Bacterial Fruit Blotch
Causal Agent: (bacterium ‑ Acidovorax avenae subsp. citrulli)
Infected seedlings initially develop water‑soaking on the lower surface of cotyledons and leaves (Image 3).
These areas then become necrotic (Image 4).
The pathogen can also cause non-distinctive, necrotic leafspots on transplants (Image 5).
