Anil Kumar, MK Tripathi, Umesh Chandra and Ram veer

The experiment was conducted at Agriculture farm, Department of Entomology, Tilak Dhari post Graduate College, Jaunpur during Rabi season 2010-11 and 2011-12. Studies on Neem Seed Kernel extracts @ 5% performed best among the treatments followed by, Bt. 1 kg/ha, Neem oil @ 2 %, Nimbecidine @ 2 %, HaNPV @450LE/ha and Neem leaf Extract @ 5 % with 1.90, 4.70, 4.80, 4.90, 5.20, 5.30, and 5.4 mean larval population of Helicoverpa armigera larvae per meter length, respectively in that order NSKE @5% were significantly superior over other treatments. The efficacy of various treatments at this stage was in order of Neem Seed Kernel Extract @5% > Bt. 01 Kg/ha > Neem oil @ 2 %> Nimbecidine @ 2% > Neem leaf extracts @5% > NPV@450LE/ha. Spray of NSKE @ 5% proved significantly lower pod damage of 13.45 % and 12.76% in 2010-11and 2011-12 followed by and Bt. 1 kg /ha 14.10 in the first year and 13.38% in the second year.
