Late Blight

Late Blight
Phytophthora infestans

Symptoms:
Lesions on leaves appear as large watersoaked areas, that eventually turn brown and papery. Lesions may be surrounded by a white ring of mold if leaf wetness is high. Green to black irregular lesions are also present on the stems.

Control:
The fungus develops during periods of cool wet weather. Fungicide sprays as a preventative measure during these periods may be needed if the crop is being grown near large areas of tomato relatives (Solanaceous weeds, potatoes).
