Clayton,

This reminds me, a nonfarmer, of a sentence I just read in a book
recently. Prompts me to ask: Is there any possibility you have
nematodes going on as well? Here is the sentence:

Nematodes can influence the production and accumulation of plant
growth factors. Increased hormone concentrations in nematode-
infected plants may contribute to greater infection by wilt-causing
organisms, because these growth factors make host tissues
easier to penetrate by maintaining cells in a rapidly dividing,
juvenile state.

Note the hedge word *may -- Something to look at.

Question for Elaine: Would Pseudomonas inoculum in tea help in wilt
part of this case? You recommended it once to Tim Livingstone on
this list for his work on powdery mildew of greenhouse-grown
strawberries. If so, source of Inoculum?

Also, some people are reporting that they are looking at the
calcium/magnesium ratios in the soil and verifying calcium in the
plant through tissue testing -- calcium in plant is said to be
important in strengthening cell walls. Here I am passing on
something I can't document to you from research or relate personal
experience, so I put it in the "interesting idea" category --
something to look into.
