botrytis on lily leaf
I have several Casa Blanca's coming up this year with blackened leaves that look scorched or burnt as they unfold. I did a search and it looks like it could be related to a fungus that was caused by the leaves being wet and cold at night, or it could be botrytis, or something that sounds like candida - which is a yeast in humans but I suppose there could a plant analog.
Does anyone know something organic I could spray on them to kill whatever the disease is? I can pick leaves off and destroy the plant material later in the season but I don't really want to discard the whole bulb if possible. I dug some and the bulbs look healthy.
