Antifungal volatiles from medicinal herbs suppress Fusarium oxysporum f. sp. lycopersici

Medicinal herbs are the potential sources for antimicrobial compounds against soil-borne pathogens. The present investigation focuses on assessing efficacy of antifungal activity volatile organic (VOCs) produced by seven different medicinal in suppression F. oxysporum f.sp. lycopercisi, causal agent wilt disease tomato plants. Among samples tested in-vitro, blend VOCs emitted from mint (Mentha spicata) leaves inhibited mycelial growth o. lycopercisi up to 41.88% followed lemongrass (39.44%) and nochi (34.66%). important were identified through Headspace – Gas chromatography coupled with Mass Spectrophotometry (HS-GCMS) which revealed presence around 25 varied functional groups. them -(-) carvone obtained had highest relative abundance (2.08% peak area at 10.25 RT). In addition, geraniol citronellol also a percentage 15.85 10.37 RT 5.27 9.97 RT, respectively. Pure carvone, (Sigma Aldrich) along plant vitro comparison inhibition f. sp. lycopercisi. samples, was found be most effective suppressed pathogen 100% 500 ppm, (up 90% inhibition) partition plate method. results indicated that could explored an additive effect management other Integrated Disease Management (IDM) practices.
