The influence of some bio-agents viz., Nemaless, Bacillus thuringiensis B.t.NRC60 and Promot in controlling Meloidogyne incognita on banana cv. Williams after 15 and 45 days of inoculation were studied under greenhouse conditions. Data indicated that the second stage juveniles (J2) significantly decreased (P ≤ 0.05 and / or 0.01 levels) by all the bio-agents. Other development stages within roots, galls, egg-masses and the rate of nematode build-up also decreased as compared to the untreated control. Also, all treatments, each with three levels, significantly increased plant growth parameters as compared to untreated control. The application of Abamectin (bio-agent) and Oxamyl (Nematicide) injected in plant pseudostem or poured on plant top on banana cv. Williams at three doses, significantly decreased (P ≤ 0.05 and / or 0.01 levels) population densities of M. incognita under greenhouse conditions. The application methods of injection or pour onto plant did not have any significant difference in terms of nematode population and their rate of build-up. However, all treatments, significantly increased plant growth parameters (P ≤ 0.05 and / or 0.01 levels) as compared to untreated plants.
