What are the three categories of diseases that can affect seeds and seedlings?

• A. Fungal, Bacterial, Viral
• B. Bacterial, Chemical, Mechanical
• C. Fungal, Mechanical, Viral
• D. Cultural, Bacterial, Soil

Answer: (A)

The identified categories of diseases that can impact seeds and seedlings are fungal, bacterial, and viral. This classification is essential for understanding how various pathogens can affect plant health right from the seed stage. Fungal diseases are prevalent and can lead to issues such as seed rot or damping-off in seedlings. Bacterial diseases can also significantly harm seedlings, often causing wilting, decay, or stunted growth. Viral diseases may lead to symptoms like mottling or distortion in leaves, which can severely affect overall plant vigor and yield. Recognizing these three categories helps in developing appropriate treatment and management strategies to protect seeds and seedlings from potential diseases, ensuring healthy plant development. The other options mention categories that either do not align with recognized disease classifications or include factors that don't pertain to diseases, such as cultural practices or mechanical injuries.
