Abstract

Present study focuses on the use of bacterial isolate Pseudomonas OG101 against the Fusarium sp. and its growth promoting ability for chickpea (Cicer arietinum) and cowpea (Vigna unguiculata) plants. Pseudomonas strain OG101 controls mycelial growth of Fusarium oxysporum f.sp. ciceris and F. oxysporum f.sp. pallidoroseum up to 24.4% and 20.5%, respectively. In addition, OG101 showed a significant improvement in the germination index of 93.3% and 98.3% with disease index of 1.6% and 3.3% in chickpea plant and cowpea plant, respectively. Pot experiments of chickpea and cowpea plants refer to use it as a seed bacterization for the best effect for growth promotion and its biocontrol activity against F. oxysporum f.sp. ciceris and F. oxysporum f.sp. pallidoroseum respectively.
