Abstract:
Root-knot nematodes (Meloidogyne spp.) are among the most destructive plantparasiticnematodes, causing significant yield losses in tomato and other cropsworldwide. Meloidogyne enterolobii is of particular concern due to itsaggressive nature, wide host range, and resistance-breaking ability. This studyevaluated the efficacy of selected non-fumigant chemical nematicides(Fluensulfone, Fluazaindolizine, Fluopyram, and Oxamyl) and bionematicides(lignin- alkali at two concentrations and Majestene) for the management of M.enterolobii in greenhouse-grown tomato. Tomato plants were inoculated with29,400 eggs per pot, followed by nematicide drench applications. Parametersmeasured included root galling index, nematode reproduction factor, eggdensity, and plant growth traits. Results indicated that Fluensulfone significantlyreduced galling, egg density, and reproduction factor, while Fluopyramimproved shoot growth and Oxamyl enhanced root growth. Amongbionematicides, the high-concentration lignin-alkali treatment effectivelysuppressed nematode infestation and promoted plant growth. These findingshighlight the potential of integrating chemical and biological nematicides into anintegrated nematode management (INM) framework, offering sustainablealternatives for tomato production in the absence of fumigants.
