Abstract:
It was observed that M. obtusa preferred 2ndlocule most, followed by 3rd, 1st, 4th, and 5thlocules in both cultivars during 2012-13 but present sequence were slightly changed and 5thlocule was not preferred in Narendra Arhar 1 during 2013-14. The maximum level of parasitization 25.00 & 22.22 per cent during 2012-13 and 12.50 & 4.87 per cent during 2013-14 was observed by Ormyrusorientalisin Narendra Arhar 1 and Bahar. Emamectin benzoate 5 SG @ 11g a.i. showed minimum infestation 2.60% and 2.40% respectively, on Narendra Arhar 1 during 2012-13 & 2013-14 and gave maximum and significantly more protection to pods. It was followed by spinosad 45 SC, novaluron 10EC, indoxacarb 14.5 EC, imidacloprid 17.8 SL, and acephate 75 SP. Emamectin benzoate 5 SG 11g a.i. registered 10.30 and 8.20 per cent pod damage, 6.00 and 5.20 per cent grain damage and 22.20 and 20.00 per cent weight loss respectively, on Narendra Arhar 1 during 2012-13 and 2013-14. Emamectin benzoate 5 SG @ 11g a.i./ ha was found most effective and produce higher grain yield 16.50 and 18.00 q/ha on Narendra Arhar 1 during 2012-13 and 2013-14 followed by Spinosad 45 SC 60g a.i., novaluron 10EC 100g a.i., indoxacarb 14.5 EC 60g a.i, Imidacloprid 17.8 SL60g a.i. and Acephate 75 SP 600g a.i. The least effective treatment was acephate 75 SP 600g a.i. /ha which produced grain yield of 11.20 and 13.00q/ha, respectively during 2012-13 and 2013-14. Highest cost benefit ratio 1:7.2 and 1: 8.5 respectively, during 2012-13 and 2013-14 were obtained from the plots treated with emamectin benzoate 5 SG 11g a.i. /ha followed by spinosad 45 SC 60g a.i.
