4.5 O. neolycopersici inoculation and disease evaluation
Plants were grown in the vicinity of O. neolycopersici infested plants in a greenhouse compartment. The naturally infected plants were subjected to 2 RZW cycles followed by three days recovery. The severity of the disease symptoms on leaves was evaluated according to a 0-100% scale where 0=symptomless leaves and 100=fully covered leaves with mycelium and conidia of the fungus (Jacob et al., 2008).
