Last week it was mentioned that liquid copper is a good, mild anti-fungal
treatment and can be used as a soil drench. I noticed a few of the leaves
on my Ilex vomitorium (yaupon holly) turning brown. Last time that
happened, I lost a tree so I got a bottle of LCu. The instructions
indicated 4t/gal as a spray for ornamentals but didn't mention soil drench.

Did I hallucinate the soil drench part or did I miss something? Any other
thoughts about the I.v. would be appreciated. By way of background, this
plant has just recently been repotted and then moved into a hoop house to
protect it from "wind chill" drying. It's gotten down to the low thirties
outside but not freezing yet. Soil mix of pine bark and fired clay. Don't
want to lose this piece if I can help it. Thanks and have fun - jay

Be very careful using any copper solutions as a soil drench. Ionic copper
is highly toxic to the roots of plants in the quantities used in
fungicides. It will completely stunt the growth, if not kill the plant
outright. Been there, done that. Most copper formulations that are labelled
for a drench are completely safe, IF used as directed. BUT, if you soil pH
is very much lower than 6.5, the 'fixed' copper can be converted to ionic
compounds and the copper freed. Check your soil pH first and avoid
fertilization (acid forming) for several weeks afterward until the copper
is mostly leached out. If it doesn't mention a soil drench DON'T use it as one.

Nina, thanks for getting back to me and I'm glad if I gave you the
opportunity to reinforce your message. You'll note that I didn't use it, I
tried to confirm my impression that LCu could be used as a soil drench since
the labeling did not give that option. It did give instructions for spray
for powdery mildew, which we have a lot of on crepe myrtles etc. so I'm sure
I'll be using the spray. The holly has just been re-potted so you might be
right about the compacted soil. We'll see. Thanks again for getting back
and have fun - jay

Jay, it isn't you. I'm not yelling at you, I'm just yelling because this is
the 800th time I've had to say this. Read the freakin' label, people.
Copper is a common active ingredient in perhaps dozens of fungicides, some
of which are prepared as foliar sprays, and some of them formulated as
drenches. It's nice that pesticide companies formulate their pesticides so
they do what they're supposed to do; but it's your job to keep the names and
labels straight. I'd do a google search of "copper drench" and see what I
came up with. In fact, I came up with "Phyton-27", a very famous copper
spray. The label recommends a drench for verticillium on maple (which,
IMHO, won't do a thing) or for botrytis on all nursery crops. So, it isn't
labeled for haphazard use on your yaupon. Therefore, don't use it. Your
holly may be suffering from compacted soil, or nematodes, or who knows
what-all. Take it to a cooperative extension office, have the problem
diagnosed, and THEN decide on a treatment.
