Abstract
A field experiment was conducted during rainy season (kharif) 1993 and 1994 to find out an effective and economical insecticide for controll ing podborer (Helicoverpa armigera Hubner), plume moth (Marasmarcha li ophanes Mey) and podfly (Melanogromyza 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 - s eed - kernel suspension (NSKS) 3%, though gave 1 : 11.77 cost : benefi t ratio, was less effective and economical for controlling these insec ts.
