Black Spot is a disease that primarily affects which plant group?

Explanation:
Black Spot is a classic fungal disease that primarily targets roses. The pathogen that causes it specializes in infecting rose leaves, producing round black spots and causing yellowing and leaf drop in humid conditions. Because this disease is most commonly associated with roses, other plant groups like conifers, grasses, or citrus aren’t the typical hosts for Black Spot, making roses the best answer. In practice, management centers on removing infected leaves, improving air circulation, and applying appropriate fungicides when necessary.
