Alternaria solani
Early Blight of tomatoes is a fungal disease that most often affects tomatoes, potatoes, capsicums and eggplants.
Black to brown circular lesions on leaves, stems and fruit. Leaves often turn yellow, wither, then die. Reduced plant health and vigour, possibly leading to plant death.
The disease is difficult to treat once established but its entry into the plant can be prevented by spraying with a protective fungicide. Early blight often occurs during humid weather and is most likely to attack plants under stress. Remove dead or damaged leaves and make sure there’s good air movement around the plant.
