Abstract:
Data collected from replication sites and processed, it has been revealed that treatment T2 i.e. installation of H. armigera pheromone traps @ 10 traps / ha unable to manage the H.armigera population. Traps are source of monitoring .There was a big challenge for the researcher to enhance the yield of pigeon pea because H. armigera is a cosmopolitan & poly phagou in nature. Caring a research at farmer’s field is also a big task because most of farmers are marginal in nature and their lands are not suitable for growing pigeon pea in Sheohar district of Bihar. Among other treatments, T4 i.e. Spraying of Profenophos 50% EC @ 2ml/L water after 25% of pod stage and second spray after 15 days with Indoxacarb14.5% SC @ 0.3 ml/L water showed better results over other treatments. A minimum number of damaged pods and shriveled grains have been recorded in treatment T4 and yielded a maximum (20.18 q/ha). Analysis shows a significant difference over the check.T4 i.e. Spraying of Profenophos 50% EC @ 2ml/L water after 25% of pod stage and second spray after 15 days with Indoxacarb14.5% SC @ 0.3 ml/L water is recommended for pod borer management in pigeon pea. Tunneling in Pods, the larval population in pods, caterpillar destroying buds, flowers, pods and reduction in yield was maximum in treatment T1.
