ABSTRACT: A field experiment was carried out to find out relative efficacy of spray schedules of six insecticides and Multineem along with Multineem alone against Helicoverpa armigera (Hubner) in pigeon pea. The minimum pod damage (13.67 and 9.33%) was recorded in spray schedule of Multineem followed by Endosulfan with highest grain yield (17.36 and 19.19 q haG<SUP>1</SUP>) and the maximum (26.00 and 25.33%) in spray of Multineem alone with lowest grain yield (13.59 and 13.67 q haG<SUP>1</SUP>) as compare to control, pod damage (28.67 and 37.00%) and yield (10.27 and 10.00 q haG<SUP>1</SUP>) in two successive years 2004 and 2005, respectively. Among all spray schedules, the foliar spray of Multineem (0.5%) at 50% flowering stage followed by Endosulfan (0.07%) after 15 days of first spray given relatively excellent performance for the management of pod borer in pigeon pea.
