Abstract:

Two separate greenhouse pot experiments were conducted and the effect of the seedling age at inoculation and the mechanical wounding of roots on the development and severity of charcoal root rot/root-knot disease complex caused by the interaction between Macrophomina phaseolina and Meloidogyne javanica on green beans cv. �??Contender�?� were examined. Results showed that as the age of seedlings at inoculation increased from 4 to 6 weeks, the severity of the disease complex decreased and the nematode reproduction was suppressed. However, the mechanical wounding of roots at inoculation with both pathogens increased the root-rot index, root galls, fungal re-isolation (%) and number of eggs/roots, while decreasing the plant growth.
