Not Good News

Not Winning First Prize This Year
More bad news about the tomato plants.  Two weeks ago Cindy ripped out the Sweet Seedless tomato plant because it was showing clear signs of some kind of bacterial wilt.

Yesterday, she also ripped out the First Prize tomato plant for the same reason.  As you can see from this photograph, the plant was showing many yellowing leaves and the whole plant had begun to droop over the protective panels.

It had plenty of tomatoes on the vines, but, since the plant was dying rapidly, there was no chance the tomatoes would be able to ripen before the plant collapsed completely.

When Cindy took the plant down, she cut a cross section from the biggest part of the stem, that clearly showed the progress of the fungal wilt, which gradually plugs the xylem tissue and eventually cuts off the supply of water to the plant.

Plant Cross Section
Without a microscopic analysis, we won't know whether this is  Fusarium Wilt or Verticillium Wilt, but in either case, it's not good news for the tomato plant.
