NW15, if you decide to use a fungicide, I've posted a picture of those I use here--so at least you'll have some idea of what to look for and maybe make it easier to spot on a shelf while shopping. I don't promote any company here, only name them. All three are made be Bonide Products, inc. The one on the left is a liquid copper base that I use as a proactive spray against Botrytis, another dangerous above ground pathogen. The tall bottle in the center is a copper base powder version of the one one left and the one I sprinkle on the ground in early Spring. I also use this one to lightly dust my bulbs before planting and sprinkle a little around the hole or row as I plant. The one on the right is a non copper base powder fungicide that I use interchangably with the copper base powder but most usually use this one to powder my bulbs and also add it to my soil mix to prevent Damp-Off, not only for lily seed sprouts but any other vegetable or flower seed sprouts that's prone to Damp-Off. All this might sound like a lot of extra work but really, it's not when spread out over the course of a year. And, I've always found the easiest way to deal with fungi and deseases is to prevent them in the first place.
