Screening of bioagents against root rot of mung bean caused by Rhizoctonia solani.
A laboratory and green house experiment was carried out on the comparative antagonistic performance of four different bioagents (Aspergillus sp. Gliocladium virens, Trichoderma harzianum and T. viride) isolated from soil against Rhizoctonia solani. Under laboratory conditions, T. harzianum exhibited maximum (75.55%) mycelial growth inhibition of R. solani. This was followed by T. viride, which showed 65.93% mycelial growth inhibition of the pathogen. Gliocladium virens was also found to be effective antagonists, which exhibited 57.77% mycelial growth inhibition. While Aspergillus sp exhibited minimum growth inhibition (45.74%) in comparison to other bioagents. Under green house conditions, T. harzianum gave maximum protection of the disease (72.72%) followed by T. viride, which exhibited 54.54% disease control. However, G. virens and Aspergillus sp were found least effective in controlling root rot of mungbean.
