Effect of soil amendments on pathogenicity of Meloidogyne incognita on okra



Effect of soil amendments on pathogenicity of Meloidogyne incognita on okra



International Journal of Pest Management 39(4): 385-389



Effects of chicken manure, goat manure, kale leaves, nitrogen-potassium-phosphorus (N-P-K) (20:10:10) fertilizer, maize stalks, sawdust and bean stems on pathogenicity of Meloidogyne incognita (Kofoid and White) Chitwood on okra (Hibiscus esculentus L. c.v. Pusa Sawani) were evaluated under glasshouse and field conditions. Results revealed that chicken manure, goat manure, kale leaves, N-P-K (20:10:10), maize stalks and sawdust suppressed pathogenic effects of M. incognita by up to 75.69%, 68.89%, 67.24%, 90.25%, 67.24% and 22.09%, respectively. Bean stems did not suppress pathogenic effects of M. incognita, as was revealed by poor plant performance and high disease severity. Gall indices of up to 3.40 on a 0-4 rating scale were obtained from plants grown in soils amended with bean stems.
