A blight spot is a plant disease symptom characterized by brown-black leaf spots that often grow in target-like, concentric rings. These spots appear dry, unlike the water-soaked spots associated with gummy stem blight. As the disease progresses, the affected leaves turn brown, curl up, and eventually die.
Here's a breakdown of the characteristics:
- Appearance: Brown-black spots on leaves.
- Pattern: Often arranged in concentric rings, resembling a target.
- Texture: The spots appear dry, not water-soaked.
- Progression: Leads to browning, curling, and death of the affected leaves.
It is important to distinguish leaf blight spots from other similar diseases. The presence of dry, target-like spots is a key identifier.
