Abstract

A field expeliment was conducted during rainy season (kharif) 1993 and 1994 to find out an effective and economical
insecticide for controlling podborer (Helicoverpa armigera Hubner), plume moth (Marasmarcha liophanes Mey) and
podfly (Melanagromyza obtusa Malloch) on vegetable - purpose pigeonpea [Cajanus cajan (L.) Millsp.]. Endosulfan Ec
0.035% (1: 14.18) gave the highest incremental cost: benefit ratio, followed by endosulfan WP 0.035% (1 : 12.95) and
chlorpyriphos 0.02%. Neem - seed - kernel suspension (NSKS) 3%, though gave 1 : 11.77 cost: benefit ratio, was less
effective and economical for controlling these insects
