(Ag) Entomology Major: Entomology Department: Entomology Advisor: Dr. Gaje Singh Thesis Title: “Evaluation of Indigenous plant extracts against Gram Pod borer, Helicoverpa armigera (Hubner) and Spotted pod borer, Maruca vitrata (Geyer) in black gram (Vigna mungo)” The present investigation was performed at CRC, SVPUA&T Meerut 250110 (UP), during Kharif 2022 in RBD design with 3 replication and seven treatments to evaluate the efficacy of indigenous plant extract against H. armigera and M.vitrata in Blackgram. The seasonal incidence of H. armigera and M. vitrata was observed from 38th standard meteorological week (3rd week of September) upto 44th standard meteorological week (last week of October and first week of November). The maximum incidence of H. armigera and M. vitrata was observed during 40th standard meteorological week (2nd week of October) with 17.67 and 12.67 larvae per ten plants, respectively. The correlation of Gram pod borer was found positive with maximum temperature (r=0.074), minimum temperature (r=0.284) and evening relative humidity (r=0.230) and negative correlation with morning relative humidity (r=-0.122) and rainfall (r=-0.017). Spotted pod borer larval population was found as positively correlated with minimum temperature (r = 0.326), evening relative humidity (r = 0.333) and rainfall (r = 0.082) and negatively correlated with maximum temperature (r= -0.022) and with morning relative humidity (r= -0.067) during Kharif, 2022. Among all the indigenous plant extract the best effective treatment Neem oil 20ml/lit of water which reduced the larval population of H. armigera with 4.33, 3.67, 2.33 larvae per ten plant, followed by NSKE 50g/lit of water 5.33, 4.67, 3.67, NSKE+ Cow urine 50gm/lit of water 6.00, 5.00, 4.00, Bacillus thuringiensis 1.5kg/h 6.33, 5.67, 4.33, Agniastra 25ml/lit of water 6.67, 6.00, 5.00 and karanj oil 20ml/lit of water with 7.00, 6.67, 5.67 larvae per ten plants after 3,7 and 10 days of third spray, respectively. Similarly Neem oil 20ml/lit of water was best effective treatment against M. vitrata with 5.67, 4.67, 3.67 larvae per ten plant, after 3,7 and 10 days of third spray followed by NSKE 50g/lit of water 7.00, 6.00, 4.33, NSKE+ Cow urine 50gm/lit of water 7.33, 6.33, 5.67, Bacillus thuringiensis 1.5kg/h 7.67, 7.00, 6.00, Agniastra 25ml/lit of water 8.00, 7.33, 6.67 and karanj oil 20ml/lit of water with 8.67, 8.00, 7.00 larvae per ten plants after 3,7 and 10 days of third spray, respectively. Maximum larval population of H. armigera and M. vitrata was observed in untreated control plot with 11.00, 11.67, 12.67 and 15.33, 16.33, 17.67 larvae per ten plant at 3,7 and 10 days of third spray. Maximum pod infestation was also observed highest in untreated control Neem oil 20ml/lit of water was also found effective in minimizing the pod infestation by H. armigera and M. vitrata with 13.33 and 14.00 per cent, respectively. Maximum pod damage by H. armigera and M. vitrata was also observed from untreated control with 26.67 and 30.33, respectively. The highest grain yield was observed in Neem oil 20ml/lit of water 6.40q/ha followed by NSKE 50g/lit of water 6.0q/ha followed by by NSKE + Cow urine 50gm per lit of water Bacillus thuringiensis 1.5kg/h, Agniastra 25ml/lit of water, and karanj oil 20ml per lit of water with 5.85q/ha, 5.60q/ha, 5.35q/ha and 5.0q/ha, respectively. Lowest grain yield 2.0q/ha was taken from untreated control. The treatment neem oil 20ml/lit of water was found best with maximum returns , Rs 21040/ ha followed by Agniastra 25ml/lit of water, NSKE 50g/lit of water, Bacillus thuringiensis 1.5kg/ha, NSKE+cow urine 50g/lit of water and karanj oil 20ml/lit of water with Rs 20610/ha, Rs 20400/ha, Rs 19385/ha, Rs 18810/ha and Rs 12550/ha, respectively. Among all the treatments, the highest incremental cost benefit ratio was observed in Agniastra 25ml/lit water 1:13.74 followed by, Bacillus thuringiensis 1.5kg/h 1:4.43, NSKE50g/lit of water 1:3.40, NSKE+ cow urine 50g/lit of water 1:2.85 Neem oil 20ml/lit of water, 1:2.63 and karanj oil 20ml/lit of water 1:1.73.
