Here's another plant just a few days ago. It and all the rest of the eggplants have all the symptoms of Verticillium Wilt. Do a web search for Verticillium in eggplant and you'll find any number of photos showing eggplants that look like mine.
As the disease progresses up the plant it kills the flowers.
There are no know Verticillium resistant eggplant varieties available so I can't resort to that fix. One option that I may experiment with next year is grafting. All solanaceous plants are hosts for Verticillium, but there are resistant tomato varieties. Eggplants can be grafted onto tomato rootstocks and a resistant tomato rootstock can confer resistance to the eggplant graft.
Another option for growing eggplant in the future is growing them in containers using clean potting soil each year. This is a Sicilian eggplant that I'm trying to grow in a 5-gallon container. It has it's own woeful tale. It's tiny because it has been shrinking, it's had two major hits from Odocoileus hemionus.
How Verticillium got into my garden soil is a mystery, but the stuff gets around in a number of ways. It could have come in with infected soil, on contaminated seeds, in contaminated water, it can be transmitted by insects, and can even be airborne.
And the Odocoileus hemionus problem? My fault once, the FedEx guy the other time, the gate was left open and she just walked right in and started to browse.
