The present study was conducted to find out the bio-efficacy of different new molecules and botanicals against Hadda beetle, Henosapilachna vigintioctopunctata on brinjal during Rabi, 2017-18 at Research Farm, College of Agriculture, Swami Keshwanand Rajasthan Agricultural University, Bikaner. The evaluation of bioefficacy of nine new molecules and botanicals against Henosapilachna vigintioctopunctata revealed that the treatment spinosad (0.02%) proved to be most effective in reducing the pest population followed by indoxacarb (0.001%), emamectin benzoate (0.002%) and quinalphos (0.05%). Cartap hydrochloride (0.1%) and malathion (0.1%) were in moderate in efficacy. Khimp extract (5%) proved least effective followed by garlic extract (5%) and NSKE (5%). The decreasing order of efficacy of the tested chemicals was spinosad, indoxacarb, emamectin benzoate, quinalphos, cartap hydrochloride, malathion, NSKE, garlic extract and khimp extract.
