Can anyone recommend a drosera-safe fungicide available in California that I can use on my drosera falconeri. Never had this problem until this year: I see hyphae and fruting bodies growing on the surface of the dried crowns. At first, I just removed the infected leaves and brushed with a light solution of isopropyl diluted with water but the mold continued to return. I need something a little stronger. Any recommendations (of a product that you've used yourself, know to work and be safe) would be recommended.
