  Aqueous extract of individual and mixed form of Azadirachta indica A. Juss seeds kernel and leaves of Milletia ferruginea, Hochst and Croton macrostachyus Hochst was tested against African bollworm, Helicoverpa armigera Hubner. Antifeedant activity of selected plant extract was tested at 1%, 2.5%, 5% and 10% concentration against 4th instar larvae of H. armigera in the laboratory and 5% concentration was tested under field condition. All the tested plant extract showed 100% protection at 5% and 10% concentration. Among the various botanical treatment Neem Seed Kernel Extract (NSKE) and NSKE+BLE (Birbira Leaves Extract) was effective at 2.5% concentration with minimum pod damage. In the field observation among the botanicals, reduction of larval population in the treatment of NSKE, BLE and NSKE+BLE was statistically not significant (p>0.05; LSD). The lowest percentage pod damage (0... View More»
