Abstract

Fusarium wilt is one of the distructive disease of tomato caused by Fusarium oxysporum f.sp. lycopersici is one of the most widespread disease of the tomato. The fungus Fusarium causes the vascular wilt disease in tomato known as fusariosis and in case of severe disease incidence its resulting in total and complete loss of yield under field and greenhouse condition. Therefore, present study was undertaken during, kharif, 2021-22 in the Department of Plant Pathology, VNMKV, Parbhani to assess the bioefficacy of seven phytoextracts against F.oxysporum f.sp. lycopersici. Results revealed all seven test plant extracts (each @10 and 20 %) were found fungistatic to F. oxysporum f.sp. lycopersici and significantly inhibited mycelia growth of the test pathogen, over untreated control. Among plant extracts Allium sativum was recorded complete mycelial growth inhibition of F. oxysporum f.sp. lycopersici with cent percent inhibition over control and significantly superior over all the treatments followed by Zingeber officinale (86.78% and 87.66% at respective concentration) with mycelial growth of 13.23 mm and 11.89 mm respectively. whereas, the least effective phytoextract was found Mentha piperita (54.26% and 55.37%) with maximum mycelial growth of 45.17 mm and 41.16 mm at respective concentration

Keywords

F. oxysporum f.sp. lycopersici, Lycopersicion esculentum, Phytoextracts, Allium sativum, Zingeber officinale, Oscimum sanctum, Mentha piperita, Azardirachta indica

Conclusion

It is concluded from above result that, the plant extracts evaluated in vitro, Allium sativum, C. longa, Z. officinale and A. cepa were proved to be most efficient in inhibiting significant mycelial growth of F. oxysporum f.sp. lycopersici. Thus, locally available plant species with antimicrobial properties and antagonistic microorganisms can be used as an alternative to the chemicals, to manage wilt of tomato
