Pathogenicity of Root-knot Nematode, Meloidogyne incognita on Cluster Bean (Cyamopsis tetragonoloba)

摘要

The production of vegetables is very low due to many biotic and abiotic factors including losses caused by plant parasitic nematodes. The root-knot nematode, Meloidogyne incognita is one of the most prevalent species found associated with cluster beanin India. Farmers experience chronic losses because of the high frequency of this nematode (Parvathareddy 1986; Jain et al 2007). We attempt to estimate the level of root-knot nematode, Meloidogyne incognita at which it may be considered as pathogenic to cause economic damage to cluster bean.
