| From the pics it looks like you have some rot going on in addition to the scale. It appears that one mature growth and one new lead are black, and there is yellowing at the base of another lead. It's possible that the scale found an easy victim in a plant that was already weakened by rot. What I would recommend is removing all the black tissue and treating with Physan and/or coating the cut edges with cinnamon powder. Also do what Cynthia says (always do what Cynthia says!) and treat the scale with one of the Bayer products. You may need more than one application to kill it all. Make sure you isolate this plant from the others in your collection until you are sure it is healthy again. Best wishes for a speedy recovery! |
