Hi Guys,
My English Elms are taking a beating from tiny little caterpillars eating the leaves. They are slowing the growth of the trees immensely and the trees look ragged. I've noticed that they particularly seem to like lower, weaker branches on the trees. I think they have even been eating the Zelkovas as well.
Anyone out there had the same problem? What did you do to treat the problem?
Thanks

Re: English Elm - Caterpillars
Thanks a lot guys.. I have some confidor so I'll start with that. If it doesnt work, then I'll go out and look for Mojo's recommendation.

Re: English Elm - Caterpillars
I thought I read somewhere that Elms and Confidor don't mix, can anyone confirm/deny this? My English elm has been eaten alive all summer, I have Confidor but have been too scared to use it.

Re: English Elm - Caterpillars
i know chinese elm dont like pesticides etc. at all
as for english elm i couldnt be certain but until it is confirmed i would wait, i know your tree is getting defoliated un intentionally by these buggers, if i was to try anything i would go with the molasses spray and see how that works, it seems more natural then any chemical.

Re: English Elm - Caterpillars
natrasoap may be an exception but i cannot be a hundred percent positive 
i would google if it is safe for chinese elm or someone might have personal experience with it.

Re: English Elm - Caterpillars
Elms don't like systemics, confidor is a systemic insecticide.
