I had a Boophone inflorescence rot (no other damage) and also a Boophone bulb show similar signs of rot to your Brunsvigia. I dug it up - the bullb was actually rootless - and removed all dead/dying material, and am letting it dry. There was a very strong odor of acetate from the rotting scales. I would suggest you do the same. If the majority of the bulb is healthy, just re-plant. T > I discovered some rot in the upper old leaf bases of this Brunsvigia josephinae. It bloomed in August and September this year ... and we had a freak heavy rainstorm then followed by warm weather ... which I suspect is responsible for this rot. Any suggestions on treatment? Sulphur? A fungicide?
