ABSTRACT
Root Knot Nematodes are one of the major economically important pests of tomato (Lycopersicon esculentum L) in many regions of the world including Zimbabwe, with Meloidogyne javanica being considered the most destructive. Recent prohibition of main soil chemical fumigants for the control of Meloidogyne javanica has prompted for the search of other alternatives to manage root knot nematodes. A greenhouse experiment was carried out to evaluate the effects of aqueous plant extracts on (Lantana camara, Tagetes minuta and Amaranthus hybridus) with a negative and positive control where negative control had only water and positive control had a chemical nematicide (Nemacur®400 Ec (fenamophos as the active ingredient) on Root Knot Nematode (Meloidogyne Javanica) suppression in tomato seedlings. The experiment was arranged in a Completely Randomised Design (CRD) with five treatments and three replications. A Meloidogyne Javanica inoculum was obtained from Tobacco Research Board (TRB) and botanical plant leaves were obtained locally and aqueous plant extracts were prepared. Data collected were days to 50% emergence, seedling height, final nematode population density, gall density and index and root: shoot ratio. There was a significant difference (P
