Tracy.... welcome to NC!
For me the tomatoes seem to be coming in
2-3 weeks earlier this year due to the warmer/wetter April and now the elevated temps recently.
Of course, that mean the diseases/insects arrive earlier as well!
I've been hand picking a lot of stink bugs and worms as well. The recent rains have made it difficult to maintain a consistent covering of dipel to keep the worms away... thus the hand picking.
Did you talk to the owner of the produce stand about his results?
I wonder if any of the organic methods you used would be economically viable for him to take up.
