Utilization of compounds in extracts derived from medicinal plants is vogue now for managing Meloidogyne incognita on crops owing to the unpopular use synthetic nematicides especially Sub-Saharan Africa. In this study, Azadirachta indica A. Juss and Hyptis suaveolens obtained using hexane, chloroform, ethyl acetate methanol were tested their efficacy inhibiting egg hatching inducing larval mortality tomato bioassay maintained Screenhouse. The each solvent reconstituted Tween80+Dimethylsulfoxide (DMSO) evaluated inhibition at concentrations 0.5%, 1.0%, 1.5%. Furadan served as standard checks while distilled water Tween80+(DMSO) controls. Two separate experiments conducted with 39 treatments arranged a Completely Randomized Design (CRD) four repetitions laboratory bench mortality. Ninety (90) µL extract was added 10 suspension containing either 15 eggs or second-stage larvae pipette into cavity glass blocks. Hatching readings recorded 6, 12, 24, 36 hours. Results indicated that Neem mixture all extracted any solvents gave 100% 6th 36th h after treatment application. Only 0.5% chloroform till among lowest concentration mixtures plant extracts. Combined two showed highest activity both but individual only rates used. acute toxicity test most effective Chloroform did not cause sign death animals.
