black mildew looking stuff???
Hi, I have black mildew looking marks on several leaves which started on our gumbo limbo trees. I sprayed at the beginning of Spring with no luck. I've recently seen that it has spread to any orchid close to the trees (and I grow outdoors)its also spread to palm tree leaves and turned them a dark brownish color through most of the leaves. If anyone knows what it may be, would Physan 20 help, its what I already have on hand... or is it something for an insecticide? Thanks for any help. AJ
I can email a pic if you need to see it on leaves... sorry, I couldn't figure out how to add the picture to this post.
