Pathogenicity Study and Nematoxic Properties of Some Plant Extracts on the Root-Knot Nematode Pest of Tomato, Lycopersicon esculentum (L.) Mill
T.I. Olabiyi

Abstract:
In the screen house, tomato seedlings, cv. DT 69/257, grown in steam-sterilized soil were inoculated with graded inocula of 5,000; 10,000; 15,000; 20,000 and 25,000 eggs of root-knot nematode, Meloidogyne incognita. At inocula levels of 15,000; 20,000 and 25,000 eggs of M. incognita, number of leaf per plant, plant height, fruit yield and root galls were significantly reduced. In the field planted with tomato seedlings, aqueous extracts from the roots of marigold, nitta and basil plant were applied to root-knot nematode inoculated soil at four levels of 25,000; 500,000; 750,000 and 1,000,000 ppm concentrations, 10 mL per tomato stand. All the aqueous plant root extracts applied in the trials reduced root-knot nematode populations in the soil with corresponding increases in plant height, plant leaf and fruit yield over the control treatment. Significant reduction of root galls from the treated plots indicated effective root-knot nematode control by the aqueous root extracts.

Hadi Bawa:
This paper is interesting as it gives me more hints on how to carry ou research on Root knot and other plant parasitic Nematodes. Hence forth, you may provide me with more papers when the need the need arise.
Thanks and God bless you abundantly.

Sir,
Your research paper is very interesting and found very much semilar to my research work mainly on nematode control using botanicals. You may please quot semilar journal articles to me. God bless you.
Thanks
