These isolates were identified as V. dahliae, V. albo-atrum and V. tricorpus on the basis of their morphological and cultural characteristics. Four isolates of V. dahliae, two isolates of V. albo-atrum and two isolates of V. tricorpus were examined for their mycelial growth at different incubation temperatures and their virulence against tomato and eggplant cultivars. Seedlings at the three leaf stage were root-dipped in a conidial suspension (107 conidia mL-1) and maintained in the glasshouse at 21-25°C. Disease severity was assessed through the index of leaf damage and plant height, recorded eight weeks after inoculation. Growth test showed that the majority of Verticillium isolates were able to grow from 10 to 30°C. All tomato and eggplant seedlings exhibited typical Verticillium symptoms compared to the non-inoculated control. The index of leaf damage, as well as plant height, differs significantly depending on cultivars and isolates. V. albo-atrum and V. tricorpus were moderately to highly pathogenic against eggplant and tomato plants. V. dahliae was the most aggressive against these hosts, showing a high level of pathogenicity to both eggplant and tomato plants.]]>Barbara, D.J. and E.
