“Damping-Off” occurs at various stages during seed germination and subsequent seedling growth. It is caused by soil fungi like Pythium, Fusarium, Rhizoctonia, Sclerotinia and Sclerotium.

Control requires the elimination of the organisms completely during propagation. Also the control of plant growth and environmental conditions will minimize the effects of “damping-off”, or give temporary control until the seedling has passed its initial vulnerable stages of growth.

This includes sanitation in the general areas where seeds are being germinated.
