Leaf blight is identified by irregular brown or black spots on leaves, often surrounded by a yellow halo. These spots may expand, causing the leaves to wilt, curl, and eventually die. Early detection is crucial; look for water-soaked spots that turn necrotic. In humid conditions, you might also see fuzzy mold on the underside of leaves. Vigilant monitoring and removing affected foliage can prevent its spread.
