A field experiment was conducted at Entomology Farm, ICAR Research Complex for
North Eastern Hill Region, Umiam, Meghalaya to evaluate some botanicals and new
generation pesticides against pod borer complex in pigeon pea. Pigeon pea variety ‘Bahar’
was sown in 4m X 3m plot size at 60cm (R-R) X 30cm (P-P) spacing with three
replications. Infestation of A. clavipes and M. obtusa was significantly reduced in plots
treated with botanicals and chemical pesticides compared to control. Infestation of A.
clavipes and M. obtusa was significantly reduced in fipronil 5SC treated plots compared to
other treatments. Among botanicals, karanjin 2EC was found to be the most effective
treatment against A. clavipes; while pod fly damage was found minimum in neem oil
treated plots. Fipronil 5SC was found to be the best insecticides with lowest grain damage
and higher benefit cost
