Abstract: To study crop phenology based management of pod borer complex of pigeonpea in four different cultivars in split plot design, two consecutive sprays of emamectin benzoate 5% SG @ 4.4 gm/10 liter water followed by flubendiamide 39.3% SC @ 3.9 ml/10 liter water at 15 days interval were taken at various crop growth stages. Four cultivars of pigeon pea viz., BDN-711 (early), BSMR-736 (late), BSMR-853 (late) and BSMR-716 (mid-late) were observed under field condition. The results revealed that in BDN-711 spraying at 50% bud formation stage was superior treatment where as in BSMR-736, BSMR-853 and BSMR-716 minimum incidence of H. armigera was recorded at flower initiation stage. The incidence of E. atomosa was recorded minimum, when the crop was sprayed at 50% flowering stage in all four cultivars.
