The Iowa State University Plant & Insect Diagnostic Clinic frequently receives inquiries regarding trees with foliar chlorosis (yellow leaves), browning from the edge of the leaf in, and wilting appearance of limbs or whole sides of a tree. Trees and ornamental shrubs can suffer from vascular wilt pathogens. These pathogens enter the vascular system that move water from the roots upwards. The pathogens then colonize the vascular system, and impeded water movement to the branches, resulting in yellowing and browning of the leaves, and the wilted look of twigs and limbs.
