Symptoms of early blight usually begin after the first fruit set on tomato plants, starting with a few small, brown lesions on the lower leaves.
-
As the lesions progress, they take on the shape of target-like rings with dry, dead plant tissue in between.
-
The surrounding plant tissue turns yellow, then brown before the leaves die and drop from the plant.
-
While early blight does not directly affect the fruit, loss of protective foliage from exposure to direct sun can damage the fruit. That condition is called sun-scald.
