ABSTRACT

A field experiment was conducted to determine the efficacy of different insecticides against Helicoverpa armigera (Hubner) infesting chickpea at Junagadh Agricultural University campus, Junagadh during rabi season of 2008-09. The results revealed that flubendiamide 0.007 per cent, indoxacarb 0.0075 per cent, spinosad 0.009 per cent and emamectin benzoate 0.0015 per cent were found the most effective in reducing the H. armigera population and pod damage of chickpea. The highest yield was also recorded in the treatment of flubendiamide 0.007 per cent (1850 kg/ha) followed by indoxacarb 0.0075 per cent (1805 kg/ha), spinosad 0.009 per cent (1760 kg/ha) and emamectin benzoate 0.0015 per cent (1665 kg/ha). The highest cost benefit ratio was obtained in the treatment of indoxacarb 0.0075 per cent (1: 7.08), followed by flubendiamide 0.007 per cent (1:6.10) and spinosad 0.009 per cent (1:5.24). Thus, considering the cost benefit ratio, any one of these insecticides spray at 50 per cent flowering and second at 15 days after first spray can be suggested for the effective control of gram pod borer on chickpea.
