| Abstract/Description: | Effect of bio-control agent (Paecilomyces lilacinus), neem cake and botanicals (Tagetes erecta and Solanum torvum) against root-knot nematode, Meloidogyne incognita in cv. Robusta was tested by applying individually and in combinations under pot condition. Results revealed that all the treatments were effective in increasing the plant growth with significant reduction in nematode populations. Among the treatments, the combined application of P. lilacinus + neem cake and P. lilacinus +T. erecta (flower extracts) resulted in maximum increase of plant height (5.3 cm each), number of leaves (26.6 & 25.0), pseudostem girth (11.7cm &11.0 cm), root length (36 & 26), number of healthy roots (42 & 43), root weight (45 each), root gall index (1) and nematode population from soils (30 & 50/250cc) and roots (110 & 115/5g) compared to the maximum root gall index (5) with the nematode population from soil (1020/250 cc) and roots (1760/5g) in nematode alone- inoculated control plants. The estimation of proteins, phenol, peroxidase and polyphenol oxidase detected from roots and leaves showed an increase in total orth-dihydroxy phenols and enhanced activities of polyphenol oxidase and peroxidase on inoculation of M. incognita. |
| Description: | Banana (Musa spp.) is one of the important commercial fruit crops grown widely in both tropical and sub-tropical conditions under different production systems. The root-knot nematode, Meloidogyne incognita considered to be the most economically important nematode pests of banana is widely distributed in South India (Sundararaju, 1996). Crop losses caused due to M. incognita in ‘Poovan’ was reported to be 30.9% (Jonathan & Rajendran, 2000). Management of nematode problems by indiscriminate use of nematicides has proved disastrous to the environment and human. Incorporation of organic amendment like neem cake, botanicals and bio-control agents have shown to be most effective ways to manage nematodes without affecting the produce (Jonathan et al. 1995; Sundararaju & Cannayane, 2003; Sundararaju & Kumar, 2003). Since, the nematodes are very well managed by using organic amendments/bio-control agents in different horticultural and plantation crops, an attempt was, therefore, made to evaluate the efficacy of bio-control agent (Paecilomyces lilacinus), organic amendment (Neem cake) and botanicals (Tagetes erecta and Solanum torvum) individually and in combination for the management of root-knot nematode problem on banana cv. Robusta. |
