Online published on 21 January, 2023. Abstract Fennel (Foeniculum vulgare Mill.) popularly known as “Saunf” is one of the important and highly valued spice crops grown in India. Fusarium solani is the most common pathogen in causing root rot of fennel with qualitatively and quantitatively losses. Development of disease in cultivated crops depends on the complex interaction between host, pathogen and prevailing environmental conditions. The significant role of nematodes in aggravating fungal diseases is well known in many crops throughout the world. In lieu of this, present study was planned to know the interactive effect of Meloidogyne javanica in enhancing the incidence of root rot by Fusarium solani. The experiment was laid out in a completely randomized design with four replications in pot conditions. The results of the experiments showed that inoculation of nematode at the time of sowing and fungus one week after caused maximum reduction in plant growth parameters and increased disease incidence followed by simultaneous inoculation of nematode and fungus in comparison to check. Whereas, maximum nematode reproduction was recorded in nematode alone followed by N+F. Conclusively, presence of root damaging nematodes in rhizosphere zone of plants plays an important role in enhancing incidence of root rot diseases.
