I am happy to report that the bleach spray is a complete success.
The spots have stopped and new growth is forming on all Thai basil plants like it was never there.
I literally sprayed/soaked them every day for a week until the rain stopped.
What looked like sure death is no more.
Thank you so much Bill for your research and recommended mix.
Here are a few shots of the plants where the disease was and after.
Started out as tiny black spots on everything.
