Effect of spinetoram 12 SC, alone and in combination with quinalphos 25 EC 350 g a.i./ha, carbendazim 50 WP 125g a.i./ha and urea (2%) was studied on Maruca vitrata under field conditions during 2012–2013 and 2013–2014 in kharif seasons. The results showed that Spinetoram 12 SC 45 g alone and in combination with quinalphos 25 EC 350 g a.i./ha, carbendazim 50 WP 125 g a.i./ha and urea (2%) were significantly effective in minimizing M. vitrata, when sprayed thrice at 15 days interval and increased grain yield. Spinetoram 12 SC 45 g alone and in combination with quinalphos 25 EC 350 g a.i./ha, carbendazim 50 WP 125 g a.i./ha and urea (2%) did not showed phytotoxic symptoms on pigeonpea plants.
