Sick Holly
 

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 he

In fact many of the leaves are much worse - there is also a seedling of
about 2 1/2 feet which is much worse - many of the leaves are completely
dead.

Can anyone recognize the problem? Maybe *more* than one problem?

Solutions?

Sometimes you have to take the sick trees out and not plant new ones in
the same place for years. Looks nasty and with it on a nearby plant
contagious. If other folks in the neighborhood have Hollies it might
be advisable to have a county agent look at it for safe disposal.
