For many reasons - viruses being just one - we only send out text mail on Aroid-L. Barbara, if you have a web site where you can post the picture, or if you want to e-mail the picture to Les Kallus to put up on the Aroid ID Center, I'm sure someone can identify the problem.

However, I recently had a very bad, fast-spreading fungus attack on my large patch of Colocasia 'Nancy's Revenge.' I cut them all back to the corms and sprayed with the fungicide Daconil. That seems to have solved the problem. Scott A. Lucas +More > Can anyone please help me identify the problem I am having with this > elephant ear? It is spreading to every plant.

From: Scott Hyndman hyndman at aroid.org> on 2003.08.27 at 13:08:28(10537) Barbara, Without the benefit of a proper pathology test and report, my educated guess from your image is that your Colocasia may be showing symptoms of some type of bacterial infection. Again, it is difficult to determine this from an image only, but small necrotic spots surrounded by a yellow halo pathology may be indicative of bacterial leaf pathogens. You might take a sample to your local extension service and ask them to send it to your state lab for analysis to determine exactly the pathogen. Have you sprayed with any pesticides or other chemicals recently? The other possibility is a phyto toxic response to a chemical application. The symptomology of certain types of phytotoxicity can be similar to bacterial leaf pathogenesis. Please keep us posted about the problem. I agree with Susan Cooper: Your garden is beautiful!
