Anthracnose

Anthracnose is a fungal disease that attacks trees when the leaves are just emerging. 

Trees commonly infected are ash, white oak, maple, and sycamore.

 

The main symptom of anthracnose is brown, dead areas on the leaves.  These spots tend to start at the leaf veins and expand out toward the leaf margins.

The Anthracnose fungus over-winters in diseased leaf and stem tissue.  In the early spring , spores spread to newly-emerging leaves by wind and rain.  There, new spores are produced, spreading the fungus even further.  There are two factors that determine the severity of infection.  When the temperature in the spring is cool (50-60 degrees) and rainfall is frequent, Anthracnose infection will be high.  Therefore, the severity does vary from year to year.

Even in the most severe years, however, Anthracnose does not typically cause death.  New leaves emerge on infected trees by mid-June.  When defoliation is severe, the tree should have adequate water and should be fertilized to promote new leaf growth.  The trees can be treated with a fungicide, with the first spray being done when the buds first start to open, followed by two more at ten-day intervals.
