Spodoptera litura (Noctuidae: Lepidoptera) is a notorious leaf damaging pest in Tamil Nadu in onion and responsible for considerable yield loss. A new biological insecticide spinetoram 12 SC was evaluated for effect on leaf damage due to S. litura on onion at field conditions during 2012 and 2013 kharif seasons. Spinetoram 12 SC was applied as foliar spray at 30, 36 and 45 g a.i. ha-1 and compared with emamectin benzoate 5 SG @ 11 g a.i. ha-1, spinosad 45 SC @ 78 g a.i. ha-1, fipronil 80 WG @ 40 g a.i. ha-1 and thiamethozam 25 WG @ 62.5 g a.i. ha-1. Results indicated that spinetoram 12 SC was significantly effective at 36 and 45 g a.i. ha-1 when sprayed thrice at 15 days interval in minimizing leaf damages on onion plants and in increasing the bulb yield. All the spinetoram doses did not show any phytotoxic symptoms on onion plants.
