Abstract:
Investigations were carried out on Studies on “Bio-efficacy of botanicals on Chickpea Pod Borer (Helicoverpa Armigera Hubner) under Bundelkhand region of Jhansi’’ was carried out at the Experimental, Organic Research farm Kargunwa Ji Jhansi, Institute of Agricultural Sciences, Department of Entomology, Bundelkhand University Jhansi (Uttar Pradesh) during Rabi season of 2020-2021. During the course of investigation the present investigation was undertaken to find out suitable and low cost substitute for the management of Helicoverpa armigera (Hubner) on chickpea by using botanicals. The field trial was laid out in (RBD) design with three replications and nine treatments including control (water spray). The observations were recorded on average per cent pod damage caused by Helicoverpa armigera (Hubner) Mean number of chickpea pod borer per plant minimum was significantly recorded in (1.237, 1.210 and 1.020) in plot Nerium indicum at 0.05% foliar spray. Minimum pupal width was minimum in Nerium indicum (3.997) mm. in T₆ plot. Total development period of Pod borer (Helicoverpa. armigera) minimum (1.913) days of egg period in rose, while minimum (17.687) days of larval period in T₁ plot chickpea, minimum pre-pupal days (2.913) days of in T₁ plot chickpea. Minimum pupal days (14.597) days of pupal period in T₇ Nerium indicum. Total development (32.100) days of total development period in T₇ plot Nerium indicum. The highest grain yield was recorded (20.990) q/ha with T₇ Nerium indicum (0.05%) while lowest was (12.233) q/ha recorded in control T₀ plot.
