Septoria Leaf Spot

Septoria lycopersici

Note: Click on the image(s) above to see larger version.

Symptoms:
Circular water-soaked lesions occur first on older leaves. These spots eventually turn brown with gray centers and die, and if infection is severe enough, the entire leaf will die.

Control:
The fungus can survive in the debris from previous crops and/or weeds. Clean cultivation is important. The disease can be controlled by labelled fungicides.
