Fungal infection on houseplants

What causes fungal infection on houseplants?
It depends on the plant and how it is kept, so check the plant pages below. For Cactus, the records explain it like this: Deep-seated fungal infection (often Phyllosticta or similar mycoses) that presents as white, scrapable specks. Unlike scale insects, these specks lack movement and return after removal because the mycelium survives within the pad tissue, especially at joints where humidity is trapped.
Common first steps
- Quarantine the plant immediately to prevent spores from spreading to other succulents.
- Surgically prune affected pads using a sterile blade, cutting into healthy tissue below the joint.
- Apply a systemic fungicide (propiconazole or tebuconazole) to treat the remaining healthy pads internally.
