Dear Pamela, Bulb mites can also cause red blotches on Amarillidaceae. Here i use captan and tebuconazole (active ingredients) for red blotch, but i re-treat the bulbs-plants after 10 days and wait to see if new leaves are healthy. If the blotches are only on the bulb and on the leaves they appear as horizontal stripes/zones it is usually because of mites, which needs a totally different treatment.
