Target Spot

Corynespora cassiicola

All above ground parts of the plant can be affected. Target spot begins on leaves as yellow leaf flecks, which later become angular with a definite outline. The spots become circular with light brown centers surrounded by dark brown margins. Lesions coalesce to produce large dead areas with dead and shedding leaves. The most damaging aspect of scab is on the fruit. Small, sunken spots (3-4 mm) are the initial fruit symptoms. The spots can be mistaken for insect damage or anthracnose. An additional problem secondary bacteria that come in after scab has started, causing a soft-rot.
