I have an American Holly (Ilex opaca), planted in 1985, now over 20' high
- probably close to 25'. It has been sick for several years.
One person who claimed to be an expert on I.opaca said I should use Cygon
2E, in spite of the fact that it warned on the label not to use it on hollies. I did use it and almost killed the tree.I just sprayed it this morning with "dormant" fungicide spray ("97% mineral oil" according to the label). I was also going to spray it with a dormant insecticide, until I noticed a warning against using it on hollies.
There are a few pictures of affected leaves here:
Can anyone recognize the problem? Maybe *more* than one problem?
Solutions?
