What type of pathogen often results in diseases affecting plant health?

• A. Viruses
• B. Fungi
• C. Bacteria
• D. All of the above

Answer: (D)

The correct answer encompasses all types of pathogens, as each type—viruses, fungi, and bacteria—can independently result in diseases that significantly affect plant health. Viruses can infect plants, leading to symptoms such as mottling, stunting, and leaf curl, often debilitating the plant’s growth and productivity. Fungi are responsible for a wide range of plant diseases, including root rot, wilt, and leaf spots, which can destroy crops and ornamental plants alike. Bacteria can also be detrimental, causing diseases characterized by soft rot, blights, and galls, ultimately impacting plant vitality and yield. By recognizing that all these pathogens can lead to plant diseases, one understands the broad spectrum of threats to plant health. This awareness is crucial for effective disease management and sustainable agricultural practices.
