What characterizes bacterial blight in soybean plants?

• A. Reddish-brown lesions that appear above soil line
• B. Small, angular, translucent lesions
• C. Brown spots on unifoliate leaves
• D. Wet root rot symptoms

Answer: (B)

Bacterial blight in soybean plants is specifically characterized by the presence of small, angular, translucent lesions on the leaves. These lesions are typically water-soaked, which can also give them a shiny appearance. The angular shape occurs because the bacteria affect the leaf tissue in a way that restricts lesion growth along the leaf veins, leading to this distinctive shape. Recognizing these lesions is crucial for early detection and management of the disease, as they can spread quickly, especially under warm, humid conditions that favor bacterial growth. Identifying the symptoms associated with bacterial blight helps farmers and agricultural professionals take timely action to manage the disease and prevent significant crop loss.
