Last night I went out to water my tomatoes (one plant out of 9) had flopped. No outside cause that I could find...it just fell. Doug cut back the offended branches and all but one were hollow. What causes this? I'll try to get pics in a bit...sleeping baby at the moment.

Tomato pith necrosis, caused by the bacterium Pseudomonas corrugata, is sometimes confused with bacterial canker. Initial symptoms include yellowing of young leaves. These symptoms may progress into yellowing and wilting of the top part of the plant. Black streaking may be apparent on the main stem, which often splits. When the stem is cut open longitudinally, the center of the stem (pith) will be hollow and often have a chambered (ladderlike) appearance. Profuse development of adventitious roots can be associated with the affected pith areas, and the stem may appear swollen.
