against blister beetle, Mylabris spp. at Palampur, Himachal Pradesh. It was found that chemical insecticide proved to be significantly superior and most efficacious treatment in reducing the beetle population by 74.86 per cent and resulted in 16.58 per cent increase in the fruit yield. Azadiractin, Melia, Eupatorium and organic products were found to be moderately effective with 43.64 to 59.68 per cent population reduction. Cow urine and fermented buttermilk were found to be least effective and also resulted in least amount of increase in the fruit yield of 6.57 and 6.33 per cent.
