ABSTRACT Relative efficacy of various botanicals and biopesticides against major insect pests on brinjal was evaluated under field conditions during rabi 2018-2019. The results showed that two applications of neem + pungam oil @ 20 ml/ l was significantly the most effective with reduction of sucking pests (leaf hopper, 70.20%; aphid, 60.54%; whitefly, 72.49%). Ginger + garlic rhizome extract @20 ml/ l was observed to be the next best. Shoot and fruit borer damage reduction was also maximum in neem + pungam oil treatment with 66.97% shoot and 64.16% fruit damage followed by ginger + garlic rhizome extract with 61.57% shoot and 56.32% fruit damage. Neem + pungam oil led to maximum yield of 12.25 t/ha, followed by ginger + garlic rhizome extract (11.06 t/ ha).
