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.
