The fungus that causes this disease is soil-borne. It invades the water-conducting vessels of the tree and inhibits water flow, leading to wilt, yellowing, leaf drop, and/or gradual dieback. There are no controls for the disease. The fungus produces spores on the dead tree. These spores can be washed into the soil and cause infections of other mimosa trees. Infected trees, including the stumps, should be removed to prevent spread.
