Damping-off primarily affects which stage of plant development?

• A. Mature plants
• B. Seedlings after emergence
• C. Seedlings at or before emergence
• D. Harvest time

Answer: (C)

Damping-off is a disease of the very young plant that targets seeds and seedlings as they are germinating or just emerging. The pathogens—often soilborne ones like Pythium, Rhizoctonia, or Fusarium—thrive in wet, crowded conditions and attack the delicate stem tissue at the soil line. Because the trouble happens during germination or right as the seedling is coming up, the stage affected is at or before emergence. Once plants are established as mature seedlings or larger, damping-off is much less of a threat, and it isn’t linked to harvest time. To reduce it, manage moisture, improve drainage and airflow, and use clean growing media.
