What is seedling blight?
Seedling blight is a fungal infection that causes the seed or seedling to rot and die. It can be characterized by patches in the field that fail to germinate. If the seedlings do manage to germinate, they may not emerge, or they may emerge and then become brown, pinched, and die. Other symptoms include stunted and yellow growth, or reduced root growth with brown spots on the roots and coleoptile.
