INVITRO ANTIFUNGAL POTENTIAL OF DIFFERENT PLANT SOLVENT EXTRACTS AGAINST COMMON ROOT-ROT FUNGI
Tuba
Abstract
ABSTRACT A study was conducted to examine antifungal property of water, n-hexane, chloroform and ethylacetate extracts of some wild plants of Karachi such as Cyamopsis tetragonoloba (L.) Taub, Fagonia indica Burm f., Hibiscus rosa-sinensis L., Melia azedarach L., Prosopis juliflora (Sw.) DC., Rhynchosia minima (L.) DC., Solanum surattense Burm f., Terminalia catappa L., Thespesia populnea (L.) Sol. ex Corrêa, Withania somnifera (L.) Dunal against common root-rot fungi viz., Fusarium oxysporum Schltdl., Macrophomina phaseolina (Tassi) Goid and Rhizoctonia solani (Kühn) by food-poisoned method. Plants water extract showed varied inhibitory percentage. 100% inhibition of R. solani was seen in T. populnea (leaves & fruit), M. azedarach (stem and fruit) and P. juliflora (leaves) extracts, while F. oxysporum inhibited 95.93% by W. somnifera (stem) extract, however S. surattense inhibit 85% growth of M. phaseolina. Among all n-hexane extract of plants 100% inhibition of R. solani was done by M. azedarach (leaves and fruit) and P. juliflora (leaves). Maximum 84.44% inhibitory effect of F. oxysporum was seen by T. populnea (fruit), while maximum 74.82% suppression of M. phaseolina has been done by T. catappa extract. Chloroform extract of all plants proved good inhibition of tested fungi. 100% control of R. solani observed in T. populnea (fruit). Maximum 85.55% inhibition of F. oxysporum exhibited by P. juliflora (leaves), whereas inhibitory effect of M. phaseolina was 93.71% by M. azedarach (leaves). Among all ethylacetate extracts, T. populnea (fruit) and P. juliflora (leaves) suppressed 100% growth of tested fungi. On the basis of results it was concluded that almost all plant solvent extracts controlled the growth of fungi. It can be said that these wild plants possess natural antifungal compounds that can be used to control these root-rot fungi. KEY WORDS: Antifungal, root-rot, solvent extracts, food-poisoned, wild plants.
