dear main
since there is no email address i have to respond in the main list. i'm
sure you'll get a ton of answers, most of which will tell you it is
probably a fungus. that is one of the most prevalent affliction i have
noticed with my elms. i use a good spraying of orthenex and that usually
takes care of it. naturally, get rid of the black leaves.

be sure to spray top and bottom, trunk and soil. it works as a systemic
as well as a contact spray.
