Field experiment conducted at Regional Agricultural Research Station (RARS), Lam, Guntur during Kharif, 2018 with an aim to evaluate the efficacy of eco-friendly products against Helicoverpa armigera and Maruca vitrata revealed that spinosad 45% SC @ 73 g a.i/ha (grams of active ingredient per hectare), followed by NSKE @ 5% were found effective with less no. of larvae and there by less pod and seed damage. Thus, spinosad 45% SC @ 73 g a.i/ha has recorded 92.4% and 92.8% reduction of larval population and 83.85 and 78.6% reduction of pod damage due to of H. armigera and M. vitrata, respectively over control. Whereas, NSKE 5% respectively recorded 70.8% and 75.8% reduction of larval population and 64.8% and 61.9% reduction of pod damage over control. Further, higher grain yield with highest incremental cost benefit ratio (ICBR) was recorded in spinosad 45% SC (1640kg/ha and 6.59, respectively), followed by NSKE 5% (973 kg/ha and 6.52, respectively).
