Tomato blight is a fungal disease that most often affects tomatoes and potatoes.
It starts by causing distortion of the new growth followed by spots on the leaves. Gradually the whole plant withers, yellows and dies.
How to Protect Your Plant
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.
