Abstract

Sheath rot disease of rice (Sarocladium oryzae) has become a consequential production constraint in all rice growing countries. The pathogen was isolated from the sheath rot infected rice plants. The antagonistic potential of the bioagents were tested against S. oryzae under laboratory condition. The outcomes of the experiments unveiled that among the bio-agents tested, Pseudomonas fluorescens (BGREB73) was found to be more effective and statistically significant over other bio-control agents in inhibiting mycelial growth (87.20%) followed by T. harzianum (T-13) (84.12%) in dual culture over the control.

Keywords

Rice, sheath rot, Sarocladium oryzae, bioagents

Conclusion

Among all the bio-agents tested Pseudomonas fluorescens (BGREB73) stood out as being more potent and statistically significant in comparison to other bio-control agents with maximum per cent inhibition of 87.20 per cent.
