Do ginkgo trees have phytophthora?
Ginkgos typically have good disease resistance, but Phytophthora root rot occasionally occurs. The soil-borne pathogens thrive in overly wet soils, entering the tree through its roots and working their way up into the lower trunk. The leaves on infected trees often look discolored and dry, while the affected trunk tissue darkens, dies and sometimes oozes a dark sap. Infected trees often wilt and die within a few years, if left untreated. The pathogens can live in warm, moist soils up to several years without a host and spread quite easily through splashing water.

In addition, twigs and branches die. Leaf scorch symptoms resemble other stress-related problems and the only way to know if your gingko tree has been infected is through a lab test. The leaf scorch bacteria is spread by leafhopper insects although, according to the University of Kentucky Extension website, the exact method by which it spreads isn't known. The bacteria damages trees by infecting the vascular tissue and blocking the ability of the tree to transport water and other nutrients to the leaves.
