Antifungal potential of Parthenium hysterophorus L. plant extracts against Fusarium solani

摘要

Fusarium wilt, caused byFusarium solani(Mart.) Sacc,is an economically important disease of potato in Pakistan. Recent studies have shown that plant pathogens can be controlled by plant products as these are biodegradable, exhibit structural diversity and complexity. Presently, antifungal bioassays were conducted to confirm mycotoxic potential of root, shoot and leaf ofParthenium hysterophorusL. againstF. solaniFCBP-434 using 1 to 4% concentrations of aqueous, methanol and n-hexane extracts.Bioassays revealed thatgrowth ofF.solaniwas greatly inhibited at 1 and 2% concentrations of aqueous and methanol leaf and stem extracts while 3 and 4% concentrations of n-hexane extract proved to be more effective in suppressing growth. Among root extracts, higher concentrations of aqueous and n-hexane exhibited more promising results by causing reduction of 85 and 74%, respectively; whereas, in methanol extract again, lower concentrations were more inhibitory. The study concludes that aqueous and organic extracts ofP. hysterophorushave potential to obstruct dreadful effect of pathogenic fungi by suppressing their growth.P. hysterophorusconferred vital and surprisingly stable compounds having inhibitory potential againstF. solaniFCBP-434.
