Evaluation of Bacillus subtilis for the management of dry root rot and vascular wilt of chickpea

Author(s): KP Smitha, E Rajeswari, CD Alice and T Raguchander
Abstract: The present study was conducted to evaluate the efficacy of a novel rhizospheric Bacillus strain with multifaceted biocontrol efficacy for the effective management of wilt and root rot of chickpea. Among the 30 Bacillus isolates screened, the strain CaB5 was selected based on in vitro inhibition, growth promotion and presence of antibiotic biosynthetic genes. Bacillus subtilis CaB5 was formulated in talc in which the population of Bacillus was found to be stable at 108 till 105 days. Glass house studies revealed that CaB5 (seed treatment @ 10 g/kg seed + basal application @ 2.5 kg/ha followed by soil application of CaB5 at 45 days after sowing) reduced wilt and root rot in chickpea by 72.0 and 61.1 per cent respectively. The pooled analysis of two field experiments revealed that the same treatment reduced the wilt and root rot in field by 60.5 and 62. 8 per cent respectively.
