Antifungal activity of some medicinal plant extracts against soil-borne phytopathogens

In the present study, the extracts of different plant parts were used to control the growth of soil-borne fungi viz., Fusarium oxysporum, Macrophomina phaseolina and Rhizoctonia solani. Five plants including Amaranthus viridis, Euphorbia hirta, Chenopodium album, Solanum nigrum and Carica papaya were selected to check their antifungal and inhibition activity against soil-borne phytopathogens. The different parts of plants such as leaves, stems and fruits were dried and grounded for powder extract. The powder extract of three different concentrations 1, 3 and 5% were prepared and used against the soil-borne fungi by disc diffusion and food poison methods. Almost all plants showed antifungal activity against the F. oxysporum, M. phaseolina and R. solani. A. viridis and E. hirta showed maximum inhibition potential activity in disc diffusion method against above mentioned soil-borne pathogens as compared to other three plants, therefore A. viridis and E. hirta can be utilized for antifungal management of fungal diseases, particularly F. oxysporum, M. phaseolina and R. solani.
