ABSTRACT
In a search for plant extracts with potent antifungal activity against plant pathogenic fungi, the methanol extracts of different medical plants effectively controlled the development of plant diseases caused by Macrophomina phaseolina. The methanolic extracts of forty nine plants hexane, chloroform and methanolic extracts were used for the study, among them methanolic extracts of forty eight medicinal plants exhibited varying degrees of inhibition activity against M. phaseolina, extracts of Tephrosia pumila have no activity. Extracts of Avicenia officinales, Cleome viscose, Grewia arborea, Hyptis sueolences, Ocimum sanctum, Peltophorum pterophorus, Sesbanian grandiflora, Terminalia chebula, Tephrosia pumila, Tephrosia villosa, Withania somnifera showed high activity and Terminalia chebula having strong antifungal activity against M. phaseolina even at low concentrations. Chloroform extracts has very low antimicrobial activity where as hexane has no antimicrobial properties.
