Abstract:
A pot and lab experiment was conducted to evaluate the efficacy of selected compatible bio-control agents viz. Verticillium lecanii (T1), Beauveria bassiana (T2), Metarhizium anisopliae (T3), Trichoderma viride (T4) and botanicals viz. Tea wastage (T5), Neem leaf extract (T6), Allamanda leaf extract (T7) against the pathogen of rhizome rot disease responsible for ginger decline. The selected bio-agents were applied as a bio-fortified material. The bio-control agents were bio-fortified with the selected substrates; cow dung, mustard oil cake, poultry manure, dust and wheat grain. Data on disease incidence and disease severity was recorded at 50, 70 and 90 Days After Planting (DAP). Among the selected compatible bio-control agents, the lowest disease incidence and severity was found in T3 (Metarhizium anisopliae) and the highest in T1 (Verticillium lecanii). Among the selected botanicals, the lowest disease incidence and severity was found in T5 (Tea wastage) and the highest in T7 (Allamanda leaf extract). No disease symptoms were appear in T6 (Neem leaf extract) treatment up to 90 DAP or up to harvesting. From the in-vitro management study it was found that Trichoderma viride (T4) and Metarhizium anisopliae (T3) gave better performance in inhibiting radial mycelial growth of the pathogen of rhizome rot disease, Fusarium oxysporum. Among the botanicals, neem leaf extract gave promising performance in inhibiting radial mycelial growth. However, from the present study it may be concluded that Metarhizium anisopliae, Trichoderma viride and neem leaf extract can be used for effective management of rhizome rot disease of ginger.
