Excerpts
from a Phone Conversation February 6th
Maria:
Well, the pH was 6.32, which I thought was a little low, so
I went ahead and applied the CaCO3 drench.
However, the symptoms are just getting worse and worse, and
now they are appearing on more plants.
Extension
Horticulturist:
Did your EC check out as fine?
Maria:
Sure did. Readings were 0.36-0.4 mmhos/cm.
Extension
Horticulturist:
How does the root system look?
Maria:
Fine. It's plenty vigorous with mostly white roots; only older
ones were kind of woody, so they were more brown. I really
don’t think that there is any root rot problem.
Extension
Horticulturist:
Is your insect scouting still turning up no pests but fungus
gnats and shore flies?
Maria:
Right. That’s still the case.
Extension
Horticulturist:
Are the affected plants still showing up in a random fashion?
Maria:
Yes. And the chlorosis is now a darker yellow color and has
definite wavy bands towards the leaf edges. The younger leaves
are even starting to look wrinkled and puckered. I’m
getting concerned.
Extension
Horticulturist:
This is a dilemma. Again, without seeing the plant it is hard
for me interpret the symptoms, but several causes of the problem
can now be ruled out...
[The Extension Horticulturist continues to outline the various
causes of the problem that can be eliminated based on available
information and suggest a course of action for Maria to follow.] |
