However, resistant eggplant com- mercial cultivars are not available against Verticillium- induced wilt, and methods used to control vascular wilt pathogens by agronomic techniques (i.e., crop rotation) have been only partially effective due to the huge host range of the pathogen and to the long span of microsclerotia, its resting structures in soil. The disease will progress to other leaves and stems, and finally the root system.
