sweet orange scab

The disease has been reported by a number of countries in South America and Oceania. In June 2010, it was first confirmed in the United States in Texas.

Sweet orange scab is a fungal disease that results in unsightly, scab-like lesions developing on fruit rinds and, less often, on leaves and twigs. The damage produced is superficial and does not affect internal fruit quality or taste.

The fungus is easily dispersed by rain or irrigation and can be carried on infected nursery stock such as ornamental citrus plants and fruits. Insects also can spread the fungus when carrying fungal spores on their bodies.

Infected fruit is more likely to drop prematurely, and the scabby lesions reduce the fruit’s fresh market value. In addition, the disease may stunt young citrus seedlings.
