Abstract:
In the present investigation, efforts were made to test the bio-efficacy of different plant extracts viz; Garlic, Neem, Datura, Calotropis, Turmeric and Asafoetida on the mycelial growth of predominantly occurred pathogen on grain discoloration, Curvularia lunata using poisoned food technique. Observations on radial growth were recorded after control plate fully occupied by the pathogen. Percent inhibition over control was calculated. Among all the plant extracts Garlic extract was highly effective resulted complete inhibition (100%) at all the concentrations (2%, 3%, 4%, 5%) followed by Neem extract resulted complete (100%) inhibition at 15 per cent and 20 per cent concentrations over the mycelial growth of the pathogen compared with other plant extracts and control.
