That must be all over. My ex sis in law had a beautiful elm in her yard and it died of that. You never see them anymore. I wonder if it's one of those diseases brought over on ships. I understand before 1849 or so, corn never had the corn worms we have. I used to always have a garden and had to spray like the dickens to keep them away. I hated spraying so many pesticides and still ended up getting them to some degree. Didn't bother me too much, I think spraying the pesticides bothered me more but if I didn't, there would be no corn.
