Leaves may drop, leaving fruit open to sunscald.

Similarly, does tomato blight stay in the soil? Blight spores can survive in the soil for three or four years. Throw out and replace young transplants that appear to be in the early stages of fungal infection, and, if blight appears in young plants after transplanting, remove the infected leaves so that the spores do not make their way into the soil.

In respect to this, can you eat tomatoes with blight?

Does baking soda kill tomato blight?

Baking soda has fungicidal properties that can stop or reduce the spread of early and late tomato blight.

Early blight is caused by the fungus Alternaria solani, which survives in plant debris or on infected plants. Early blight symptoms typically begin as plant canopies start to close. Denser foliage leads to high humidity and longer periods of leaf wetness that favor the disease.

Does blight live in the soil?
