When individual branches of a tree suddenly wilt and die while the remainder appears healthy, Verticillium wilt may be the culprit. In addition to maples, this disease affects a wide range of deciduous trees and shrubs, including ash, barberry, catalpa, elm, linden, Russian olive, smoke-tree, and redbud. Vegetable crops such as tomatoes and potatoes are also susceptible. Evergreens are resistant. Verticillium wilt can be found throughout the state, but is more common in southern Wisconsin.
