The Verticillium fungus persists in soil and infects a number of different trees through the roots including catalpa, ash, maple, redbud and sumac. The key soil-borne disease of potato is Verticillium Wilt (early dying), which greatly reduces yields and quality if not carefully controlled, usually by careful soil fumigation after long rotations out of susceptible crops. Verticillium wilt is caused by the soil-borne fungi Verticillium dahliae and V. albo-atrum. Some commonly grown shrubs that are susceptible to verticillium wilt include azalea, daphne, hibiscus, osmanthus, lilac, photinia, rose, spirea, viburnum, and weigela. Other “stone” fruits such as peaches, nectarines, apricots and plums are also damaged or killed by this pathogen.
