Hi all, I'm always amazed that sulfur does anything. Still, it seems to work as a preventative for surface infections. I have not tried it ever, and I would not recommend it for treating any established, systemic fungal infections. For treating twin scaled bulb chips, sulfur would certainly be better than no antifungal treatment at all. For bulb chips, almost any antifungal agent that did not damage the plant tissue should be fine. I doubt that Captan has any specific properties that make it unique for protecting bulb chips.

I saw pictures on how to propagate Hippeastrum using double or twin scaling. Captan was suggested as a fungicide to dip the scales in for 30 minutes. I think captan is not sold to private persons in Holland (good thing dough). Could powdered sulfur a good alternative for it?
