Pigeonpea (Cajanus cajan L. (Millsp.)) is a protein rich tropical grain legume mainly grown in India. It is attacked by more than 300 species of insects. Indiscriminate use of insecticides has lead to development of resistance and resurgence of insect pests along with environmental population. Hence the present study was conducted during Kharif, 2017-18 to find out the efficacy of certain indigenous products against pod borers in pigeonpea revealed that recommended insecticidal schedule (RIS) i.e., spraying of neem formulation 1500 ppm @ 5ml/l at 50% flowering, followed by chlorantraniliprole @ 0.3ml/l and flubendiamide @ 0.2 ml/l at 15 days interval, followed by chemical check (chlorpyriphos 20 EC @ 250 g a.i/ha) have recorded less pod damage due to pod borer complex (4.3 and 6.8%, respectively) with highest yield (1958 and 1588 kg/ha, respectively), highest net returns (Rs. 49012/- and 33182/-, respectively) and highest incremental cost benefit ratio (ICBR) (7.04 and 12.64, respectively) over all other treatments. Among different indigenous products, product 3 (Agniastra), followed by 2 (Brahmastra), 4 and 1 (Neemastra) respectively recorded net returns of Rs. 20907/-, 20744/-, 18096/- and 13368/-. However, the product 4, followed by 2, 3 and 1 respectively recorded ICBR of 2.84, 2.51, 2.36, and 2.05. The organic check i.e., NSKE 5% registered net returns of Rs. 18185/- with ICBR of 3.46. Further, it was also found that there was no significant difference between the treatments with regard to yield attributes viz., plant height, no. of primary and secondary branches, no. of pods/plant, no. of seeds/ pod and test weight.
