Shot-hole Disease

Shot-hole Disease Identification

Shot-hole disease (on a laurel in the photos) is a combination bacterial infection (Xanthomonas prunii) and fungal diseases (Blumeriella gaapi and/or Cercospora sp.)

Shot-hole Disease Appearance

Circular holes in the leaves that eventually join and make larger holes. The appearance of shooting a shotgun at the shrub and causing multiple holes.

Shot-hole Disease Hosts

Laurels (bay and Otto Luyken), camellia, ligustrum (privets), hydrangea, ivy.

Shot-hole Disease Season

April through October, peak in May and September.

Shot-hole Disease Damage

Leaves appear to be ‘eaten’ away by the disease, leaving a ragged appearance. As leaves are damaged, they begin to fall away, the plant looses its ability to make food and can become stressed.

Shot-hole Disease Integrated Pest Management

Sanitation is the best way to keep the disease from coming back. Clean up contaminated leaves from under the plant. When diseased leaves build-up under the plant, rain or watering can splash the disease back up on the plant. Spray the leaves with Mancozeb, Kocide, Kop-R-Spray or other recommended products containing copper at the first sign of a problem. Always READ THE LABEL and DIRECTIONS FOR USE section carefully when using pesticides.
