Leaf spot is a common plant disease characterized by the appearance of dark, round, or irregular spots on leaves. These spots can vary in color, including brown, black, or yellow, and may lead to leaf yellowing and premature drop. Leaf spot is often caused by fungi, bacteria, or environmental factors, and it can affect a wide range of plants, including vegetables, flowers, and ornamental plants. To manage leaf spot, it is essential to maintain proper plant care, including adequate spacing for air circulation and avoiding overhead watering. Infected leaves should be removed and disposed of to prevent the spread of the disease. Fungicides or bactericides may also be used as a treatment option, depending on the specific cause of the leaf spot.
